Win XP has newly found vulnerabilities, and since it is no longer supported with updates you might want to rethink your unwillingness to upgrade.
Windows 7 was maybe the most solid product that MS ever made.
I resisted Win 8 because I’m a curmudgeon. I did finally do the Win10 upgrade when I got a new laptop. I have to say... It’s pretty good. I’m not a fan of the auto updates, but everything else is pretty freaking amazing. I’m not sure this system -can- crash. I’ve had some software seriously misbehave and still not kill the system. Games, mostly. Anyway...
Win 10 doesn’t suck. Saying that as a curmudgeon still ran some MSDOS systems well into the 2000s.
DOS 6.2 was pretty darn solid ;^)
