Microsoft offers a quick workaround after Insiders began experiencing unresponsive Start and Taskbar with the latest preview of Windows 11.

  • Microsoft server-side deployment causes Windows 11 to become unresponsive.
  • The problem occurred during the rollout of builds 22449 and 22000.176.
  • The workaround for Windows 11 users is to run a command to delete a specific Registry.

If you have a device enrolled in the Windows 11 Dev or Beta Channels of the Windows Insider Program, you probably noticed that during the last update to build 22449 and build 22000.176, the Start menu and Taskbar were unresponsive, and Settings and other elements of the OS were not loading.

According to Microsoft, this issue occurred because of a server-side deployment (which it’s not detailing) and canceled that deployment. In the case that you came across this problem, the company has issued a workaround to get Windows 11 back to normal.

In this guide, you will learn the steps to resolve the usability problems caused by the September 2 update for Windows 11. (See also this video tutorial in the Pureinfotech YouTube channel to fix this problem.)
