Windows 10: What We Know About the Launch

— -- Microsoft has moved the release date for Windows 10 even earlier, revealing the operating system update will reach consumers sometime this summer.

Windows 10 will be available in 190 countries and 11 languages, Terry Myerson, Microsoft's executive vice president of operating systems, said at a Windows summit in Shenzhen, China, on Tuesday night.

While an exact release date hasn't been announced, Microsoft had previously been targeting a late-2015 release date for the software.

Myerson also showed off more of what to expect, including Windows Hello, a system that allows users with biometric sensors to log onto their Windows 10 computers using their face, iris or fingerprint.

Other changes include the addition of Cortana, Microsoft's virtual assistant, and a more integrated experience across all Microsoft devices.

Internet Explorer will also take a backseat in Windows 10 to make way for Microsoft's new browser, code-named Project Spartan, which is expected to be a faster and sleeker way to browse the Internet.
