Microsoft made a bit of a boo-boo yesterday when it accidentally published an empty blog post revealing the launch of its Windows 10 Anniversary Update on August 2. Today it officially confirmed that date and reiterated some of the new features that will be available to users.

Windows Ink is perhaps one of the flagship features of the update, allowing you to do more with a pen inside Windows 10. New features include the option to quickly write notes, sketch on screenshots, create Smart Sticky Notes that look a bit like Post-Its and new features that take advantage of handwriting inside of applications like Office.

Cortana is getting an update, too, and will now be available on the lock screen. She can also save “key information, like your frequent flier number,” and can shoot notifications across all of your devices, so you never miss an alert.

The Windows 10 Anniversary Update also adds new security features, Windows Hello sign-on support inside the Microsoft Edge browser and more.

You’ll need to be on Windows 10 in order to take advantage of the update, of course, and you have exactly one month to update your computers to the new operating system for free.
