Just one version of Windows 8?

Just to rub salt into the wound, as if I did not think W8 was the worse piece of software I've ever used.

The one program it has to run, the only job I've asked of it ever, the program it's been running for a week. Well today it's decided it's not compatible, all the other days it was compatible now it's not.

Total utter {rap, I've got an old Amiga somewhere that was better than this.

I can't believe anyone rates this pile of poo as good.
