    Have to say thanks for this. The instruction to install everything as well as the later KB2919442 update is priceless.

    In my case, it was to KB2919355 to an 8.1 Hyper-V VM. Eventually did it.

    I did not install in the order specified but I can say that KB2919355 will not install until all the others are installed. Restart PC as well

    I am trying to manually install the updates to a server on a closed network. No internet access. Install instructions state to install "clearcompressionflag.exe" first. When I double click on it, nothing happens. So I tried to install KB2919422 as it states to install first, but I then get the following error: "The update is not applicable to your computer." Has anyone had this problem and know the solution?

      @Dennis: This update is applied only to Windows 8 (not to a server). A troubleshooting guide for the error message "The update is not applicable to your computer" can be found here.

    I tried MS automatic updates on my win8 notebook and leave the it connected with the power adapter. These prerequisite files never come into my computer over the course of the last 16 months. So, I tried downloading each file manually and selected Save. When I try to install each one in the correct order, I get: "This update is not applicable to your computer". I also tried Restoring the HDD OS. I sent the notebook to ASUS for this problem and asked for it to be upgraded to 8.1. It was returned with win 8. All they did was run Recovery Reset. There is no way I can update from win 8 to 8.1. Although the System shows "windows is activated", I suspect this windows OS is not genuine.

      @Ronald Quan: I believe that the "not applicable" error is displayed on computers with VLK keys. According to MS the only way (if you have a VLK key) to upgrade your computer to 8.1 is to perform a full re-install by using the Windows 8.1 ISO file.

      Hmm… its ok, i think your OS still genuine, if your win 8 is genuine, you can simply update into 8.1 using Store app. it will have a size around 3 GB..

      If you want to update to Windows 8.1 Update, YOU NEED WINDOWS 8.1 :)

      Windows 8 —–> upgrade to Windows 8.1 ——-> update to 8.1 Update 1

    Use the following script to do it all with one reboot:

    wusa.exe Windows8.1-KB2919442-xXX.msu /quiet /norestart
    wusa.exe Windows8.1-KB2919355-xXX.msu /quiet /norestart
    wusa.exe Windows8.1-KB2932046-xXX.msu /quiet /norestart
    wusa.exe Windows8.1-KB2937592-xXX.msu /quiet /norestart
    wusa.exe Windows8.1-KB2938439-xXX.msu /quiet /norestart
    wusa.exe Windows8.1-KB2949618-xXX.msu /quiet

    hi there, thanks for your blog!
    I've tried everything online and nothing worked for this update!

    I've followed your steps, all the update packages were installed successfully EXCEPT for the 2919355 one! What the hell is Microsoft doing???

      MS have re-released the 355 update
      re obtain the file from download center and try again
      and it should work for you
