MY REGISTRY EDITING HAS BEEN DISABLED. WHEN I TRY TO OPEN REGEDIT, IT GIVES MESSAGE THAT REGISTRY EDITING HAS BEEN DISABLED BY YOUR ADMINISTRATOR. I'M MYSELF ADMINISTRATOR OF THIS PC AND EVEN IF I RUN IT AS ADMINISTRATOR, THE MESSAGE IS SAME. MY OS VERSION IS WINDOWS 7 ULTIMATE-64 BIT. COULD ANY ESTEEMED FORUM MEMBER HELP ME OUT IN RESOLVING THIS ISSUE. SIMILARLY, MY TASK MANAGER HAS ALSO GOT CORRUPTED AND I'M NOT GETTING MENU ITEMS ON TITLE BAR OF THE TASK MANAGER. THIS OBVIOUSLY LEADS ME TO A SITUATION WHERE I'M NOT ABLE TO CLOSE ANY NON-RESPONDING PROGRAM. IT IS PRESENTLY SHOWING ONLY THE SERVICES RUNNING. REGARDS
