PKeyMaster is an open-source application developed by NTriver.org for checking and analyzing Microsoft 365 and Windows product keys. It is intended for users who find a key and want to learn more about it, and it mainly addresses someone who manages many licenses and needs to sort, verify, and audit them. The program validates existing keys; it does not generate anything or participate in piracy. It can check keys across a long history of Windows, including very old systems such as Windows 95.

Users can launch PKeyMaster through PowerShell or other terminals without knowing commands. Interaction is direct: paste a key or load the corresponding key file. For an invalid key, the application reports that the license is not valid. For a genuine Windows product key, it reports that the key is valid, the Windows edition it belongs to, and the license type, such as OEM.

PKeyMaster supports advanced key scanning. It can process many keys in a list and run them through the same Microsoft licensing checks automatically. This shows whether each key is accepted and what type of license it is, including OEM, MAK, and volume licenses.

The application can also check keys through the old phone activation system, IID to CID. This method is offered for backup situations where online activation fails, or for older systems and offline environments.

PKeyMaster version 0.4 is listed under Business::Office Suites & Tools. It is available for Windows 11, Windows 10 32/64 bit, Windows 8 32/64 bit, Windows 7 32/64 bit, and Windows Vista 32/64 bit.
