Need a icons to do the above in Windows OS?
Easy! Just create a .bat file and fill in the following:
For Shutdown:
1 | shutdown.exe -s -t 00 |
For Reboot:
1 | shutdown.exe -r -t 00 |
For Logoff:
1 | shutdown.exe -l |
For Abort Shutdown:
1 | shutdown -a |
Take note that the -t parameter is the number of seconds Windows take to perform this task. For instance if shutdown.exe -s -t 3600, Windows will takes 1 min before it shut down.
Hope it helps
