Microsoft PID Checker is a quick way to validate a Microsoft Product Key for MS Windows, MS Office, etc.



Windows is able to tell the genuine status of a program according to various details, such as product keys or digital signatures. These, however, can become messed up and lose validation with Windows. In this regard, Microsoft PID Checker comes as a small tool with which to validate Microsoft Product Keys for various components.

Taking everything into consideration, we can state that Microsoft PID Checker is a quick way to validate a Microsoft Product Key. It already contains a great deal of xrm-ms certificates, but you can also use it with custom PkeyConfig files.

Portable, no installation required.
