Questions: Technology & Internet

I've had my gaming laptop since January 2020 and the past half year, it's been bugging out on me and slowing down in all sorts of ways. I can't exactly afford to buy a system that would surpass my current PC in all metrics, since that's exactly what I'd need and want in order to fulfill my wants in gaming and content creation, along with my needs in programming and AI (for my startups). I was thinking maybe instead of reinstalling Windows 10 and thus having reinstall all third party software, how about I switch over to Windows 11 before the security updates of 10 are discontinued and not have to reinstall anything?

I am aware that certain programs will probably either stop working unless I rely on extreme configs, mods, workarounds, etc., and also the new GUI will piss me off and also make me more happy too. I do have my stuff backed up through multiple cloud sources along with an external hard drive, but my internal SSDs are fine too. I would make the switch to Linux, but my PC uses Nvidia GPU and while I know that Proton, Wine, and DXVK exists, I don't wanna have to deal with that for now; not to mention the fact that my laptop has certain proprietary features like keyboard backlight and fan software that might not work in Linux.
