Rizone Take Ownership Shell Extension

Do you find, when you modify system files in Windows 7 or Vista that you have to change permissions a lot? Then this tool is for you. This little utility will add a Take Ownership
Context Menu
Item to all files and folders. This menu option can be
used to modify discretionary access control lists (DACLs). Or, in terms
a normal person will understand, it will grant you permission to modify
a file or folder.
