Windows 7: Accidentally installed WIN7PRO, have premium key.

Windows 7 Professional x64
Accidentally installed WIN7PRO, have premium key.

So as the title says, I failed and installed professional. It wouldn't be a problem, but now I do not have the disk I used, and I have 14 days left to activate windows. I never activated it before right away, so I figured now would be a good time. THen I realized that I had installed professional, and not premium... FAIL.

So, what I was wondering, is there a way I can convert professional to premium, or somehow use this premium key? I'm trying to avoid having to re-install windows again, because in these 16 days, I've installed a lot of stuff including games, and I'd rather not have to lose them.

Any help is appreciated, thanks.

You'd need the installer and it's easier to just Clean Reinstall - Factory OEM Windows 7.

The installer for your licensed version printed on the COA sticker on laptop underside is provided in Step 1, with tool to burn to DVD or write to flash stick in Step 2.

Stick with the tools and methods in the tutorial and you'll get and keep a perfect install, the opposite of factory preinstalled Win7.
