Asus laptop windows 8 update failures.

Hi there.

I just recently bought asus notebook x550C i3 processor,had been working fine for a week. Then lost connection to Internet went to update and restart as updates were needing to be done. After appearing to complete the updates, it then said failure configuring updates, reverting changes do not turn off. It has now been on this screen for 3 hours. I have tried shutting down but when re opens it lands back on same page, with the loop going round and round. I have tried f9, as another forum said that should get me to menu to restore factory settings but that does not work, neither does windows key and r!

i am tempted just to take it back to tesco where I bought it and get new one unless someone can come up with a suggestion in next 12 hours?

appreciate your help.

Depending on how many updates to begin with reverting changes on failure can take a long time. Let it do its thing, it will accomplish and finish.
