Hi all, my work laptop got upgraded to Windows 11 recently from Windows 10 (IE. I didnt' choose this!)

I upgraded my Start 8 license and installed Start 11 because I didn't like the lack of options customizing the taskbar in Windows. Why would they not make the taskbar features and options like-for-like with Windows 10?? Surely that would be low hanging fruit for Microsoft to make sure people were satisfied with as much of the new OS as possible. 

Anyway, I immediately noticed very sluggish performance in Windows and all applications after installing Start 11. I tolerated it for a week before uninstalling Start 11 to see if that was the issue. Turns out it was the issue. Windows and all applications are fine now. I'm running four monitors so maybe that doesn't help. I didn't try paricularly hard, but has anyone encountered this and managed to resolve it? 

I'd be happy to reinstall it and try some troubleshooting if anyone has any suggestions, or if there is a tool I can run and send logs back or something.
