You can just hear Steve Ballmer screaming:
"It's the last Windows you'll ever need!"
I am writing you all on XP. The best of the best, in its day.
I tried a win7 box five years ago. I hate that machine. My desktop is still the 15 year old XP.
The only things I like are Windows 10 boots up to the desktop in 30 seconds. The start menu is not bad but creating a simple shortcut from the Programs have you do extra steps.
Too many other annoying issues. I really hate Microsoft updating and changing the look and also the spying and soon the monthly charge for using Windows.
