    1. Looks like that decision was changed:

      June 2016 Rollup 2012 R2:

      July 2016 Rollup 2012 R2:

    2. JM says:

      Is there an RSS feed, or other definitive source/list, for Windows Server 2012 R2 Update Rollups?
      It looks like there was a July rollup?

  2. WayneD says:

    I think you will find that the April 2014 rollup for Windows 8.1 (referred in some circles as 'Update 1') was a cumulative rollup which included all previous operating system fixes (Quoting KB2919355: "This update is a cumulative update that includes the
    security updates and the non-security updates for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 that were released before March, 2014".

  3. PL says:

    Thanks for confirming Wayne – this one threw us as well….MS would be nice if you would name any cumulative ones differently in future – here's a thought – maybe call it a service pack 🙂

  4. Ben says:

    The November 2014 Update Rollup includes everything since April 2014, so that counts as a cumulative update as well.

  5. thomas says:

    There are some issues with the latest media that includes the November 2014 update rollup. Please find details here:

  6. adam says:

    Thanks for this, are you going to update if applicable.

  7. UR_h8er says:

    Does anybody know why no Update Rollups released since December 2014?

  8. Anonymous says:

    Wondered the same thing so we asked our Microsoft TAM. We were told that Microsoft has been focused on security updates in the first quarter rather than rollups, but they would be releasing some when they were available. No word on when that would happen

  9. No more rollup? says:

    What happened to the monthly update rollup? Nothing since January and no communication from Microsoft about it.

  10. Darren Milne says:

    Isnt KB3027209 a March 2015 Rollup ?

  11. Marcel Buehring says:

    @Darren: NO!

  12. So to sum it all up (and please correct me if I'm wrong):

    – December 2014 is the last rollup pack and will probably be the last one since MSFT's focus is now on W2016.

    It took me a while to slipstream these patches the correct way using DISM, because even after that WSUS was still trying to install them. Turns out I had the order wrong so, for everyone who's having the same problems as me and has absolutely no clue at all
    which rollups to install (because I guess it makes sense when you install a rollup you still need the previous rollup) use this order:

    – First install KB2919442 (This is a mandatory update required by kb2919355)
    – Next install KB2919355
    – Then install KB3000850
    – Finally, add KB3013769

    Then you have all updates mentioned in this article and you are on December 2014. If you slipstream patches with DISM like me, install the server with these patches slipstreamed in that order. Next run Windows Update on that server and install all patches available
    until now. Use that as reference image to slipstream all patches from December 2014 until now.

    Cheers! 🙂

    1. Hi Martijn! Can you clarify me? So, if I download, for example, with the media creation tool the ISO of Windows 8.1 from Microsoft servers, I only need: first install KB2919442 (this is a mandatory update required by KB2919355), next install KB2919355, then install KB3000850 and finally add KB3013769 like you said? And I only need the rollup updates from December 2014 until now? Thanks for your time 🙂

    Great list! Thanks for doing this, it really helps and I point customer to this regularly. Can you please update the list to include the 2012 R2 June 2016 Rollup Update which supersedes the May 2016 RUpdate. Here’s the link:

    June 2016 update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2


  16. Kobberoe says:

    And never say never again, the May 2016 update rollup has been superseded by a July 2016 update rollup,

  17. RJR says:

    Please add the latest Rollup Updates to these lists.


  18. Hi there! I saw the Rollup Updates above but the scenario of my doubt is this: I used the media creation tool to download ISO of Windows 8.1 x64 and the size is 3.28 GB (3.449.728 KB). But downloading the ISO from TechBench the size of it is 4.02 GB (4.219.264 KB). What is difference between them?

    After understanding the question above, what is the correct order to apply all the available rollup updates?
    If the downloaded ISO (with media creation tool) contains already any updates, which rollups I really need?
    I only need the 2016 updates or any previous one(s)?

    I would appreciate a step-by-step procedure on installation of all updates. This situation is very important to me.

    Thanks for your attention.
    Best regards
