Since my most recent Windows 10 update to version 21H1 with I cannot open the Context Menu (right click) on the Windows 10 Taskbar apps.

This is specifically on the apps themselves and not the Task Tray, Start Menu, Cortana, Search or Task View -- all these worked correctly.

Just like some other questions, as some of the comments addressed on these, their workarounds (such as restarting explorer, restarting the tile service) and answers (such as fixing Local Group Policy for context menu permissions on the Taskbar) did not fix the issue. This also displays no errors at all.

It turns out that the reason my Context Menu was broken in the latest update was due to StartIsBack not being compatible with Windows updates after the 21H1 installation before version SIB 2.9.11.

SIB had not recognised it needed to update yet so I was still on 2.9.9.

I simply updated to 2.9.11 manually by downloading it from the website and now the issue is fixed and I didn't need to restart Explorer, my PC or any tile servers.


When a variety of other solutions did not work, Fix the right-click Context Menu on the Start Menu and Taskbar through PowerShell once fixed broken right-click context menus in a Windows 10 Home Version 21H1 OS build 19043.1083 Experience Windows Feature Experience Pack 120.2212.3530.0 task bar.

This solution calls for running PowerShell as Administrator, and then running the following command:

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

The command runs for quite a long time and error messages may be ignored.

After following these instructions, right-click context menus in the task bar started working again (reboot not needed).
