And the old control panel: Some users reported that the upgrade to Windows 11 did not go as smoothly as they would like. In some cases, the old control panel and Start menu remain after the update. They also don't work well. Discuss
Complaints about this have appeared on Reddit and on the Microsoft support forum. Users say that they used the official utility “Windows 11 Setup Assistant” to update the operating system. However, this did not save them from bugs. Users have not seen the much-vaunted new Start menu, and they cannot fully use the old one.
Microsoft has not yet resolved this issue. Affected users have to wait for the appropriate patch or remove the latest update. There is also information that you can create a new account with administrator rights.
