Sometimes, after you update Windows on your PC, some Microsoft Store apps may stop working and display greyed-out icons in the Start Menu. This bug primarily targets common utility apps, and the effect is that their app tile and icon appear greyed out. When you click on them, they immediately shut down.

4] Update your graphics card driver

An outdated graphics card driver can also cause this error to occur.
- Open the Run dialog box and type ‘dxdiag’, this will open the DirectX Diagnostic Tool which we’ll use to make a note of your computer’s graphics card
- Have a look at your computer’s model and the graphics card it uses.
- Then, visit the official website of your graphic card’s manufacturer and download the latest one available
- Once downloaded, install the driver.
5] Re-register Microsoft Store on your PC
If the issue lies with the credentials of your Windows Store, you can give re-registering it a shot too. Here’s how you can do that.
- Search for PowerShell in the Taskbar search pane and open it to run as the administrator
- Type the following command and press enter:
Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
- The process will take some time to complete so wait a while and once done, open the Run dialog box
- Here, type ‘wsreset.exe’ and hit Enter. The process will finish when your Windows Store will be reset and this will do that.
