Microsoft's much-anticipated updated to Windows 8 will be free, will be called Windows 8.1 and will be out "later this year."
All this news came on Tuesday when Tami Reller, the CMO and CFO of Microsoft's Windows Division, addressed JP Morgan's Technology, Media & Telecom Conference. Reller wouldn't commit to a launch date, but promised a public preview edition when Microsoft's Build 2013 developers conference opens on June 26. Some reports interpreted Reller's remarks to hint at a full release around the Holidays.
Windows 8.1 will work on both Windows 8 and Windows RT, the version of the operating system that runs on ARM processors.
