  • Will the update work for those of us still running Windows 8? I've not updated to 8.1, yet. Must I update to Windows 8.1 first before getting this update?

    I am running Windows 8 Pro and have had problems in the past trying to update to 8.1. It's a volume license copy on a computer I bought from a former neighbor. It won't allow me to update as it tells me to contact my administrator or something like that. I own this computer. Any help will be much appreciated.

    Thank you very much.

  • @lisa yes you need to install win 8.1 first.Same was the case for me,so i had to fresh install windows 8.1..Actually upgrading to 8.1 is not allowed for volume license customers.

  • How big is the update? It seems to be taking a while to download from Windows Update. From the Microsoft website it didn't take that long.

  • This is ridiculous! I now can't activate Windows 8 Pro after installing a new SSD into my system. This new SSD is what I installed Windows 8 on. I just read somewhere that Windows might not properly activate after a hardware change. What? My product key is legit and activated with no issues before.

    Please help, I am trying to do the right thing but I'm not seeing any options on what I can do. Also, please don't suggest for me to illegally download anything, as I already own a legit key.


  • does this include the start menu and the windowed windows store apps?

  • Can This Update Work In For Windows 8.1 Pro
    Or This Only For RT And This Update Can Not Be download from widows update ???

    @Lisa Millton
    According to Microsoft, Windows 8.1 with Update 1 will be available for Windows 8 users through Windows Store.

    There are 5 updates and the biggest update is about 700MB in size.

    @Lisa Millton
    Regarding your other problem, try to remove the product key and then re-insert it using System Properties. Now try to activate Windows again. If you still face problem, try the activate by phone option.

    No. These features will come in future updates.

    Yes. It'll work in Windows 8.1 Pro as well. Microsoft is rolling out this update for all countries. If its not available for you in Windows Update, you can try to download it manually using above mentioned links.

  • Ya the only website which gives the right news, in a right time with clarity. VG, Could you please guide us how to integrate these updates to Existing Windows 8.1 iso. could it be possible? .

  • VG

    ^^ Thanks. You can try following 3rd party tool:

    Also check following:

  • How much space did the update take from your hard drive after installing it?
    I'm wonderng because it took almost 5GB on my system.

  • VG

    You can try to clean temp files:

  • I was Blue Screen after Installing this update :'(
    I used Windows 8.1 Enterprise with MAK Keys. :'(
    Help please...

  • Please let me know what happens if the update files are not installed in the right way as you have told. will mine OS damage....

  • Why couldn't they just call it Windows 8.2?

    Between "Service Packs," Hotfixes," and "Update Rollups," this company continues to demonstrate that their code is nothing but one big House of Cards. :-(

  • Anyone here using Bins by 1UP Industries and have installed Update 1 to their PCs? I was wondering if Bins still works properly after Update 1 has been installed. I have not yet installed the Update because I want to ensure that Bins will not be adversely affected by it. My PC is working great right now and I don't want it to get screwed up courtesy of Microsoft.

    Thanks fr the info.

  • I can't install the update. I ran the Windows Update Troubleshooter, install the update manually, uninstall any tweaks (UXstyle, Aero Glass for Win8.1, etc). Last time I tried, it reached 99% and then said it failed. I bet that since this was a display PC in a store someone tweaked it. I'm running Windows 8.1 x64 (upgraded from Windows 8) by the way.

  • I have windows 8.1 full install DVD 64 bit. Installed it a few days ago and today I downloaded the files mentioned above, tried to install the following files in the order as mentioned and this is what happened;

    #1- KB2919442 - Windows said its already installed!
    #2- KB2919355 - Windows said its already installed!
    #3- KB2932046 - Windows said its already installed!
    #4- KB2937592 - Windows said its already installed!
    #5- KB2938439 - Windows said its already installed!
    #6- KB2934018 - Windows did accept and install this update.

    My question is, why did it not accept the other updates? VG can you please explain? Seems rather unusual since I did all my updates manually and not automatic download and install!

  • VG

    ^^ Microsoft has temporary suspended distribution of Update 1 for Windows 8.1 Enterprise users because of some issues. They'll start distributing it again very soon with a patch.

    Did you install them in correct order?

  • How to Slipstream Service Packs into Microsoft Windows 8.1?

  • Thanks for the message "Microsoft has temporary suspended distribution of Update 1 for Windows 8.1 Enterprise users because of some issues. They'll start distributing it again very soon with a patch." VG!

    Please update whenever Update 1 will available for Windows 8.1 Enterprise x64.

    Further, should I download "KB2919442" pre-requisite update with Update 1 to update on an offline PC?

  • I installed it few days ago and after rebooting I saw nothing but black screen with white cursor visible when moving. I couldn't log into my PC, it didn't respond to anything (clicking, input from keyboard, power button, etc.). I used the Windows installation DVD to restore my system to previous state, but the problem re-occured as Windows tried to install the update again. Have you (or anyone) experienced such issue? How to fix it? I use Windows 8.1 Pro x64 with all the previous updates installed and latest drivers for my PC. Greetings

  • VG

    ^^ I didnt face such problem in any computer. If such problem occurs in future, you can start the computer in recovery mode and then use System Restore option to restore Windows to an earlier state.

  • VG how can I get download windows 8.1 ISO if the windows 8 upgrade assistant doesn't work?

  • VG

    ^^ Try following:

  • As you have mentioned earlier that ^^ Microsoft has temporary suspended distribution of Update 1 for Windows 8.1 Enterprise users because of some issues. They'll start distributing it again very soon with a patch. ^^

    Then, how Microsoft has provided "Windows 8.1 Enterprise x64 and x86 with Update New!"?

    What we will need to download new ISO every times?

    How can I update the Windows 8.1 Enterprise x64 ISO with Update 1?

  • VG

    ^^ The new update and updated images are available now.

  • @VG - I have already downloaded Windows 8.1 x64 and Update 1 when it's available publicly. But don't wish to download new ISO even just for Update 1.

    I asked you because you mentioned in your earlier post that "Microsoft has temporary suspended distribution of the Update 1 for Windows 8.1 Enterprise users because of some issues." so just let me know if it will be updated now.

  • I got a BSOD and blank after installing and restarting device.
    How to install it? Install 1 update and restart, or install all update and restart
    UPDATE: After i'm check again, there is a new update on "Service Pack Update" download page. It's KB2959977, what is the function?

  • I have downloaded & installed Windows 8.1 Update 1 from here. But the KB2919355 took 30+min. All are working very nicely. Thanks VG!

  • Hello VG!

    Today, I have noticed that Microsoft had made changes in Update 1 constituents by adding two files clearcompressionflag.exe and Windows8.1-KB2959977-x64.msu on May 05, 2014.

    What I should need to download all files again as I have downloaded Update 1 on April 16, 2014 or only 2 new files would be enough?

    Let me know if the Update 1 is available on this URL compatible with Windows 8.1 Enterprise x64.


  • VG

    ^^ Yes. The link is correct and you should first try downloading only new files.

  • Thanks VG!

    As you have advised, I have downloaded only new files and installed. Now, after updated Windows 8.1 with Update 1, what should I need to download all updates for an offline (no internet) notebook?


  • VG

    ^^ Only the mentioned updates in above topic.

  • VG! I mean, what should I need to download every updates available after updated an offline notebook with Update 1?

    I think, Windows 8 series is an innovation specially for internet users.

  • VG

    ^^ When you install Update 1 in a computer, you'll obviously need to download and install all later updates.

  • This update 1 to windows 8.1 is excellent & more easier to use & is successfully installed on my windows 8.1 PC.
