You are on Lemmy, which shows that you weren't deterred from learning about all the instances and stuff. So you are open to learning. So I would slowly dip my toes into Linux if there's no Windows specific software you absolutely depend on.
I would suggest Linux Mint: https://www.linuxmint.com/
This is beginner friendly and for the most part can be operated pretty much like Windows. Slowly, you will get used to typing in commands into the terminal to maybe update and upgrade your system. Online instructions to install programs are widly available to find (install [program] on ubuntu/debian) can be easy since it's based off of ubuntu/debian
Now, if you really want to use windows for whatever reason, everything is already on the massgrave website for you to read and install.

Linux will show you how to troubleshoot and use your computer more efficiently and not spy on you.
Windows will simultaneously spy on you and still shit itself so you'll still have to learn to troubleshoot. Give it a few years, and Windows will enshitify further. You're just delaying the inevitable.
