The Chris Titus utility has worked very well for me. I used it to de-bloat Win 11 after I upgraded the OS last year.

I run Win 11 on an old tiny NUC PC that has Windows 10 before - now it does seem faster, is very stable and is not so annoying.

One thing: AFAIK you need to have the Windows 11 Pro version for the best de-bloating results.
