Font cache can be deleted. Delete junk files with CCleaner: a beginner's guide. Font caching in the browser
VLC is one of the most popular media players across platforms. Users choose it for its simple interface, support for a large number of different formats and many settings. However, also VLC there are shortcomings. For example, some users have reported font caching periodically renewing.
Font Cache Creation Message may occur when starting the player and "hang" for a long time. Some note that the cache can be created / updated several times in a row. Moreover, this problem has existed for a very long time.
You can solve the problem in the following way:
1. Open the VLC application.
2. Open application settings. You can call them with the key combination Cmd +,
3. In the lower part of the settings window, click the Show all button.
4. In the left column, select the item Video - Subtitles / OSD.
5. In the right part of the window, in the Text visualization module item, select the Dummy font renderer item.
After that, the message about creating the font cache should stop appearing.
Hello dear readers, today I would like to talk about:
1. ABOUT Windows Services what it is, what it is for and which ones are responsible for what.
2.And how to increase the speed of the computer?
So what are these Windows services?
Services- applications that are automatically or manually launched by the system when Windows starts and perform various tasks regardless of the user's status.
Open list of services can be done in several ways:
1. While holding the windows button, press R, a window will open, enter services.msc there
2. Start > Control Panel > Administrative Tools > Services
3. Start > right click on my computer > Manage > Services and Applications > Services
As you can see, there are a lot of them in Windows and after downloading, you can familiarize yourself with what services exist and what each of them is responsible for.
Since services are applications, therefore they run and use part of the computer's resources. you can increase its speed. Let's see what can be disabled.
What services can be disabled in Windows 7, 8
I did not begin to make a list of those services that can be disabled, because. many services are individual. I just tried to describe each service and in what situations they can be disabled. If you need to disable something mindlessly, then just use .
* BranchCache- The service caches network content. If you do not use a home network, then you can turn it off altogether.
* DHCP Client - If you use the Internet, do not touch in any case. It is this service that assigns you an ip address.
* DNS client — It is also a necessary service for using the Internet. Works with your DNS (serves for the right directions).
* KtmRm for Distributed Transaction Coordinator − transaction system function. We leave it the same.
* Microsoft .NET Framework - All such services are left as is. They serve for the normal operation of most applications.
* Parental Controls- Service for parental control. If you don't use it, you can turn it off.
* Plug and Play - serves to automatically recognize changes in the system. For example, when you connect a flash drive, this service wakes up ... So we leave it as it is.
* Quality Windows Audio Video Experience - transmission of audio and video over the network in real time. It is not needed only if there is no network (or Internet) in other cases, we leave it.
* Remote Desktop Configuration - For remote desktop. If you do not use remote connections, disable.
* superfetch- A useful feature that works with the cache. Speeds up Windows, so leave it.
* Windows Audio - Controls sound. Turn off the sound if you don't need it. In other cases, leave.
* Windows Card Space - unnecessary and unsafe service. We disable this.
* Windows Driver Foundation - User-mode Driver Framework - for the normal operation of the drivers, do not touch. Let it stay as it is.
* Windows Search - Indexing files for searching. If you do not use it and there is time to wait until the file is found, then disable it. On ssd, be sure to turn it off!
* WMI Performance Adapter - needed for services requiring wmi, set manually. If some applications need it, they will launch it themselves)
* WWAN Autoconfiguration - service for using mobile internet. If you use a usb modem, a sim card in a laptop, then do not turn it off.
* Offline Files - helps to work offline with inaccessible files that have been downloaded before. We put it manually.
* Network Access Protection Agent - We put it manually, because. if necessary, the service will start if some program requests the necessary information.
* AIPsec policy agent - Required if you have a network and the Internet.
* Adaptive brightness control - We leave if there is a light sensor.
* Windows Backup - Disable if not in use. But it’s better to read about archiving in windows, you never know, you will use it.
* Windows Biometric Service - needed only when using biometric devices. In other cases, disable.
* Windows Firewall - To be honest, I always turn it off. I have nothing to steal) And if they encrypt the data, I will restore it) But I advise you to get, for example, Kaspersky Internet Security, which has both an antivirus and a firewall. And turn off this nafig, tk. it sometimes blocks what is not needed) In general, it monitors the security of your computer and closes ports so that thieves cannot get into your computer)

* Security Center - Monitors Windows security. She annoys me with her notifications. So turn it off or not, the choice is yours.
