It's a quick download and it's very, very easy to use. The product key (also referred to as the CD key) is immediately displayed for your operating system. Winkeyfinder lets you print your product key, save it as a text file, or copy it to the clipboard to paste elsewhere for safe keeping - all from within the program! Advanced users will appreciate the capability to easily change user registration information and also change the product key (Windows XP and Office 2000 only). Of course, you can change your Windows XP key manually if you'd rather not use Winkeyfinder for that purpose. You may not use Winkeyfinder every day, but it does its job when you need it to. I highly recommend Winkeyfinder! Windows 7 Users: Please note that some User Reviews below indicate that this program does not work with Windows 7. However, I have personally tested the latest version of Winkeyfinder on a retail version of Windows 7 Ultimate (64-bit), and several other Windows 7 versions, and it found the correct product key each time without a problem. Also, some users have indicated that this review of the free Winkeyfinder is in some way a means to persuade you to purchase another program. Quite the contrary. This program is completely free and there are other free key finders as well, all which work as well or better than the ones that charge. Download Winkeyfinder Didn't find what you were looking for with Winkeyfinder? Try another free key finder program or maybe even a premium key finder tool. Another key finder might be able to find the key for the specific program you're after.
