Windows Key Finder Pro

KeyFinder Pro is a lightweight and portable application that retrieves lost or forgotten serial numbers to Windows and Microsoft Office products. It can be easily used by novices, since it doesn't include configurable parameters.

Since installation is not a prerequisite, you can just drop the executable file anywhere on the hard disk and click it to run. It is also possible to move KeyFinder Pro to a USB flash drive or similar storage unit, in order to run it on any workstation seamlessly and without prior installers.

An important aspect to keep in mind is that the app does not add new entries to the Windows registry, Start menu or any other area of the computer. A basic file deletion is enough to remove it.

The interface is made from a single window with few options. The serial keys for your Microsoft products is automatically loaded at startup, and you can copy them to the Clipboard, save them to a plain text document, as well as print them. There are no other notable options available through this utility.

KeyFinder Pro is very light on the system resources, running on a minimum amount of CPU and RAM. It doesn't affect system performance, hang, crash or show error dialogs. We have not come across any issues throughout our evaluation. Thanks to its intuitive layout and overall simplicity, this straightforward application is appealing to all users.