* Windows Update - On the one hand, it's a useful feature. It closes holes in the system, updates drivers, but on the other hand, it actively uses the Internet, memory resources, and if you turn off the computer during the update, the OS may crash. So it's up to you to choose what is more important, security or speed.
* Encrypting File System (EFS) - For file security. Better to leave it as is manually.
I tried to present the entire list of services. By disabling some, you will increase the speed of your computer. You can also decide at your own discretion which ones are needed and which are not. For example, if there is no Internet, then you can safely cut half of it, if there is no printer, then you can also turn off a lot. Thus, depending on your needs, you can significantly cheer up an old computer.

A program for total cleaning of the hard drive from garbage called CCleaner quite popular. It is powerful, free and easy to use. However, its simplicity is only apparent: CCleaner is quite a powerful tool and in inept hands can harm programs and Windows.
Download CCleaner
Program home page: link.
The best way to download the program is from here. this pages is the official site.
Attention! CCleaner for mobile devices is a completely different product and has nothing to do with CCleaner for Windows. Mobile CCleaner has one fatal flaw: users often delete important data with its “help”. Recover data deleted on a mobile phone, But if you delete something from your computer, no matter what program, there is a chance to restore it - read Moreover, CCleaner for Windows does not delete anything really important, so just read the instructions carefully and everything will be fine.
Program installation
Installation is simple. I advise you to uncheck the box during installation. Add to Recycle Bin menu item ‘Run CCleaner’. The fact is that after installing the program in the menu of the Recycle Bin shortcut, in addition to the item clear, CCleaner launch items will be added. Function Launch CCleaner not only starts the program, but also causes the cleaning process. If the program is not configured properly, something useful may be removed. So uncheck the box, there will be only one safe item in the menu - Open CCleaner. It's enough.
Using the program
CCleaner is launched either through the Start menu, or from the Desktop, or through the Recycle Bin menu by right-clicking the mouse. When you first start the program, you will be asked about cookies:
The program has a lot of buttons, so instead of traditional
for my blog of pictures with explanatory inscriptions
have to tell everything in text
On the left side of the CCleaner window is a selection of functions:
- cleaning- actually cleaning the hard drive from unnecessary files
- Registry- cleaning the Windows registry from entries
- Service- there are various lists and the function of "clearing free space on the hard disk". Why this is necessary, I will tell further in the text.
- Settings- here you can configure the program, for example, clean up when you start the computer, change the interface language (although it automatically becomes Russian on Russian Windows), as well as other functions that I will talk about in the corresponding chapter.
cleaning
The most powerful and interesting feature of this program. When choosing a mode cleaning tabs and an empty field for the report appear in the right part of the window. Tab Windows is responsible for cleaning up places that are always present in the Windows operating system. The Applications tab is responsible for third-party programs, such as Mozilla Firefox, Google Chrome, Opera browsers, Google Earth, Skype, AIMP and others. The list changes depending on what is installed on your computer.
Unfortunately, CCleaner does not recognize too many programs, but this can be fixed in two ways, the first of which is described in the chapter Settings - Inclusion Tab, and the second in the chapter , where I will talk about the program CCEnhancer.
Button Analysis at the bottom of the window starts the counting process - how much space can be cleared. The calculation is very approximate, keep this in mind.
Button cleaning starts the cleaning process. Only those files that have been checked in the tabs are deleted.
The results of analysis and cleaning appear in the empty field on the right side of the window.
Windows tab
Items are grouped into sections depending on the program or the meaning. If an item offers a chance to free up a lot of hard drive space, I'll mention it. in bold.
Internet Explorer:
Temporary browser files- files that are added by the browser in order to take them from the hard disk instead of downloading from the Internet again. For example, when you visit a page again, pictures are most often loaded from your hard drive, and not from the Internet. This speeds up the opening of pages. Temporary browser files are also called browser cache or browser cache. Check the box boldly, it will not cause harm. Can free up a lot of space.
Visit log- this point is clear. Any browser, including Internet Explorer, stores a list of visited sites for a certain period of time, most often 20 days. This is useful, because then a tooltip with the full address of the site appears when you enter it. You can check the box, it won't do any harm.
Cookies- these are files where site settings are stored. Thanks to cookies, sites remember your passwords, stores remember your shopping list, a mail site remembers your e-mail, and so on. If you check this box, then these files will be deleted and logins with passwords will have to be re-entered everywhere. Clicking Settings - Cookies, you can add to the "save list" the addresses of those sites whose "cookies" do not need to be deleted. Comfortable.
