Change File and Folder Permissions with NTFS Permissions Tool
It has a nice UI.
Set File and Folder Permissions for System Files with NTFS Permissions Tool
With the release of Windows Vista, Microsoft has made the system files read only for normal users in Windows. You cannot delete or modify system files unless you take ownership of the files. This feature was carried forward to Windows 7 as well. Although Windows allows you to modify the permission, it is not a direct process. NTFS Permissions Tool is a simple freeware tool which allows you to set permission on any file or folder in Windows and also change the ownership of files."
Came across this tool here.
Thanks for this japp. Will see how it works.
