User Groups and Access Permissions

By default, all authenticated users who log on to the system can control, configure, and run the RTX Subsystem and RTSS applications, even if they are not computer or domain administrators. System administrators can control access to the RTX resources by configuring members of the RTXAdministrators and RTXUsers groups:

RTXAdministrators have full access to all RTX resources, and can also debug RTSS applications.
RTXUsers have read access to all RTX resources. They cannot start the RTX Subsystem, but they can perform the following operations:
Execute RTSS applications (if the Subsystem was started by a Windows Administrator, or a member of one of the other RTX groups)
Terminate RTSS processes
Debug RTSS applications
Register and unregister RTDLLs
Register boot-time applications
Examine product configuration state
Enumerate and examine subsystem objects via the Object Viewer

NOTE: Elevated Administrator accounts will always have the same rights as members of the RTXAdministrators group.

NOTE: Members of the RTXUsers group can run RTSS applications via RtssRun, which starts the RTX Subsystem. However, these members will not be able to see the run status of the subsystem in the RTX Properties control panel, due to the group's access restrictions.

NOTE: When you make a change to any of the RTX groups above, you must log out/in for the change to take effect.

Note that when RTX is first installed, each of these groups includes all users for ease of use:

The Windows group Authenticated Users
The Windows user SYSTEM (also known as LocalSystem).

IMPORTANT! The Windows user SYSTEM must never be removed from any of the RTX groups.

When modifying RTX groups, remove Authenticated Users from the RTX group first, then add individual users based on their usage needs.
