My old laptop is a Lenovo ideapad 100 (with windows 10) but just lately when I shut it down a message says Preparing to configure windows. Please don't turn off computer. The problem is it's just stuck at this configuring stage. I leave it for ages and in the end I have to turn the laptop off. When I turn it back on the next day a message says configuring windows update. 35% complete. It's been 35% complete for a few weeks now. Is there anything I can do to help it complete configuring? Thanks.
