Windows 10 Cumulative Update KB3124263

There aren’t any major new features in this update, but it does include minor OS improvements and bug fixes.

At the time of this writing, Microsoft hasn’t included any notes for the update yet on its Support page, but we’ll update this story when they come in.

Microsoft has updated its KB Support page and includes the following:

This security update for Windows 10 Version 1511 includes improvements in the functionality of Windows 10 Version 1511 and resolves the following vulnerabilities in Windows:

  • 3124605 MS16-008: Security update for Windows kernel to address elevation of privilege: January 12, 2016
  • 3124901 MS16-007: Security Update for Windows to address remote code execution: January 12, 2016
  • 3124584 MS16-005: Security Update for Windows kernel-mode drivers to address remote code execution: January 12, 2016
  • 3124275 MS16-001: Security update for Internet Explorer: January 12, 2016
  • 3118753 Microsoft security advisory: Updates for ActiveX kill bits: January 12, 2016

Windows 10 updates are cumulative. Therefore, this package contains all previously released fixes. If you have installed previous updates, only the new fixes that are contained in this package will be downloaded and installed to your computer.

There is also a known issue for Windows 10 users running Citrix XenDesktop not offering the update. Microsoft advises: “Customers should contact Citrix for more information and help with this XenDesktop software issue.”

You’ll get this latest update automatically at some point, but if you don’t want to wait, you can grab it manually by going to Settings > Update & Security > Windows Update.

You also will need to reboot your PC to complete the update process. But you can always schedule the restart for a time that works best for you. For more on that, read our guide on how to schedule Windows 10 Update restarts.

Restart Required

After the update and restart is finished, launch Run from the hidden quick access menu or hit Windows key+R and type: winver and hit Enter. There you can see that your Windows 10 build number has jumped up a bit.

Build 10586-63

      Do this type windows + R , then write “services.msc” it will open a window search for windows update and do right click and select restart. Wait a moment and go to configuration , update and security , and press in search for updates and it will download again the failure updates that you will have

      @My Own comment: Solved the problem by restoring to a restore point created one week ago.

      Interestingly I had to do this for both my laptop and pc desktop as both reported a “corrupt update service” today, which was not present prior to attempting to install all updates offered.

      I assume that somewhere along the line (in between my restore points set a week ago) Microsoft got something terribly wrong. Nonetheless all went well after that. If the restore point wasn’t going to work I was ready to restore from a system image – luckily I didn’t have to resort to that.

      Thanks Microsilly!

    If you did not have Ver 1511 would getting this update include that too ?

    Thanks for the eyes-up, – head down warning – I’ve just done a restart for an earlier set of changes (Tuesdays?), that, in the partially installed state seemed to stop Outlook 2010 sending mail.
    And I’ve recently completed (I hope) redoing the specialisation I had on my system setup – Task Manager, and other facilities as well as Office settings.

    I’ll delay the restart for this set for a couple of days!

    I’ve now resolved my update-problems, by using the media creation tool´, to download and reinstall windows 10 (upgrade), and choosing to download all the updates, and I’m now on windows 10 1511 build 10586.63!

    Following on from my setting the restart for the update to be delayed –
    leaving the OFFICE 2010 fix KB3114557 to be ‘completed’
    I now seem to have a modified Shutdown – the options are effectively sleep,
    SLEEP – which means keep the system powered

    no HIBERNATE, and no just SHUTDOWN

    Every time I update windows something gets broken. After the last security update of windows 10, the wifi adapter stopped working.
    Have you faced any issue after the update?

    It done crazy stuff with my graphics drivers, they keep stop working causing the screen to freeze and then a message saying they have rolled back. It didnt happen before the update.

    I literally cannot handle Microsoft updates anymore. My PC freezes without warning. Looks like the latest update batch is at fault. This morning I have lost 5 hours and still counting. I really don’t want to uninstall / reinstall.

    As soon as I can I am dumping it and moving over to Apple.