List of entered addresses- I think this is understandable. In addition to the log of visited sites, there is a separate list of addresses entered in the address bar. To put a daw or not - it all depends on you.
Index.dat files- in fact, this is the same as the previous points combined. Some of the information about visited sites, files in the browser cache, etc. is also stored here. If you check the boxes above, check here as well.
Last download path- a record of the folder where you last uploaded the file. Deleting this entry will only affect the fact that the next time you download the file, you will be prompted to save it to the Downloads folder in your profile. The option is practically useless.
Autocomplete Forms- when you enter text (for example, logins) on sites, the information is remembered by the browser. Next time the text will be suggested for entering in the same or similar fields. This information can be removed.
Saved passwords- thanks to this function, even after deleting cookies, the entered passwords can be automatically substituted into the text fields. A function similar to the previous one, only works with text fields containing passwords.
Session- information about the last opened tabs. For example, if you set your Opera or Firefox browser to open the most recently opened tabs when you start, this information will be deleted.
Windows Explorer:
Recent Documents- in the Start menu there is a menu item "Recent Documents". This is where you can clear the list.
Run (in the Start menu)- clearing the list that appears in the text field of the Start - Run window.
Other recent properties- I do not know what this item is responsible for. I would be grateful if someone could tell me about it.
Thumbnail cache- when you open folders with photos in thumbnail (thumbnail) view mode, these thumbnails are saved so that you can quickly load them next time instead of recreating them. They do not take up much space, but I recommend deleting them at least once a month.
Quick Access Lists- a useful feature that first appeared in Windows 7. Its essence is that when you hover over a line with a program in the Start menu, a list of documents recently opened by this program is displayed on the right. Also, it can be any functions. The same list appears if you right-click on the name of the program in the taskbar.
Network passwords- I think what this item is responsible for, no need to explain.
System:
Emptying the trash- the meaning of this paragraph is clear.
Temporary files- cleaning the TEMP folder. It is there that most of the garbage that is created by programs during operation is located. For example, if using an archiver (7zip, WinRAR or some other - it doesn't matter) open a file from an archive without unpacking, i.e. directly, then this file will first be unpacked into the "temporary Temp folder" and only then will it open. I recommend checking the box - in some especially neglected cases, you can free up a couple of gigabytes.
Clipboard- a place in RAM where the copied text or other object is stored. Why clear it is not clear, anyway, when the computer is turned off, its contents are lost.
Memory dumps- if a crash occurs and the computer shows a BSOD ("blue screen of death"), then Windows can urgently save information about what caused the error. If there are a lot of BSODs, then there will be a lot of these files. You can check the box, but first you need to figure out the cause of the BSODs. This is well told
Chkdsk file snippets- in a situation where part of a file is lost (for example, in the event of a power failure), these files are created after checking the hard disk. Designed to recover lost information, but they are not needed by a non-specialist. Can be deleted.
Windows log files- deletion of some files that are not particularly needed for long-term storage, such as CBS.log - a report on checking the integrity of Windows system files. Contrary to popular belief, this item does not clear the Windows Event Logs - records that the operating system makes during all errors and successful actions. They are available in Control Panel - Administrative Tools - Event Viewer. By the way, a very useful feature for troubleshooting. But CCleaner has nothing to do with the item. It is recommended to check the box.
Windows Error Reporting- we have all encountered the windows "Program such and such made an error and will be closed." This item deletes files containing error reports from programs and Windows itself. It is recommended to check the box, there is a chance to free up a lot of space.
DNS cache- probably, this is a feature added by CCleaner programmers "to the heap". With the help of DNS servers, the computer learns the digital IP addresses of sites in order to open them. For example, google.ru has the address 173.194.32.223. So that each time you do not have to access DNS again, Windows remembers the correspondence of addresses for a while. This list of matches can be cleared.
Font cache- if you have problems with fonts (the length of spaces has changed, instead of letters, squares), you can check this box - the next time you boot, Windows will re-create a list of the most commonly used fonts. The option is controversial, since the size of the font cache is quite small - there is no point in deleting it to free up space. Windows itself monitors its maintenance. To clarify - the font cache contains not only a list of fonts, but also some service information. On Windows Vista and 7 it is in two files:
C:\Windows\system32\FNTCACHE.DAT
C:\Users\Username\AppData\Local\GDIPFONTCACHEV1.DAT
On Windows XP, the font cache is located only in C:\Windows\system32\FNTCACHE.DAT.
