If you don’t want Windows upgrades, move to Linux or a Mac. Windows upgrades are mainly designed to keep you safe online. If you can’t figure out Windows 10, you won’t stand a chance against a scammer or adware or ransomware.
Or if you just can’t stand the execrable Metro GUI, install Classic Shell (free) and it will work like Windows 7 and you’ll never see that crap again.
Never had a problem when I had XP or 7. But, ever since I started using Windows 10, nothing but problems with scammers and ransomeware! Had to pay twice to get the sh*t removed!
