As for your question, Agar, "MMGA Server" in Windows 11 is a legitimate component of the operating system related to the Microsoft Management Console. It is responsible for various administrative and management tasks.
The MMGA Server doesn't directly track your location. However, some apps or services controlled through the Microsoft Management Console might need location data to work properly. For instance, a system management tool could use your location to provide updates or settings that are specific to your region.
Check the privacy settings in Windows 11 to see which apps are allowed to access your location. If you're not comfortable with any app having access, you can remove its permission.
