My laptop runs Windows 8 and when it went to update to Windows 8.1 it failed. Now, every two days it tries to update to it again, but every time it does so, it fails again. To do this update it has to restart my laptop, and as a result of it failing it has to revert all the changes, so I'm left without use of my laptop for a few hours. Seeing as it always fails this update, I've come to the conclusion that it will never actually be able to do it, but I can't find anywhere for me to tell it not to do the update.
