About this tag
The built-in users group in Windows is a security principal used in NTFS permissions and access control lists (ACLs). Discussions on WindowsForum.com cover how built-in users appear in ACLs for system and data partitions, such as the difference between C: and D: drive permissions. The built-in users group is referenced in icacls output alongside other well-known security identifiers like BUILTIN\Administrators and NT AUTHORITY\SYSTEM. Understanding built-in users is important for managing file system security, user profiles, and partition permissions in Windows environments.
Hi
In Windows7 SP1, I noticed that the ACLs of the root directory of a logical partition (D:) formatted NTFS are different from those of the root directory of the system partition (C:):
C:\Windows\system32>icacls c:\
c:\ BUILTIN\Administrators:(F)
BUILTIN\Administrators:(OI)(CI)(IO)(F)...
