    Thanks for this, Mike. I mostly create new 2012R2 VMs from a sysprepped export. But this will work well for the occasional physical installs.

    We've just done a completely new installation of Windows Server 2012 R2 (version 6.3 build 9600). I just ran Windows Update for the first time and it downloaded a slew of initial updates, then rebooted. I had Windows Update check for updates again and it installed 2 additional updates without a reboot, listed below:

    Security Update for Windows Server 2012 R2 (KB2961908) without KB2919355
    Security Update for Windows Server 2012 R2 (KB2920189)

    I had Windows Update check once more, and now it's giving me another 2 updates, one of which is the critical one you describe:

    Security Update for Windows Server 2012 R2 (KB3172729)
    Windows Server 2012 R2 Update (KB2919355)

    A piece of software we need to use recommended having KB2919442 and KB2919355 before installing it.
    However, I checked all the updates which were installed and KB2919442 is not listed. From what I've read KB2919442 should be installed before KB2919355. Should I attempt to install it first using your method described above, or just go ahead and let Windows Update install those two updates?

    Hello All,

    Excuse me but I need your help regarding this update. I trying to install it on a Windows 2012 Server Datacenter Edition (build 9200) . When I double click on clearcompressionflag.exe file I receive 'This App can-t run on your PC'. I tried to re-download the file, change the compatibilty mode, unblock the file, run as administrator, turn off DEP, Firewall, disable Ms Defender and none of these solve this situation. Also cannot install none of other updates showed in the post. The OS is running on a VM and other updates were installed from Windows update service.

    I really appreciate your help or some idea in order to install these updates.

    Thank you very much for your attention.

    Thanks for this, seriously. I don't know why it always has to be a constant struggle with Microsoft and updating. Seriously, I feel like a disproportionate part of my job involves untangling their web of always changing ways/methods/workarounds to update their OSes.

    Does anyone have experience removing IIS or experience with this problem?

    I started to install IIS on server 2012R2. The install stopped other services and I attempted to remove IIS. It will not remove. Apparently, if KB2919355 was installed, a different KB must be installed before IIS can be removed.

    This KB is at https://support.microsoft.com/en-us/help/2957390/you-cannot-uninstall-iis-after-you-install-kb2919355-in-windows-8-1-or

    However, it will not install and responds that this update is not applicable to your computer.

    Several pre-requistes are installed.
