Shutdown Timer with out any software

I found out how to shutdown the computer using a batch file.. and how to set a specified time to shut off...


try the following code...that having some menu selection 

"paste those code in note pad and save as a bat file."

@ECHO OFF

CLS

:Start
ECHO When do you want to shutdown?
ECHO Press number of choice followed by the Enter key
ECHO 1: Fifteen Minutes
ECHO 2: Thirty Minutes
ECHO 3: Sixty Minutes
ECHO 4: Quit

SET Choice=
SET /P Choice=""

IF '%Choice%'=='1' GOTO Fifteen
IF '%Choice%'=='2' GOTO Thirty
IF '%Choice%'=='3' GOTO Sixty
IF '%Choice%'=='4' GOTO End
CLS
ECHO "%Choice%" is not valid
ECHO Try again
GOTO Start

:Fifteen
SHUTDOWN -S -F -T 900
GOTO End

:Thirty
SHUTDOWN -S -F -T 1800
GOTO End

:Sixty
SHUTDOWN -S -F -T 3600
