Windows 10 Start menu not working

[Chris-ITK]

Hello to all,

for a few weeks, several computers with Windows 10 21H1 or 21H2 have problems with the start menu, from one day to the next, the menu does not work anymore.
It works on another session.

I have already tried several things:
Rebuild the start menu with a PowerShell command <- without success.
Update to the latest possible version <- without success.
Run two commands to see if there were any corrupted system files (dism.exe or sfc /scannow) <- without success.

in eventviewer I can see that the StartMenuExperienceHost.exe has crashed every time I click on the start menu.

In short after testing everything I could find on Google or on Microsoft forums, I would still like to have your opinion, especially since it is very random.

The only two solutions found for the moment are to create a new profile (not practical) or to upgrade to Windows 11 (not very stable).

Would you have an idea or an efficient solution that would avoid the two solutions that sometimes take a lot of time?

Kind regards

Hi @Chris-ITK ,

had some similar issue, but ended up creating new user. :(

Have you tried to check in safe mode?

One machine did actually responded on the powershell script below:

It will actually "rebuild" Start menu.

Also check if you have anything in Applocker c:\windows\system32\applocker 

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Hello @Adin_Calkic

No, I didn't test the start menu in safe mode.

I already tried that PowerShell command without success.

Thank you for your advice.

Kind regards
