Another one for your tool kit… When you find yourself rebuilding a corrupt system, or just carrying out a straight-out rebuild, you’ve got all the install CDs, verified backups of your important data, found the storage driver disks, and… you can’t find the product key.
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.
There are a few different versions of the app available for download on the site, including 32-bit Zip, 64-bit Zip, and full installer versions – just download and run on your system of choice, and you’ll be able to ‘recover’ the product key that was used during installation of the operating system.
Taking it a little step further, I highly recommend you grap a copy of the NirLauncher, which is a complete package of all the NirSoft portable freeware utilities which you can just unpack to your local drive or favourite USB stick – you can even integrate the SysInternals Suite into the NirLauncher using the additional downloads available on the site.
