Reinstalling Windows and your software can be a tedious experience, and we're not just talking about having to snooze through a succession of glacial progress bars. The real pain comes in having to track down all your product keys, locating old installation CDs, the emails, or whatever bit of paper they arrived on originally.

MyKeyFinder can speed up the process by assembling all your keys in one place. Just run it on a PC, wait as it scans your installed applications, then print its list of licences, save them as a PDF file or copy them to the clipboard for use elsewhere.

The developer doesn't have a central list of the applications MyKeyFinder supports, but we found it returned keys for Windows, Microsoft Office, and products by CyberLink, Adobe, Corel, Nero, AVG, VMware and more.

If this isn't enough, and you already know a Registry key which contains a product licence, then you can add this and it'll be included in future reports.

In addition, if MyKeyFinder keeps displaying incorrect information then simply add that key to the "Blacklist" and it won't appear again.

Please note, you must provide your email address to register and activate the program, but otherwise it will begin to work immediately, no "confirmation emails" or other steps are required.
