In an INF file under Privilege Rights there are five options and I want to know what to mean.

I know
*S-1-5-32-544 stands for Administrators Group
and
*S-1-5-32-545 stands for Users group
and
*S-1-5-32-545 & *S-1-5-32-544 stands for both.

What does *S-1-5-32-546 stand for and if there is nothing listed is that full access or is that no access?
