Solve the problem that all applications in Windows 8.1 (Modern App) cannot be opened (flash back), 8.1app

I have encountered this problem on three computers. The problem is that all apps installed in the App Store cannot be opened, including the App Store itself. After clicking the application on the Start interface, the Logo of the application flashed, and then disappeared, returning to the start interface.
When you view the system application logs, the following message is displayed (in English ):

Activation of app Microsoft. ZuneVideo_8wekyb3d8bbwe! Microsoft. ZuneVideo failed with error: This app does not support the contract specified or is not installed. See the Microsoft-Windows-TWinUI/Operational log for additional information.

Follow the prompts to open Microsoft-Windows-TWinUI/Operational and see:

The description for Event ID 2095 from source Microsoft-Windows-Immersive-Shell cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.If the event originated on another computer, the display information had to be saved with the event.The following information was included with the event: Microsoft.ZuneVideo_8wekyb3d8bbwe!Microsoft.ZuneVideo2147745793The message id for the desired message could not be found

I spent two hours searching for N more materials on the Internet, and finally found a solution on the Microsoft official website. Next I will combine various useful information and translate it briefly.

First, the first step is to download the official bug fix tool ,. After downloading and running Next all the way, if you are lucky, you can solve all the problems. If you are lucky, you can at least run the App Store itself.

Next, if you have changed the application-Related File System or registry, follow this article to fix the permission issue.
The following permissions are for the "All Application Packages" group.
File System permissions:

• Program Files-Read, Read and Execute, List folder Contents
• Windows-Read, Read and Execute, List folder Contents
• Users \ <userName> \ AppData \ Local \ Microsoft \ Windows \ WER-Special Permissions (List folder/read data, Create Folders/Append Data)

Registry permission (Read ):

• HKEY_CLASSES_ROOT
• HKEY_LOCAL_MACHINE \ Drivers
• HKEY_LOCAL_MACHINE \ HARDWARE
• HKEY_LOCAL_MACHINE \ SAM
• HKEY_LOCAL_MACHINE \ SOFTWARE
• HKEY_LOCAL_MACHINE \ SYSTEM
• HKEY_USERS

The above cannot be solved, so we should read this article.

It solves this problem:

A. Manually fix problems that cannot be opened by the App Store. (The Official Repair Tool downloaded in step 1 can solve this problem. The app store can open it and skip this step .)

B. Repair other system apps

1. Run the following command in the Powershell window started as an administrator:(Get-ChildItem "HKLM: SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Appx \ AppxAllUserStore \ InboxApplications") | Get-ItemProperty). Path | Add-AppxPackage-Register-DisableDevelopmentMode

C. Fix other third-party apps

1. Run wmic useraccount get "name, sid" in the Powershell window. Find the row of your account and remember the SID column.
2. Find and delete it in the Registry (Replace [UserSID] with the one in step 1): HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Appx \ AppxAllUserStore \ [UserSID]

Restart the computer and open the App after the restart. If the application is unavailable, wait for a while.
