Installing Windows Vista without system restore CD with OEM key (ie: from underside of my laptop)
I am trying to do a clean reinstall of Windows 7 professional edition, but I can't find the original disk or the recovery disk. However I do have the CD key. Is there a way I can get Microsoft to send me a CD/download an image of Windows 7 to reinstall from, or is there an image of the OS already saved on the system (I have a lenovo thinkpad w500 that came with Windows 7 professional edition).
