Recover Your Lost Product Key

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.

Not uncommon, especially if you’re rebuilding a system on someone else’s behalf. But over at NirSoft, among the many, many useful utilities is one called ProduKey.

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 Zip64-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.
