delete the old version of the Win8 application
Win8 application installation directory in the system disk, the default path is C: Program FilesWindowsApps, WindowsApps folder does not have access to the administrator account, You can add the current administrator to obtain permissions (this will reduce system security, to ensure the stability of Win8 applications, do not make too many changes after obtaining permissions).
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 < Br>
2. Get the permissions of this folder, this step is very important, please be sure to follow the steps.
(1) Right-click on the WindowsApps folder - Properties - Security - Advanced
(2) By default, the default is displayed in the owner. The current owner cannot be displayed. Click on the changes that follow to add your current account. Name, ok.
(Note: The account name to be entered is the name entered when the system is installed, the computer - right click - management - local users and groups - users - - see if there is a name that you set yourself That is the one! It is "name", not "all name" (recommended to see this article) or as shown below, click on the advanced - immediately view - from below to see that you set Username, if you are a Microsoft ID login, it is Microsoft username + email address, select the one!)
(3) After the owner will appear your account name, check Replace the subcontainer and the owner of the object below, then click OK below to proceed with the authorization process for a while.
3. After the authorization is completed, you can operate the folder. Open the folder and you will find duplicate directories (if you have updated the application), but the 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, it is recommended to put it in the recycle bin first, and then see if the application can open normally. Don't delete the error. Otherwise, uninstall the app and go back to the app store.
Others: Some applications of 64-bit systems will have x86 and x64 directories at the same time, so keep them confusing.
and these folders are very important. Don’t just delete x86 all at once. I don't know the consequences, you can try O(∩_∩)O.
At this point, the removal of Win8 redundant application comes to an end, it is best not to make other changes ~
clean Win8 application cache
Win8 application cache directory and settings directory saved in the user folder, the default The path is C:Users[account name]AppDataLocalPackages, the system variable is %LocalAppData%Packages
The application cache is in the subdirectory AC folder of the corresponding Win8 application directory. There are generally three folders: INetINetCookies, INetCache and History. The three brothers are also to be cleaned up.
Remember: Packages and subdirectory files cannot be deleted! ! ! 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 it can be released every time. A lot of space, especially after watching the video~
1. The cache folder is system protected. To check, you must uncheck the "Hide protected operating system files" check box, 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 is going well, then you can view the cache folder in the AC subdirectory of the application directory
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.
Delete must be careful to first move to another place", don't worry about going to "permanently delete". Leave yourself behind the road.
Return WindowsApps permissions
To return to the original permissions, in fact, Qingfeng does not know what permissions are in the beginning. With the help of the friend Pianaiw, I finally found a way to express my gratitude. Now provide the program to everyone, if you have any questions, please indicate it immediately, thank you!
1. Enter the advanced interface of the security option, click on the owner to change, enter NT SERVICETrustedInstaller, you can add the TrustedInstaller account.
(Note: Win8e.com 800 million net authors today reported the first error when returning the permissions, so they re-operated a return operation, only succeeded, in order to verify, repeat this operation again. Finally assured Because many students are very recklessly moving this permission and causing the store to hang up, they have to be reluctant to reload, so everyone must pay attention to the operation, you must be very careful in deleting the file, do not delete it permanently.) Br>
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.
(Note: This step can be clicked to select the management user just added to click output, then check the replacement sub-container, and finally click OK.)
3. Ok, Win8 application file The folder is blocked again~
Basically using Win8 for a period of time, after the above processing, your system disk will release a few hundred megabytes of space, if there are a large number of applications and use frequently, you can release several G! Win8 applications are very space-consuming!
