Windows 10 Mobile cumulative update

Microsoft is today rolling out new cumulative updates for Windows 10 operating system. The company has also released new updates for all supported versions of Windows 10 Mobile, and while the company has detailed the improvements for desktop, the changelog is not available for phones. This is not surprising as Windows 10 Mobile is in maintenance mode which means that Microsoft is not focusing on new features or hardware.

To line up with today’s Patch Tuesday updates for Windows 10 desktop, Microsoft released build 15254.401 for Windows 10 Mobile handsets running the version 1709. The phones such as Lumia 950 and HP Elite x3 are part of the rollout.

Microsoft today pushed out Windows 10 Mobile 15254.401 to the general public across the globe. As you might have guessed already, the new build 15254.401 for Windows Phones brings the usual list of security improvements. We assume that the new build for Windows 10 Mobile also includes general bug fixes and improvements.

Needless to say, Microsoft is still working on security fixes for the Windows 10 Mobile version of the Windows 10 Fall Creators Update. It’s also fitting to see that new security updates are getting released for Windows 10 Mobile at least once a month.

The last few years have been rather uneventful for Windows 10 Mobile as Microsoft has stopped developing new updates with features and major improvements. The situation won’t change as Microsoft’s Joe Belfiore has already confirmed that the future Windows 10 Mobile updates will mostly have bug fixes and security improvements.

Last year, Microsoft’s Joe Belfiore, Corporate Vice President in the Operating Systems Group officially announced that Windows 10 Mobile has been discontinued and the company won’t release any feature updates for the platform. He also recommended customers to switch to Android and iOS.

Last week we discovered that Microsoft has quietly updated the support article to announce Windows 10 Mobile April 2018 Update. While the news excited many fans, but as speculated by us, the support article is merely a mistake on Microsoft’s part. The Microsoft support site actually tells users how to update to the Windows 10 April 2018 Update, even though it doesn’t exist.

You can manually check for the update by navigating to Settings > Update & security > Phone update > Check for updates.

    The Microsoft support groupe a newbies!

    • That sucks your Windows phone stopped working. Mine I still going strong.

      • pege63

        No my WPs still working and going and doing it strong, I just made a comment.

      I agree it is heartbreaking, but I’ll use the 950 for as long as I can. I guess the Icon will become an icon sort to speak.

      Oh well, it gives me time to program a legacy device. Hell Linux is still around, right?

    • M Rankin

    You know there is an error code no. 0x80070273 that prevents many phones from being able to install updates. Why would you not fix it in this update???????? Got to jump thru a bunch of hoops again. Thanks M$. PS: where’s the new folding phone, we’re still waiting. You really want us all to go to A or A. By the way, I may be looking in the wrong place but, I’m not seeing a lot of new cars coming out with Windows in the console anymore. Aren’t you leaving a lot of money on the table there.

    updating my Alcatel Idol 4S… sweet!

    You don’t want the work. Go ahead, fire some more people. Apple, Android and Amazon will gladly take all the business you don’t want to do. You’re just flat plain lazy leadership wise.

    I checked for an update on the phone and found “2018-05 Update for Windows 10 Version 1709 for arm-based Phone Device”. Have a 950XL. Downloaded and “Preparing to install”

  • Chris H

    Does anyone else use the “Project My Phone” app? This was the main thing I still use on my 950XL. I updated to the 15254.401 build and simultaneously on my desktop updated to version 1803 and now Project My Screen does connect to the phone ok and can operate the phone, but just shows a black screen. Does anyone know a fix for this or also seen it happen?

    Im using 950xl too, fast ring. i did not receive this update
