[quote=toshiyaDEG]yeah i also have that CCleaner but the last time i used that my registry edit crashed.. after that the task manager and folder options were deleted and after that my pc begins to respond slowly..[/quote] It sounds like you or ur computer tried to run windows updates or install a program directly related to microsoft like MSN Messenger.
