• Supports the following object types on Windows 2000 and later
  • NTFS files and directories
  • registry keys
  • printers
  • services
  • network shares
  • WMI objects
• Manage permissions on local or remote systems in domains or workgroups.
• Set multiple permissions for multiple users or groups in a single command.
• Control how permissions are inherited.
• List, backup and restore permissions.
• All operations work on a single object or recursively on a directory or registry tree.
• Set the owner to any user or group.
• Unicode support.
• Remove, replace or copy a user or group from an ACL.
• Fast performance. This is due to time consuming steps only being performed only once. An example of a time consuming step is the recursing of a large file system.
• Filter out object names not to be processed.

Usage

To set 'change' permissions on the directory 'C:\angela' for user 'brian' in domain 'dom1':

SetACL.exe -on "C:\angela" -ot file -actn ace
           -ace "n:dom1\brian;p:change"

Remove write and change permission sets from Desktop, replace with 'read and execute' permissions:

SetACL.exe -on "\\mycomputer\C$\Documents and Settings\username\Desktop" -ot file 
           -actn ace -ace "n:mycomputer\username;p:write,change;m:revoke"
           -ace "n:mycomputer\username;p:read_ex"

An example of its use from AutoIt can be found here