Main menu shortcuts- checks the correctness of shortcuts in the Start menu. If a shortcut leads to a non-existent program or other file, then CCleaner will delete it. The item is useful, but only after deleting the wrong shortcuts, empty folders remain where these same shortcuts were - do not forget to delete them manually.
Desktop shortcuts- similar to the previous paragraph, but with desktop shortcuts.
Other:
Legacy selections- removes supposedly obsolete data of the Prefetcher component, which speeds up the loading of Windows and programs. The usefulness of CCleaner's selection clearing feature is questionable, as the component can maintain itself.
Menu Order Cache- removes information about sorting lines in the Start menu. After cleaning, all items will line up alphabetically.
Notification area cache- icons in the tray (near the clock) can be configured by forcibly hiding or showing (right-click on the Taskbar - Properties, then the Customize ... button). With CCleaner, you can reset these settings.
Window size cache- reset information about the size of the Explorer window (hint for beginners: Explorer is a program that displays folders, including My Computer).
environment variable- removes invalid folder addresses in Windows "PATH environment variable". Information about what "environment variables" are is unlikely to be useful to novice users. If you are interested, you can take a look and it is better not to tick the item, because in case of a failure there will be serious problems with the performance of Windows.
List of recent programs- Clears the list of recently launched programs in the Start menu.
IIS log files- clears the C:WindowsLogFiles folder. In principle, you can check the box, the program will delete a couple of megabytes of unnecessary information. This function will release more information only in server versions of Windows.
Other files and folders- the item is responsible for deleting folders and files specified in Settings - Inclusions.
Free space cleaning- the same as Service - Disk Erase, but in automatic mode and without deleting files. I will talk about this function in the chapter Service. It is better not to check the box - cleaning up free space takes a lot of time.
Applications tab
Here the number of points varies. CCleaner checks what programs you have installed, then builds a list based on that information. Cleaning up temporary, unnecessary program files is useful because some of the "programming creations" love to litter. This is especially true for antiviruses.
There was a fly in the ointment without a fly in the ointment: in rare cases, CCleaner can remove program settings. If your favorite program suddenly "forgot" the settings, the problem is most likely in CCleaner - no longer check the item with the name of the program in the cleaning list. It's not critical, but annoying.
If you are not surfing the Internet through Internet Explorer, then in the list, pay attention to the items with the name of your browser. The same settings are there, only "Temporary Internet files" are called "Internet cache". There were also items Session" And " Compress databases". Session (session) in browsers is a list of open tabs with sites. You can configure browsers so that when you start the browser, the sites that you viewed in the last session of work are opened, i.e. the previous session was loaded.
The second item causes the defragmentation of files containing logs of visited sites, bookmarks, various service information, and the like. According to my observations, the "database compression" function does not bring any result, although in theory the browser should load faster.
Perhaps these are all tips regarding the tab Applications.
Registry
This is the name of the section of the program, from which everyone is delighted in the same way as from the function of cleaning files. Alas, if cleaning up files brings obvious benefits - free space on your hard drive, then the usefulness of cleaning the registry is a myth. Or at least an exaggeration.
The registry is a huge database that stores Windows and program settings. There are over 100,000 entries. Even the most "corrosive" registry cleaner will not find more than two thousand entries that are erroneous or not used. Such a small amount (0.02% ± 0.01 records) will not do the trick. But problems are possible:
The first problem is that supposedly erroneous records may be correct. All registry cleaners, including CCleaner, rely on the most important argument - if an entry contains the address of a non-existent folder or file, then such an entry is erroneous and must be deleted. Unfortunately, this does not take into account the fact that this folder or this file may be created in the future and the entry is made for this. That is, it can be a setting in some program to create a file in a specific location. Outcome- a failure is likely in the program, the setting of which has been deleted.
The second problem is registry fragmentation. Fragmentation is one of the problems of the Windows registry. The fact is that the registry is stored in several files that can be scattered throughout the hard drive. Yes, not just scattered, but divided into small pieces (file fragmentation). As a result, in order to read one record, the hard disk head will have to rush back and forth on the hard disk, which significantly slows down operations. Although Windows deals with this problem by caching (preserving) the contents of the registry in fast RAM, there is a problem of fragmentation of the data itself. inside files, namely inside the Windows registry files. Imagine the situation: in order to open a file from the middle of the folder list, you have to exit this folder, scroll through the list, go to the folder with the same name and find this file there. This is approximately the kind of confusion that occurs in the registry entries in the process of creating new entries - physically the entries are not written next to each other (everything is already busy there, and the file cannot be “stretched”), but at the end of the file. After such confusion, a computer with Windows installed starts to slow down. Usually it becomes noticeable after six months or a year of work. No registry cleaner will help., only him, and CCleaner can't defrag. Moreover, after deleting entries, new ones are not written in their place, as a result, something like unused empty spaces appears in the structure of registry files, in fact, this is an increase in the fragmentation of registry entries.
