Cntrl+Alt+Del for TaskManager to see what is running and using resources. It will be incomplete.
AMD 'experience' and Radeon and Edge and other crap might be running.

Start __ CMD (run as admin) __ then sfc /scannow in the box for a system file check and repair.

Win+R __ services.msc to control startup types.

gpedit.msc is a control for users but it seems Win11 won't allow accessing it right now. Not sure why.

I edited the registry to block Cortana, and Widgets start menu news feed, and Search from using web search instead of my computer.
So sick of Edge being forced on users(owners) using dirty tricks. When does "no" not mean no? Windows changed it back. Sigh.

I've used CPUID/CPU-Z and UserBenchmark (thx flipper) to test hardware speed. DriversCloud to update drivers.

Layman advice here.
