How to Reveal Your Windows Product Key in All Current Versions of Windows

Here’s a situation to be avoided—for one reason or the other you have to reinstall the Windows operating system but you discover that you don’t know the product key. To avoid this predicament, retrieve the key now, print it out and put it somewhere safe.

There are numerous programs that will retrieve the Windows product key but many will not work on 64-bit systems. Some favorites like Belarc Advisor and System Information for Windows are very useful for providing all sorts of information but are overkill if all you want is the Windows key.

NirSoft ProduKey

Produkey from Nirsoft is a portable utility that requires no installation and can be run from a USB key. It works in all current versions of Windows including Windows 8. It does have the restriction that it does not work for Microsoft volume licenses in Windows 7 and 8 or certain OEM keys. There are both 32- and 64-bit versions. It also provides the product key for Microsoft Office. The description and download are at this link. The download link is near the bottom of the page.

Windows Product Key Viewer

For a quick and portable little program that works in 32 and 64-bit versions of Windows XP, Vista, 7,  and 8, try Windows Product Key Viewer from RJL Software.   It works from a USB key and is only 509 KB. It is free but it does put up a little flash screen for a second or two when you close the application. It only does one thing but it’s quick and easy to use. It has an option to print the key or save it to a text file. Requires administrator privileges in Windows Vista/7/8.

Magical Jelly Bean Keyfinder

Another little portable program to consider is Magical Jelly Bean Keyfinder. This program has been around for years but it has been updated to handle Windows 7 and 64-bits. However, it did not give the correct product key whwn I tried it in Windows 8. It tacked an extra letter on the front of the key. It's another application that puts up a splash screen when you close it.

Here's a very simple way to find your Windows key. Download Belarc Advisor, a free system analysis app that's been around forever. Once it loads look to the upper left corner of the GUI where the words "Software Licenses" are highlighted. When you click on that link you will immediately see your Windows key displayed along with some other keys to software you may have on your computer.