I will list what Ccleaner is trying to clean from the registry:
- Missing shared DLLs
- Invalid file extensions
- ActiveX and Class Errors
- Type Libraries
- Applications
- Fonts
- Application Paths
- Help files
- Invalid installer entries
- Missing Applications
- Organizing the Start Menu
- Temporary MUI files
- Sound events
- Windows Services
In principle, you can easily clean the registry with CCleaner, since it is suggested that you create a backup file before “correcting errors”. In case of glitches, you can double-click on this file, agree with the question that appears - the deleted registry entries will be restored. The downside of all this is that fragmentation will increase by about 0.0001%, which is not critical in the short term, but if you do this daily, then wait for the brakes.
Outcome: there will be no benefit from cleaning the registry, but you can feel the acceleration of Windows due to the placebo effect.
Service
This section of the program is divided into several subsections:
Uninstalling programs
A list of installed programs is displayed here. You can uninstall programs in the same way as it is done through Installing and uninstalling programs in Windows XP and Programs and Features in Vista and 7. There are also additional features: a button Rename will change the line with the name of the installed program (I do not recommend doing this, there may be glitches), and the button Delete- delete the line with the program without deleting the program itself. Moreover, the button Delete useful in cases where you uninstalled a program, but for some reason it remained in the list of installed programs. This also happens after renaming a program in the list using the button Rename. By the way, when cleaning the registry, CCleaner finds erroneous entries in the list of uninstalled programs and removes them, but you should not rely on this function, because the detection rate is low.
Autoload
Windows tab
It stores a list of programs that start when the computer is turned on. You can remove them from this list, or temporarily exclude them, or re-include them in the list. True, not all places where programs can start from are taken into account, therefore, for this task, I advise the Autoruns program, which I wrote a review about on the acerfans.ru website: Increasing the speed of Windows using Autoruns.
Internet Explorer tab
This is where the list of components installed in Internet Explorer is stored. I wrote more about the components of Internet Explorer in an article posted on the aforementioned site: Speeding up browsers
Scheduled Tasks tab
Displays a list of the Windows Task Scheduler component. These jobs can run any time the computer is running, depending on conditions. I do not recommend touching this list, because the Task Scheduler is a rather "capricious" component, it likes to give errors when third-party programs intervene.
System Restore
Restore points are displayed here - thanks to them, you can restore Windows settings and programs to an earlier time. Through CCleaner, you can selectively delete restore points. The System Restore component itself, which creates these points, is available through the menu Start - All Programs - Accessories - System Tools - System Restore.
Erasing a disc
This function duplicates the function with a similar name in the section cleaning. Its purpose is to prevent the recovery of deleted files. To understand why and who needs it, you should know how information is stored on hard drives.
In short: there is a file system (this is a special record on the hard disk) that contains data that such and such a file with such and such a name or even names is located on the hard disk at the address such and such. The file system also stores records about folders, security properties, and other service information - it all depends on the version and purpose of the file system. If the file needs to be deleted, then the record about the file is deleted, but the file itself is still on the hard drive. Over the place where this deleted file is stored, other files can be written, and it does not matter whether the old file is completely overwritten or only part of it is affected. As if there is no file, it is considered free space. However, since the file physically exists, you can use it in whole or in part with the help of special programs. Moreover, with the help of special technical means, at least partial restoration is possible even overwritten file! This fact scares people who are concerned about the privacy of the information they work with.
There are techniques by which you can reduce the chance of recovering deleted information to zero. That's what it does Erasing a disc in CCleaner: using special algorithms (there are four of them to choose from), the program generates data that clogs free disk space. That is, invisible to the user, but physically existing, the data is overwritten with other data. The program can overwrite both free space and the entire disk.
Conclusion: the function is needed for those people who do not want their data to be restored after deleting files from the Recycle Bin.
