Hm… things that are run automatically on startup of the OS might be quite individual on each machine.
Something i use on my Windows machines regularly is the small software “O&O Shutp 10” (also suitable for Win 11), which disables a lot of services and adjusts a lot of settings, which I don’t want to have - mainly because of privacy reasons, but I think having fewer tasks running in the background might also save a bit of CPU load…
Maybe if you show us a screenshot of your actual autorun list, there is a chance of giving you better advice.
