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 has obtained permission (the user said that using the right-click of the Rubik's cube to obtain administrator rights can be authorized, you can try, I did not succeed with the song)~
BTW: This will reduce system security, In order 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, because this directory is hidden, view hidden files as follows Operation: Ribbon menu view >> [Check] hidden items
2. Get the permissions of this folder, this step is very important~
(1.) Right click on 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, OK~
(3 .) After After the owner will appear your account name, 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 period of time~
3. After the authorization is completed, you You can do this on the folder. Open the folder and 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 times to delete the old version. If you can't tell the date of the change, you can put it in the recycle bin first, and then see if the application can open normally. Don't delete the error. Otherwise, uninstall the application and go to the app store to install it~
Other: 64-bit system will have x86 and x64 directories at the same time, keep them confusing
and these files The folder is very important, don't just delete the x86 all the time, the consequences are not known, you can try O (∩ _∩) O ~
At this point, Win8 redundant application clearance has come to an end, most Do not make other changes~
Second, clean Win8 application cache
Win8 application cache directory and set directory are saved in the user folder, the default path is C:Users[account name]AppDataLocalPackages, system variable is % LocalAppData%Packages
The application cache is located in the AC folder of the subdirectory corresponding to the directory of the Win8 application. There are generally three folders: INetINetCookies, INetCache and History. These three brothers are also cleaned up.
Remember: Packages and subdirectory files can't be deleted casually!!! Once you delete other files other than cache, all applications will flash back, you can only re-create new accounts or reinstall the system!
I don't Know whether the system regularly cleans up the application cache, but every time you clean up, you can free up a lot of space, especially after watching the video~
1. The cache folder is system protected. To view it, you must cancel the "protected" Check the operating system file & rdquo; as follows:
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 folder in the AC subdirectory of the application directory
3. Of course Easy to delete, you can search for Iet directly in the Packages directory, then select all, delete it, this can be deleted without any scruples.
3, 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, here thank. Now provide the program to everyone, if you have any questions, please point out, thank you!
1. Enter the advanced interface of 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. The Win8 application folder is blocked again~
