Failure configuring Windows updates, reverting changes

I just bought new Asus Vivotab Smart Windows 8 tablet, after the very first windows update it failed to install some of the updates, and then after the reboot I am now stuck with the message "Failure configuring Windows updates, reverting changes".
It never gets any further than this, it never reverts, I have left it running for an entire day and have restarted several times.

please note that this is a tablet, so there is no keyboard so I cannot press any F keys to get into recovery mode, and no CD to boot from etc.

Hi Snake,
had to leave my lappy COMPLETELY alone for it to finally revert.
After that go
ControlPanel>WindowsUpdate>reviewhistory>troubleshoot.
Then install updates.

hawkman,

it has been left for an entire day already, so I really think it is broken.
