I put Windows 10 on my Brother's Laptop.
He Hated it so I pressed the " magic button " to restore it back to windows 8 as it came out of the shop.
Guess what . . . . Windows 10 had screwed that up so it took me ages to get it running on windows 8 again.
Let me see . . . . . . Microsoft?. . . . . . .Free?
They must be up to something !
I'll stay with Windows 7 thanks.
