Linux

Whatever beginner friendly distro you choose, I suggest you use it as if you were a grandma, especially if you have experience in troubleshooting Windows. It's natural to try to find the solution to a problem by doing a Google search, but first of all Linux changes quickly, so solutions that are older than 2 years may be outdated, over 5 years they likely are, and they may apply to different distros than yours, so be careful. Always check your DE's settings app first, those have gotten really good in the last few years.
Don't be afraid to ask in chatrooms if your distro has any, the myth of the rude Linux community is just that, a myth.
