Unwanted startup notices

[Guest]

When I restart my computer, a pop up notice comes up that says "do you want
to restart your computer now." How do I disable these notices?

Make a shortcut to shutdown.exe and place it on your desktop. Running
shutdown without any switches will give you its options.

 

[JS]

Restart command:
shutdown -r -t 01

Note: You will need a space between the -t and 01 (values from 00 to 99
seconds are allowed)

Shutdown command:
shutdown -s -t 15

For a list of the commands available open a command window and at the prompt
just enter shutdown (without any switches)
