Today Microsoft unleased build 10240 to both the fast and slow rings for Windows Insiders. The Verge reported earlier today that build 10240 would be the “RTM” or “Release to Manufacturing” build and while that has not officially been announced, this build does take some big steps towards being less of a testing build and more of a release candidate.

One obvious change that signals this is not a typical beta build is that the Windows Version watermark in the bottom right corner of the screen is now gone. Another point to make is that this build has been released to both the fast and slow rings at the same time, so clearly they have tested well internally. Since it is in the slow ring, typically that means that there will be ISOs released but perhaps it is too early for that.

The blog post doesn’t have much else in the way of details which makes sense since they have moved into a bug fixing phase rather than adding features. One thing that they did say is that their new browser, Microsoft Edge, continues to receive performance updates and they show it faster than Chrome in several javascript benchmarks. This is in line with what I tested back in January when the Edge rendering and ECMAScript engines could be enabled inside of Internet Explorer 11. I’m downloading the latest build now so once completed I’ll compare it to the numbers we saw in January to see what kind of increases in performance (if any) have been made in the last six months.

The touch first versions of Office have been available on Windows 10 for a while now, and they have now dropped the preview moniker but gained the Mobile name to distinguish them from the desktop counterparts. On phones, the mobile name is not necessary since you can’t have both installed anyway.

Today marks two weeks until launch, and the RTM build (if this is it) will be shipped to OEMs to use as the basis for them to install on new hardware. For those that are not in the Windows Insider program, up until now every new build has been a full install of Windows overtop of the existing one, and once they move to RTM it will likely shift to a Windows Update style where just components are updated rather than the entire OS, which should make it a lot quicker to get updates.

Check out Windows Update now and be sure to be signed in with your Windows Insider Microsoft Account in order to get the latest build.

    I was playing a game on my Stream 7 and it overheated my CPU to the point where it throttled down to 40 MHz. After it got back up to 100 MHz, Windows itself ran fine. I was kind of surprised Windows needs so little computing power! The graphics power is a different story.

    I am running on an old laptop (Core2Duo 2GHz/ 4GB/SSD) and my biggest problem originally was Windows Security/Defender. Once replaced by BitDefender (even tried Avast at a time a bug showed up), CPU usage was much lower. Otherwise, my CPU would *NEVER* idle.
    Updating to the latest now.

    You sir are a "master of the obvious"

    My biggest problem is that it STILL insists on converting my local account to a microsoft account, which I do not want to do, and that is the only way to upgrade to the 10240 build. And they stated that they want to test the windows update process, so no ISOs for the time being. I'm fine with that, but then why constrain the process by forcing to convert to microsoft account? That makes no sense to me, since every other app is usable with specifically logging into the app with a microsoft account. Everything BUT the upgrade...

    The Windows Insider program requires a MSA, but once it ships out you don't need a MSA for anything except the Insider program, or apps that require it like OneDrive. In fact its much easier to not use a MSA in Windows 10 than 8.1.

    I do have an MS account, since being an insider requires that, and I'm totally fine with that. What bothers me is that it wants to convert my local account into an MS one for the upgrade. Up to build 10130 this was not needed. It just asked for the MSA login without converting the whole local account. (And the feedback app still works perfectly fine this way)

    You can disable microsoft account and use local account instead.
  • zoxo - Thursday, July 16, 2015 - link

    yes, you can, but you can't upgrade to 10240 without converting to MSA

    then just switch your online Microsoft account to a local account again right after you upgrade. ..You don't have to stay online with a Microsoft account.

    I don't understand why you would want to use Windows without a Microsoft account? Please enlighten me?
