My first pc was on xp in 2002.
Next was vista , that was a nightmare , its origonal name was longhorn whilst it was under development and it took so long to release that they changed its name to vista in the hope that users would forget the word longhorn. It was an awful operating system and had so many performance logs that if you were paranoid you could actually convince yourself your pc was faulty.
At the same time i was using vista i got a spare pc with windows 7 on it , the pc shop described 7 as vista with all the rubbish taken out , after booting it up vista became my spare pc.
Before buying a pc with windows 10 on it i put the free version on a spare pc so i could get a feel of how it worked.
I eventually got a custom built games rig with windows 10 on it , it only came with the operating system installed so i was free of bloatware and trial software.
I currently have 2 desktops and a laptop all running windows 10 and can say in all honesty that i have never had a problem with any of them , unlike some people i think 10 is the best.
FOOTNOTE even when xp was outdated i kept it as a spare because it came with a free copying program called dx now , it could handle anything , that is until you had to register games id codes online .
