You are not “barely computer literate”. Most people have no idea how to put a OS installer on a flash drive and boot from it. If you know how to format your laptop and reinstall Windows, you know how to install Linux. Install any beginner distro (Ubuntu, Linux Mint, etc) and have fun. Google is your friend if you find any issues. There are a lot of resources online to help you.

If you want to play games or use any specific Windows-only software you may have to do some research, but if just for browsing the web you will most probably have a good time. Don’t be afraid to try and learn.

If you want to remove bloat, you can use this software. It doesn’t require root. Just be careful to not disable important system apps otherwise you can make your tablet unusable and will have to find a way to go to recovery and factory reset.

I used it on a friend’s cheap Chinese phone and it removed a lot of stuff. The phone was much better after that, but of course, be extra careful to not remove important stuff.

Good luck!

A friend once ordered a box of 50 to share with students from university and they delivered to the other side of the world not even charging shipping!