Settings
Settings
Here the names of all items are clear, except for the cleaning settings:
They are responsible for the way to delete unnecessary files - normal deletion similar to deleting from the Trash, i.e. files can be restored back (see section Erasing a disc), permanent erasure reduces the chance of recovering deleted files to almost zero.
Option Clear free space MFT allows you to delete unnecessary information in the MFT - the Main File Table, where all information about files and folders on hard drives with the NTFS file system is stored.
The question arises: what will happen if we clear the free space in the MFT?
Answer: nothing bad will happen. But the chance to recover deleted data will decrease many times over. As for increasing performance with MFT cleaning: I did MFT cleaning on several computers, I did not notice an increase in the speed of reading and writing files. So I never clean up the MFT.
For this option to work, you must check the box. Cleanup - Clean up free space.
Cookies
What is a cookie, I told at the very beginning of the article - see the Internet Explorer information clearing section.
In the window you will see two lists. The left list is a list of all the "cookies" of the sites you have visited. The list on the right side of the window contains cookies that CCleaner deletes. will not be.
By selecting the necessary lines (you can select several at once with the help of the pressed Ctrl or Shift), using the two buttons in the middle, you can move them between the lists.
Inclusions
So we got to the "tasty" features of the program.
On this tab you can create your list of folders and files to delete. This is the window that appears when you click the button Add:
The function is made conveniently and clearly, it makes no sense to talk in detail about all the buttons. The only important point: the function will work only if in Cleanup - Windows is ticked on Other files and folders.
Exceptions
The function is the reverse of the previous one. Allows you to compile a list of files, folders and registry entries that should never be deleted. Unfortunately, the feature is deprecated. In the help, the developers honestly indicated that if you add a folder to the list, then this does not add files in subfolders to the exclusion list (folders nested in this folder, sorry for the tautology).
Additionally
Here are some interesting settings:
Show results in detail view- the program always makes a detailed report on deleted files. However, you can right-click on the text of a regular report and select Detailed Results there - the effect will be the same.
Delete files from Temp folder only if they are older than 24 hours- it is better not to uncheck the box, because although the Temp folder is intended exclusively for "junk files", some recently created files can be used by programs. Removing them will cause such programs to malfunction.
Delete only files older than 25 hours from Trash- the meaning of the option is clear. If you often mistakenly send files to the Trash, it is better to check the box. Hide warnings- the meaning of the option is clear. It is better not to check the box - warnings in such a program have a certain value.
Close the program after cleaning- if CCleaner closes after cleaning, we will not see a report on the amount of freed space, so it's better not to check the box.
Request registry backups- for the sake of your computer, I advise you to leave the checkbox. The registry backup file can be deleted later manually when you make sure that there are no glitches after cleaning the registry.
Minimize to the notification area- after minimizing the program window, the button in the Taskbar will disappear and a small CCleaner icon will appear near the clock.
Store program settings in an INI file- a useful option for those who store the folder with the program on a flash drive and want to have the same settings on all computers where CCleaner is launched. The settings will be stored in a file in the folder with the program.
Jump List Tasks- if the option is enabled, then right-clicking in Windows 7 on the CCleaner button on the Taskbar displays the following lines with actions:
The archive is downloaded, the program can be run from there without unpacking:
Click Download Latest and we are waiting. The program will download the winapp2.ini file from its website, which contains information about junk files and folders of many programs. Then the question will be:
Click Yes, CCleaner will start. There will be clearly more points in it! New entries will be marked with an asterisk *
In the future, you can periodically run CCEnhancer to download a new version of the winapp2.ini file so that CCleaner keeps up with the times by recognizing modern programs.
Attention! Added cleaning items not tested by the developers of CCleaner, something wrong may have been removed!
Attention #2! CCEnhancer does not work with portable versions of CCleaner and various repacks. Correct operation is guaranteed only if CCEnhancer is properly installed and run as an administrator.
How to find out what CCleaner wants to remove when one or another item is working
Let's say you are wondering what will be deleted if you check an item or items. To do this, check the boxes, press the button Analysis, wait for it to finish, then right-click on the lines with the results of the analysis - Detailed results. You will see a list of files that CCleaner wants to remove.
Checking and unchecking a group of rows
You can right-click on the Windows and Applications tabs:
And you can only by the list section:
Thus, you can not only check the checkboxes on a group of lines, but also call Analysis With Cleaning.
Outcome
This guide to CCleaner is perhaps the most detailed on the Russian-speaking Internet. I have told almost everything about this program. I hope this helped someone.
