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. You can view this information for your current running operating system, or for another operating system/computer - by using command-line options. This utility can be useful if you lost the product key of your Windows/Office, and you want to reinstall it on your computer.

Changelog:
When the product key is not stored in the Registry (like in volume licenses of Windows 7), ProduKey will display 'Product key was not found' instead of wrong 'BBBBB-BBBBB-BBBBB-BBBBB-BBBBB' key
