Hi,I downloaded windows 10 approximately 10 days ago, all worked great till Thursday then a box popped up to say there's a problem with this PC, we are fixing it, it's fixed, we will do a restart. It did a restart and then carried on working ok. When I tried to shut down it said pleas leave on as McAfee is installing updates. Then to my horror 1by1 all my shortcuts disappeared and I can't get anything to work?
