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. We highly recommend it! Windows 7 Users: Please note that some reviews of this software indicate that it doesn't work with Windows 7. However, we've tested the latest version 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.
