Don't Forget Your Keys
If you've lost your software installation code, CD key, or serial number, you'll love this Keyfinder tool. Simply download and run this utility, and it will automatically search for key codes found in your registry. In fact, even if you cannot boot into Windows, it is still possible to recover keys (see documentation for details).
Conclusion
This is a very straightforward program, and it does exactly what it claims to do. If you are trying to recover your Windows Product Key, this is a great place to start. Lost your software packaging, and need to reinstall? Even if you've already uninstalled the program, it's possible that the key still remains in your registry. We especially like the fact that this tool works for many different applications and games, not simply Microsoft Windows and Office—it found many more keys than we expected.
