Press Release

July 9, 2012 — Today in Toronto, Canada, at Microsoft’s annual Worldwide Partner Conference, Windows Chief Marketing Officer and Chief Financial Officer Tami Reller spoke to thousands of partners from around the world. She shared some exciting new details regarding Windows that I wanted to pass along.

For the first time, we provided details on Windows 8 availability. Tami confirmed that Windows 8 is on track to Release to Manufacturing (RTM) the first week of August. For enterprise customers with Software Assurance benefits, they will have full access to Windows 8 bits as early as August. Additionally, she noted that RTM is when we’ll be turning on the commerce platform so that developers can start earning money for their apps – we’ll have more to share on the Windows Store for developers blog soon. Of course, right now with the Windows 8 Release Preview, all apps are still free for people to try.

Tami went on to say that Windows 8 will reach general availability by the end of October! This means that new Windows 8 and Windows RT PCs will be available to buy and upgrades will be available starting in October. She also mentioned that that Windows 8 will be available in 109 languages across 231 markets worldwide.
