Sounds like your organizations Windows 11 image is bloated and or your adnin didn't set much in the way of group policy. It could also be one of those shit corporate security products eating up resources.

Talk to your admins to see if you can speed it up. One of my work machines has a 8th gen Intel i5 with 48gb of ram and it is quick and snappy. I got permission to strip out Onedrive and some other junk which helped a lot. I also disabled all of the startup apps.
