Fix: Start Menu Not Responding / Can't Log Into Office Apps

Your Windows Start menu is not responding?
Since the beginning of this week, we’ve also been getting a lot of reports about Start menus that don’t work and users who can’t log into the Office applications anymore.
The problem can be traced back to an update from ClickShare, which uses the Outlook API for the calendar integration.

The problem already came up last year and was documented very well by Rudy Ooms: Startmenu not responding | Broken Store Apps | 0xc000027b (call4cloud.nl)
He also kept extending the solution and worked out the root cause.
In some support cases, though, not everything worked completely, which is why I put together a video guide and four PowerShell scripts that need to be run in the user and admin context.

Fix: Start menu not responding

1. Log in on the device with the affected user (best done via remote management)
2. Open two PowerShell windows and do not minimize them!
   • open the first PowerShell terminal as User
   • run the second PowerShell terminal as Administrator
3. Open Task Manager
4. Stop the “Windows Explorer” process
5. Copy the content of the first script into the User PowerShell window and press [Enter]
   1_ClickShare-CalendarIntegration_asUser.ps1
6. Copy the content of the first script into the User PowerShell window and press [Enter]
   2_FixUserShellFolderPermissions_asUser.ps1
7. Copy the content of the second script into the Administrator PowerShell window and press [Enter]
   3_StartMenuFIX_asAdmin.ps1
8. Copy the content of the first script into the User PowerShell window and press [Enter]
   4_SearchFix_asUser.ps1
9. Start the “explorer.exe” process in Task Manager
10. Now everything should work as expected again 🥳
