Help me with the information for a restore,
As restore will take the device to a previous location when computer was working fine, only if there are avaialbe restore points.
IF you need to remove all the application only :
Try a reset from settings.
Else I will suggest to back up everything and try a recovery. ( in case less applications installed)
However this is a big step as there could be issues on windows updates installing.
So please update before performing one.

restore : http://support.hp.com/us-en/document/c03327545
Please do create the recovery media, if not created.
