    Is the abort command supposed to work if one has issued the reboot from GUI. I have tried this on my Windows 7 Ultimate, it does not seem to be working. it says ‘no shutdown was in progress’

      Abort works only when you had issued the reboot/shutdown using the command. GUI actions are not aborted by /a option.

    I’ve just attempted all commands from Windows 7 Ultimate install disk (used as recovery disk) and I obviously have a fault with my disk trying to load the Windows installation volume, I’ve launched command prompt via shift F10 as the GUI was not responding or should I say it had a never ending hour glass, trying a force shut down resulted in ‘the function is unknown’ proceeded with some numerical digits inside of closed brackets?

    Shutdown /a is very handy when windows update tries to force reboot your computer. You can run this command and cancel the reboot if you don’t want the reboot to happen at that time.
