Today is a good day to drop windows. There are plenty of nice alternatives, do not delay if you don't want nasty surprises, use Linux:
https://distrowatch.com/Of course, as I explained elsewhere, your leisure activities and your money should be separate. So if you insist in keeping a "windows gaming computer", at least install Linux in another one and keep your serious stuff there.
this is a very common misunderstanding that people think if they use Linux they will magically be safe. but that is not the case at all. the only difference between Windows and Linux that makes Linus safe
r is that Linux is open source and when security holes are found in it, they are patched fast while Windows security holes take a long time to be patched and Microsoft usually leaves some backdoors intentionally.
otherwise if you want to be safe to you have to use
cold storage and it doesn't make much of a difference what OS you use for it then.
