Windows 11 Insider Preview update has some problems Taskbar is "unresponsive" (solution available)

On September 2 (US Pacific Daylight Time), Microsoft announced that the taskbar and desktop (Explorer.exe) do not respond in the latest update of the "Windows 11 Insider Program", a preliminary test program for the new OS "Windows 11". We announced that there may be problems. If this problem occurs, it can be resolved by deleting a part of the registry.

This bug is due to "Build 22000.176", which began distribution on the Beta (β) channel and Release Preview channel from September 2nd (US Pacific Daylight Time), It may occur in "Build 22449", which has started distribution on the Dev channel.

Build 22000.176 is positioned as a preview of the production version, allowing you to try out all the features that will be implemented in the production version, which is scheduled to be released on October 2nd.

In environments where this problem occurs, it is possible to upgrade to this build. After applying the update program, the taskbar and desktop (Explorer.exe) stop responding immediately after login. Microsoft is already aware of the problem, as many users rolled back the update.

If a problem occurs, log in and follow the steps below to get it to work properly.

This solution edits the "registry file" that stores Windows settings. Be careful not to change the setting of unnecessary parts.

For those who are not good at command prompt (uneasy), please try the following procedure after proceeding to the fifth step.
