SUMMARY
=======
If you choose to format the system partition with the Windows NT file system
(NTFS) during Setup, permissions granted according to settings in the
WINPERMS.TXT file. When you choose to convert a partition to NTFS after you have
installed Windows NT, permissions are set so that everyone has full control of
the files on the partition. This behavior is expected, and by design.
MORE INFORMATION
================
If you choose to format the system partition with the Windows NT file system
(NTFS) during Setup, the following Registry entries are added under
HKEY_LOCAL_MACHINE\CurrentControlSet\Control\Session Manager\BootExecute:
autoconv \DosDevices\<systemdrive>: /fs:NTFS
setacl /a \DosDevices\<systemdrive>:\WINNT35\System32\winperms.txt
\DosDevices\<systemdrive>:
The second to last time Windows NT boots, AUTOCONV.EXE runs to converts the
partition to NTFS, and SETACL.EXE runs to set default permissions on the
partition. SETACL.EXE gets permission settings from the WINPERMS.TXT file. Setup
places WINPERMS.TXT in the %SYSTEMROOT%\SYSTEM32 directory.
On the other hand, if you chose to convert to your partition to NTFS after you
have installed Windows NT, the Autoconv registry entry is added, but the setacl
command is not. Therefore, permissions taken from parameters contained in
WINPERMS.TXT are not set on the NTFS partition. Thus, everyone has full control
of the files on the partition.
