The 10 Most Righteous New Features Coming to Windows 10

As long as you have a face, Windows Hello wants to make sure you don’t need a password.

Hello is an awesomely fast way to unlock your computer, and should work just as well everywhere. Just, you know, don't get decapitated—then you won't be able to log in with this cool feature.

Microsoft’s Bryan Roper said during the Build keynote that 8 million people use [Windows 10](http://www.wired.com/tag/windows)’s built-in sticky notes app every month, and 3 million use it every day. So Microsoft has made the notes a little smarter. They do a good job of reading your handwriting, and Cortana can recognize dates and turn notes into reminders. It’s particularly useful if you’re writing with a Surface Pen. Speaking of which...

Pen input is really, really important to Microsoft. And the Windows 10 Anniversary update has a lot of pen involved. You can use an on-screen ruler to draw perfectly straight lines, draw a line between two dots in Maps to calculate the distance, highlight and delete text in Word, and much more. Pen’s only one of many input mechanisms in Windows 10, but it’s clearly one of the most important.
