Shutting Down Your Computer

Ending a Process That is not Responding
Use the Task Manager to end (terminate) processes that have stopped
responding. A process can be a program, such as Windows Explorer, or a
service, such as MSTask.
1 Right-click the taskbar, and click Task Manager→ Processes tab.
2 In the Process tab, select the process that is not responding and then click
End Process.
HINT: Be careful when ending a process. If you end a process
associated with an open program, the program will also close and you
will lose any unsaved data. If you end a process associated with a
system service, some part of the system may not function properly.
FOR MORE INFORMATION: To learn more about what to do when a
process does not respond, see Windows Help and Support: click Start
or → Help and Support.
