Microsoft has released new Windows 11 preview builds for both the Dev and Beta channels a few hours ago, and in addition to further polishing and optimizations, they also have a bug that wasn’t contained in the known issues at first.
This glitch causes the Start menu and also the taskbar being unresponsive, with Microsoft acknowledging the problem following the first users installed the preview builds and reporting it online.
“Recently, Windows Insiders both in the Dev and Beta Channels began reporting that Start and Taskbar were unresponsive and Settings along with other areas of the OS wouldn’t load. We quickly discovered an issue with a server-side deployment that went out to Insiders and canceled that deployment. Should you be impacted by this problem, you should use the next steps to obtain back to a working state on your computer,” the organization explained.
Microsoft has therefore released a workaround for that impacted devices, and applying it only takes a minute, because it just comes down to deleting a registry entry in the Task Manager.
How to fix the bug
Microsoft explains that users have to launch Task Manager by pressing CTRL + Alt + Del (given the taskbar and the Start menu are both unresponsive), and then click the “More details” option at the bottom of the screen.
Visit File > Run new task, after which type cmd to produce a Command Prompt window. Next, you need to paste the next command within the Command Prompt window you simply launched:
reg delete HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\IrisService /f && shutdown -r -t 0
Hit enter, watch for your computer to reboot, after which everything should be working correctly, with both the taskbar and also the Start menu to run as you’d expect these to run in the first place.
