I'm just like you Zim.
I really liked XP Pro. I put SP 2 into it and stopped there. No more downloads and crap from MSFT going into it.
Worked fine..
When msft needed to make more money and started coming out with the newer windows software I knew eventually I would need to upgrade sometime. Windows 7 Pro is really nice. Not one blue or black screen, so stability is really great.
Windows 8 was a nightmare for anyone.
Windows 10? I have that on my new HP laptop and I am still trying to get accustomed to it. I don't take easily to change and I can re-install this windows 7 program on anyting if I need to. I can still do that with XP and I have SP 2 slipstreamed onto it.
Call it 'Back to the future" .
Take care!
