The Windows 11 Start menu has been the most significant change to Windows in recent times. It comes with tons of additional features while making the GUI a tad bit simpler to find most items on your PC. The ability to center the same on your desktop has also been a boon for many users.

Sadly it seems that a recent update issued by Microsoft breaks the Start menu for many users. If you’re in the same boat and unable to use the Start menu after a recent update then here’s all you need to know about it.
