Windows Product Key Viewer is a small, easy-to-install and, most importantly, effective tool for reading the product key installed on your Windows computer. After starting, the program displays a window where you can find the aforementioned key used during the installation of the operating environment, as well as many other useful information. These include the system version, the name of the logged in user, the date of Windows installation, total system operation time, product ID number or buildu label.

Windows Product Key Viewer supports Windows operating systems in versions 95, 98, ME, NT, 2000, 2003, XP, Vista, 7, 8, 2008, 10 (both 32-bit and 64-bit versions). It also allows you to export all these data to a text file.
