Registry Editor: A main registry editing tool equipped in all versions and editions of Windows operating system, can be disabled, blocked and locked to prevent the RegEdit from been ran or executed by users in order to protect important system registry. Other possibility of Registry Editor been disabled is caused by virus or worm such as W32/Brontok-C.
When Registry Editor is disabled, user unable and cannot open or run Registry Editor anymore. Any attempt to run RegEdit.exe will return the error “Registry editing has been disabled by your administrator”.
