When you need to check a product key, just fire up the app and it will very quickly scan your computer for any support software. There is no need to install the software, so it is a great utility to have stashed away on a USB drive ready for when you want to reinstall Windows on your own computer or you are called on to help someone else. There are two different versions available, one for 32-bit versions of Windows and one for 64-bit users, so make sure you have the correct one downloaded. The only requirement is that you already have the software installed – the program cannot be used, for example, to determine the product key for Office based on its setup files. This ingenious little tool can be used to find out the product keys for various versions of Microsoft Office and Windows, in addition to Exchange Server and SQL Server. All of this could come to an end with ProduKey. Depending on how you bought your software this could mean seeking out the box it came in, looking on the CD or DVD label, or searching through your inbox for a purchase receipt. When the time comes to install your software after reinstalling Windows you will need to endure the thankless task of hunting down all of the necessary product keys.
