Windows 10 reaches RTM status, available now to Insiders

Works is not done by a long shot. Patches will come on rollout day in two weeks.

Microsoft Windows 10 RTM

Multiple sources, including The Verge, Paul Thurrott, and ZDNet's Mary Jo Foley, say that Microsoft has finalized work on Windows 10, for now, and has sent Build 10240 to OEMs as its official release to manufacturing (RTM) code.

RTM is a bit of a misnomer these days, since RTM was for stamping CD or DVD versions in prior releases of the OS. Most people will get Windows 10 now via a download. Still, it indicates Microsoft is done, for now, with its OS.

Or not. Thurrott said one insider told him Microsoft has not signed off on Build 10240 as the RTM build, but at the same time, it is no longer creating new builds, either. Just making patches for the 10240 build. Either way, Microsoft seems to have settled on 10240.

Word is that Build 10240 will be made available to the five million Insiders who have been integral to testing the OS over the past year. It will also be sent to hardware OEMs to begin installing it on their hardware.

Microsoft has issued another blog post on the final code, with Gabe Aul noting on the Windows Blog that the watermark from previous versions has been removed. 

"This build is one step closer to what customers will start to receive on July 29. Builds from here on will only be available through Windows Update…" he wrote.

"Remember that you’ll need to be logged in with your Microsoft Account in order to receive the build. Besides builds, over the next 2 weeks you’ll also see some Windows Updates and app updates in the Store, so make sure to keep checking for updates daily to make sure you’re running the latest and greatest code," Aul added.

Interesting trivia note: Windows 95 was released to manufacturing on July 14, 1995. So 20 years and one day later comes its descendent.
