Windows Product Key Finder Pro is an extraordinarily easy-to-use free key finder program. If you're ready to reinstall Microsoft Windows or Microsoft Office but you can't find your product key, Windows Product Key Finder Pro can extract it from the Windows Registry instantly.

There's nothing at all fancy about Windows Product Key Finder Pro which is one of the reasons I like it so much. There are no menu options or unrelated features like with some other programs that find software serial numbers and product keys.

Important: Please read my Key Finder Programs FAQ for more information on key finder programs in general.

My Thoughts on Windows Product Key Finder Pro

Windows Product Key Finder Pro is an excellent choice among the many free key finder utilities available. It's a quick download and easy to use. The product key (a.k.a. CD key, serial number, or installation key) is immediately displayed for your Windows operating system and Microsoft Office, if installed.

Windows Product Key Finder Pro does not find serial numbers and product keys for any other software than those titles listed above. While I have this listed as a con above, KeyFinder Pro does not claim to find other installation keys so I can't really hold it against the program. However, compared to other products that find product keys, this is something it lacks.

There may be no advanced features like activation backup or unrelated "cool" features like a password generator (try RockXP) but Windows Product Key Finder Pro still does what it's supposed to do perfectly - it shows you your product key. Plain and simple.

During setup, Windows Product Key Finder Pro installs a few other programs without your consent, which is very annoying because you must then remove them manually if you don't wish to use them.

Windows Product Key Finder Pro isn't a big bag of tricks. It does one thing - for free - in a small, simple package. I like a program that doesn't try to stand out from the crowd by its shear number of crazy features that rarely get used.

I absolutely recommend Windows Product Key Finder Pro to anyone needing to dig up that lost Windows or Office product key.

Didn't find what you were looking for with Windows Product Key Finder Pro?

If Windows Product Key Finder Pro didn't find a serial number you were after, just try another free key finder program or maybe even a premium key finder tool.
