Begone, weird new context menu!

The good thing about it, is that it includes an "UnDo" file as well so you can reverse the registry edit.
So it might be helpful to recover from that.
Additionally, I've used both StartAllBack and Start11
Both were easily uninstalled and my computer returned to Windows 11 default condition.
I am also missing Search on the taskbar but its back with OpenShell
I've no experience with that except back when it was still called "ClassicShell", so I don't know how to back out of that.
I would think that now would be a good time to get your OS back to original condition rather than heaping on layer after layer of hacks and shell overlays.
After which you might have a look at this
If you are looking for a free way to turn Windows 11 back into Windows 10 a bit, with regards to the taskbar and File Explorer at least, Explorer Patcher will do this for you. Bye bye, useless menus!

Super easy to install and just as easily uninstalled.
It's all I use currently.
