My Compaq was Winblows 98, and I had them upgrade me to 98SE. XP was better on the next machine I had, and it lasted me for a very long time, til I fried the motherboard. I got a small Winblows 7 desktop PC in the storage shed, a Winblows 8 laptop I seldom use, and a Winblows 10 laptop that won't let me use it.
I used to rebuild desktop PCs and sell them. Then, they changed everything so much that the newer ones are pretty much disposable. I still miss XP. I used to be able to hack a virus right out of my own hard drive.
