How do you restart the windows 7 operating system?

Answer 1

Hold down the Windows key on your keyboard and tap the R key. This opens the Run box. Type in "cmd" and hit Enter. This opens the Command Line window. Type in "shutdown -r -t 00". Your computer will restart immediately. Leave off the "-t 00" if you want it to wait 30 seconds before restarting. Use "shutdown -s" to shutdown fully instead of just restart. Or you can use the "shutdown -l" option to logoff.

Answer 2

by clicking the option restart in control panel
