What’s guidgen.exe (Microsoft ® GUIDGEN Application)? Is it safe or a virus?

Guidgen.exe is a utility program developed by Microsoft Corporation used for generating globally unique identifiers (GUIDs) or universally unique identifiers (UUIDs).

These identifiers are 128-bit numbers used in software development for uniquely identifying objects or components in a system. The program allows developers to quickly and easily generate GUIDs for use in their applications.

Have you ever installed Shareware, then uninstalled it, then reinstalled it and the free trial won't work anymore? That's probably because the developer created a GUID for your PC and the developer knows your specific PC already used the free trial.

Below are 4 simple steps you can take to see if the guidgen.exe process is safe or malware.
