Solved I lost my MS Win7 Product Key

I can't find my Win7 DVD & Key and I need to re-install Windows7-

If I retrieve my MS Win7 Product Key (with Magic Jelly Bean Key finder), can I use my brothers

retail/boxed Windows 7 installation disk and enter 'my' legal Product Key?

Thanks-

Hi,

Yes, I belive you can, as long as its a retail version of Windows, and not an OEM version.

Please wait until someone more senior has confirmed my reply before proceeding.

Golden is correct. You can use any Win7 retail installer for the same version to reinstall with your own Product Key, whether it's the Product Key which comes in the retail box or on the COA sticker on a factory OEM machine.

I would double check the installed key using Belarc Advisor which will also give you a complete audit of all of your hardware and installed software along with all Product Keys. Belarc Advisor - Free software downloads and software reviews - CNET Download.com

Here are tips for getting a perfect reinstall using this method: Reinstalling Windows 7.
In the first paragraph I deal with how to unlock all versions in the retail installer in case the DVD isn't the same version.

If both the versions match, it's fine using an OEM disk to install - it's the key that counts.

If it is an OEM disc though, you may have to ring MS to activate since OEM discs are meant for "one off/one machine" automatic activations.

EDIT: Ninja'ed

Thanks everyone!
