Start in safe mode, and then log in as Administrator or as Administrative User. The Security tab is available for files or folders on NTFS volumes.
Notes: The Everyone group does not include the Anonymous Logon permission.
You can set permissions only on drives that are formatted to use NTFS.
To change permissions, you must be the owner or have the owner's permissions to change permissions.
Groups or users that are granted Full Control permissions for a folder may delete files and subfolders in that folder, regardless of the permissions that protect the files and subfolders.
If the check boxes in the Permissions for user or group box are unavailable, or if the Remove button is unavailable, the file or folder has inherited permissions from the parent folder. For more information about how inheritance affects files and folders, see Windows Help.
By default, when you add a new user or group, the user or group has permissions for Read and Execute, List Folder Contents, and Read.
