CheckWindowsGenuine is a straightforward portable app designed to reveal if your Windows license is genuine.
You can run it from the command line or by double-clicking the EXE after unpacking. It quickly gathers the pertinent data and displays information for the type of license, activation status, and the length of the active period if the license used is not permanent.
CheckWindowsGenuine will come in handy when purchasing a machine so you can verify whether or not the included Windows license is original. Having this information can save you some money in the long run as OEM software is generally reflected in the price. It can also save you from buying a machine with pirated software onboard. A great option for ensuring that your purchase is as advertised.
