Windows 10's Creators Update will have its fair share of pleasant surprises, apparently. Microsoft has released a new Windows Insider preview that stuffs in quite a few new features, some of which you might just use every day. For one, its Edge browser now includes tab previews. This isn't a novel concept (hi, Opera), but it'll be immensely helpful if you have loads of tabs open and don't want to play a guessing game. Also, Microsoft's Flash crackdown is in full effect: Edge now blocks untrusted Flash content as a matter of course, and you'll have to click to play it.
