New Windows 10 Technical Preview build's '7,000 new changes' include notifications

That doesn't mean the new build represents a total improvement. In some cases, the UI of the technical preview went "backward" temporarily while Microsoft focused on how things work, not how they look: Internet Explorer glyphs may look garbled, and items on the Start menu might disappear, for example. Some machines may not sleep properly, and Wi-Fi functionality also regressed. That's to be expected with a new build, Aul said.

Still, adding notifications could mean that other rumored features are on their way, too. Here are our first impressions of the first build of Windows 10; feel free to add yours, below.
