An elderly friends wife died not long ago and she had an Iconia Tab 8 W1-810 that she used.  He was looking to sell it or pass it on to someone so he asked me to help as its locked with his wife's account.
 
I cant reset her Live password, no one knows the details to be able to answer the security questions she set up.  I thought it would be a simple matter of certain key presses to bypass or wipe the machine, but the best I can get to is the setup utility by holding the volume and start buttons for a certain time.  Even that is hit or miss.  Holding shift while pressing restart does absolutely nothing.  Unlike the Android version there's no 'wipe' selection to do a factory reset on it, and because its locked with her password I can't simply go into any settings on the tablet and wipe the account.
 
How do I do a factory reset on this tablet?  Is it possible to get past that account password somehow?  Any ideas greatly appreciated.
