Used GBS Win Key Viewer/Changer for Windows?

Editors’ Review

Though it's a bit plain in design, this application promptly reveals Windows and Office keys. Despite the absence of a help file, the program has a standard interface that's easy-to-understand. GBS Win Key Viewer/Changer immediately displays the product key of your Windows and Office systems but conceals the last five characters and restricts key changes in the demo version. It does allow you to change the registered owner and organization name. This software offers a quick fix for anyone needing product-key information.

What’s new in version 1.0

The full version includes an Exchange and SQL Key code Viewer.
