ProduKey

So,you forgot which key you used to install and activate.

ProduKey is a small utility that displays the ProductID and the CD-Key of Microsoft Office (Microsoft Office 2003, Microsoft Office 2007), Windows (Including Windows 7 and Windows Vista, Exchange Server, and SQL Server installed on your computer.

It's free!:biggrin:

Thanks for the tip! Wish I'd known about that a year or two ago when my mom's desktop crapped out. I hated being on the phone with the PC retailer and Microsoft trying to get a new key.
