Least Privilege not showing full list of Windows Services

Key Differences in SDDL
PRTGCoreService does not have permissions for AU or AC, which might be why it cannot be queried via WMI.

ClipSVC has permissions for AU (LCRP), meaning Authenticated Users can query the service state.

Trying to fix the above gives is an error:

sc sdset PRTGCoreService D:(A;;CCLCRPLORC;;;AU) 

or

sc.exe sdset PRTGCoreService D:(A;;CCDCLCSWRPWPDTLOCRRC;;;SY)(A;;CCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;IU)(A;;LCRP;;;AU)(A;;CCLCSWLOCRRC;;;SU)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)
