Windows 7 oem VS upgrade edition

OEMs are full versions of the OS. They do not require a previous version of the OS to already be installed on the Hard Drive. Upgrades, on the other hand, do require a previous version of Windows Installed.

If you have a previous version of Windows available to you, You could install that version, purchase the cheaper upgrade, and then install the upgrade over the previous OS. A lot of work, but if it saves you $40, it might be worth it.

My recommendation is to Google that very question.

You might find the answer you're looking for...

How very clever if you. This matter appears much more complicated than one would hope, so does anyone have any experience in this matter? Has anyone installed an upgrade version of Windows 7 on a virgin hard drive? I'm a little dubious of regedit.exe and product key hocus-pocus.
