Win8 system how to quickly clean the metro application cache and safely delete the old version

First, delete the old version of Win8 application

Win8 application installation directory in the system disk, the default path is C: Program FilesWindowsApps, system variable %ProgramFiles% WindowsApps

This folder does not have permission to access even the administrator account. You can add the current administrator to gain permission. (There is a user who can use the right button of the Rubik's cube to obtain administrator privileges. You can try it. I used to. That song has not been successful)~

BTW: This will reduce the security of the system. To ensure the stability of Win8 application, after obtaining the permission, make too many changes~

1. Go to the C:Program Files directory and you will not find the WindowsApps folder. Since this directory is hidden, view the hidden files as follows: Ribbon menu view >> [Check] hidden items

2. Get the permissions of this folder, this step is very important ~

(1.) Right click on the WindowsApps folder - Properties - Security - Advanced

(2.) By default, the default display in the owner will not display the current owner, click on the changes that follow, add your current account name, and determine ~

(3.) after all After the account name will appear, check the replacement sub-container and the owner of the object below, and then click OK below, the authorization process will be carried out for a while~

3. After the authorization is completed, you will You can do this with the folder. When you open the folder, you will find duplicate directories (if you have updated the application), but the later version numbers are different.

The next thing to do is to hold down Ctrl and select multiple, delete the old version. If you can't tell the date, you can put it in the recycle bin and see if the app can open normally. Don't delete the error, otherwise you will uninstall the application and go to the app store to install it~

Another: 64-bit system will have x86 and x64 directories in some applications, so keep it confusing

And these folders are very important, don't just delete all the x86, the consequences are not known, you can try O(∩_∩)O~

At this point, Win8 redundant application The clearing is coming to an end, it is best not to make other changes~

Second, clean up the Win8 application cache

Win8 application cache directory and settings directory is saved in the user folder, the default path is C :Users[account name]AppDataLocalPackages, the system variable is %LocalAppData%Packages

The application cache is located in the subdirectory AC folder of the directory corresponding to the Win8 application. There are generally three folders: INetINetCookies, INetCache and History. To clear It is also the three brothers.

Remember: Packages and subdirectory files can't be deleted casually!!! Once you delete other files that are not cached, all applications will flash back, you can only re-create new accounts or reinstall the system!

I don't know if the system regularly cleans up the application cache, but every time I clean it, I can free up a lot of space, especially after watching the video~

1. The cache folder is system protected, Check the checkbox to remove the "Hide Protected Operating System Files" checkbox:

Ribbon Menu View >> Options >> View >> [Uncheck] Hide Protected Operating System Files & [Check] Show hidden files, then you can see the cache folder

2. Everything goes well, then you can view the cache in the AC subdirectory of the application directory. Folder

3. Of course, for easy deletion, you can search for Iet directly in the Packages directory, then select all, delete it, this can be deleted without any scruples.

Third, return WindowsApps permissions

To return to the original permissions, in fact, Qing Feng does not know what permissions are in the beginning, with the help of the altar friend pianaiw, finally found a way, Thank you very much. Now provide the program to everyone, if you have any questions, please point out, thank you!

1. Enter the advanced interface of the security options, click on the owner to change, enter NT SERVICETrustedInstaller, you can add TrustedInstaller account ~

2. Then check the owner of the replacement subcontainer and object below, and delete the current account, then click OK, the folder will be reauthorized, and the authorization will return to the default permissions~

3. Ok, the Win8 application folder is blocked again~
