Dave, so far it seem like you have to train it in some areas, some programs it won't allow unless you approve it, which you can approve it for one time or allow it to open at any time. I'm running Windows 8.1 on this laptop, I'm assuming it will work the same on W-10. I haven't tried it on my Linux machine which has firefox, going to try it though later. So far I like it, seems to be faster than IE. PJ
