Solve a few faults that can't open the task manager

Q: I can't open the task manager after pressing "Ctrl+Alt+Del" in Windows XP; click the right mouse button on the taskbar to see the "Tasks" Manager & rdquo; is gray. May I ask how is this going? How to recover? A: This situation should be caused by restrictions in the registration. Please type “gpedit.msc” in the Run box to open the Group Policy Editor, and then expand “User Settings →Administrative Templates →System →Ctrl+Alt+Del Options”, double click on the right side of the “ Delete the Task Manager & rdquo; item and change its setting to “not enabled”.
