Windows Insiders in the Dev and Beta channels are experiencing massive Start and the Taskbar stability problems in the newest builds. But Microsoft has issued some fixes and workarounds.
“We’re investigating reports across our Dev and Beta Channels that Start and Taskbar are unresponsive and Settings and other areas of the OS won’t load,” the Windows Insider Twitter account revealed yesterday, and then added, “Thank you again for your patience #WindowsInsiders – If you were impacted by this issue, you can use the steps added to the top of these blog posts to get back into a working state on your PC.”
The account linked back to the original posts announcing Windows 11 Insider Preview builds 22000.176 (for the Beta channel) and 22449 (for the Dev channel), respectively. But the instructions are the same in both cases: You need to open Task Manager (ironically now harder to do in Windows 11), run CMD (and not the Terminal, also curious), and delete a specific Registry key; note that the PC will reboot immediately.
And that should do it.
