Make shutdown through Notepad

In notepad just type

shutdown -s (there is a space between shutdown and -s)

save the file as shutdown.bat (or anyname you want but with .bat extension)

To avoid this shutdown Click

Start->run->

and type shutdown -a (just copy and paste)

If you want to increase time before shutdown

write command in this format

shutdown -s -t 100000 (or upto whatever digit you want but remember to put spaces in between i.e shutdown space -s space -t space 100000 )
