I repairing with the OS cd in the repair mode followed the guiding from MS official page for repairing Windows. After that i could not use any application from the all programs menu. But i can access those applications from the Program files folder. All file types are requiring open with programs. And my Add/Remove menu is empty. I couldn't uninstall those programs.
