User Groups and Access Permissions

wRTOS provides the Windows user groups listed below, in addition to the native Windows Administrator group. These groups allow for granular control of wRTOS permissions.

Group	Permissions
wRTOSAdministrators	Full access to all wRTOS resources, including the ability to debug RTSS applications
wRTOSUsers	Read access to all wRTOS resources Execute RTSS applications Debug RTSS applications Terminate RTSS processes See Notes below.
Windows Administrator	Boot configuration Configure Windows Idle State Convert devices

By default, all authenticated users who log on to the system can control, configure, and run the wRTOS Subsystem and RTSS applications. The default wRTOS groups include:

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

System administrators can control access to the wRTOS resources by configuring members of the wRTOSAdministrators and wRTOSUsers groups.

IMPORTANT: The Windows user SYSTEM must never be removed from a wRTOS group.

When modifying wRTOS groups, remove Authenticated Users from all wRTOS groups, then add individual users to specific groups based on their usage needs.

Notes

• For a member of wRTOSUsers to perform the actions listed in the table above, one of the following scenarios is required:
• Someone with greater permissions must first start the Subsystem for them.
• The wRTOSUsers member must elevate, via Administrator Command Prompt, the application they wish to run or terminate.
• Members of wRTOSUsers cannot stop wRTOS Network components (NL2, Network Relay, E-CAT, TCP/IP).
• Only one instance of wRTOS Settings can be opened in a session. For example, if a member of wRTOSAdministrators has opened wRTOS Settings, a member of wRTOSUsers cannot open another instance.
• When you change any of the wRTOS groups above, you must log out and then log back in for the change to take effect.
• If you encounter an error while attempting an operation, check your wRTOS group membership.
