I've used Windows10 since it was released and like it, but I think it still has a few issues that need sorting out. The start panel suddenly refused to open about 3 weeks ago after an update, so I did a restore which brought it back for a few days, then it went again. Also Chrome wouldn't open. I searched online and found it was quite common, so tried several of the solutions, none of which worked. Other solutions looked too complicated, so I didn't dare try them. Then I found a forum where someone mentioned that they'd removed Dropbox and that fixed it, others backed him up. I tried that and it worked! Apparently there is conflict between some programmes, especially when they update, and Windows10.
