Erm - a person I know, had a laptop, onto which he had loaded one of the Beta Versions of Windows 7; when he turned it on last weekend, a warning popped up on screen telling him that the beta version had now expired etc. He still had the restore Windows Vista CD that came with the laptop originally so set about restoring the machine. Unknown to him, he actually put an OEM Windows 7 64-bit restore CD that he had received with his main PC into the laptop; it runs perfectly, both validated as legitimate copies of Windows 7.
