Windows 10 build 10240 has released to the Fast Ring… Release To Manufacturing (RTM) build???

build 10240 has been released to the Fast Ring. That's what I'm on my laptop now. There were heavy rumors yesterday that this is the to Release To Manufacturing (RTM) build and is the one to be publically available on July 29th. But there is no hard confirmation on this by yet Build 10240 now available for Windows Insiders in Fast and Slow rings.

“Over the past few days we've been preparing our release pipelines and processes, and this build is one step closer to what customers will start to receive on 7/29 …

On Monday we announced that builds from here on will only be available through , so to get this one you can either wait and it will be installed automatically.”

Here's how you prepare to roll it out in your company.

In a previous blog post I wrote about the update you needed for your to be able to activate Windows 10 clients. Read about that in KB3058168: Update that enables Windows 8.1 and Windows 8 KMS hosts to activate a later version of Windows

Meanwhile Microsoft has also published the Windows 10 client KMS activation which keys can be found here Appendix A: KMS Client Setup Keys
