Microsoft has released a new version of Windows 10, build 10240, that will be available for Windows Insider members on both the Fast and Slow update rings. This is the build that is rumored to be the RTM (Release to Manufacturing) version that will be sent to PC OEMs.
Windows Insider head Gabriel Aul wrote:
"On Monday we announced that builds from here on will only be available through Windows Update, so to get this one you can either wait and it will be installed automatically (but who are we kidding, I know you want it now!) or go to Start > Settings > Update & Security > Windows Update > Check for updates. 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 " .
One thing that is noticeable with this build is that the desktop watermark with the build number has been removed. Aul also posted a teaser about a "least one fun surprise for Windows Insiders coming up" which means there may be more updates coming before Windows 10 officially launches on July 29.
