  • is it available now ?? I get an error on Microsoft's website

  • I'm downloading now through Windows Store but it keeps failing. I've downloaded about 2.55GB of the 3.42 GB download (for my computer) but it is able to resume thankfully. Although it now seems to fail every 1% or so. I'm assuming that the Microsoft servers are probably clogged full of users also wanting to download. This could be your issue @ernest if you are already downloading.

  • There is no KB2871839 update, I found out by some googling and stumbling upon a Chinese forum.

    The correct update is KB2871389.

  • PS: Also keep in mind that Windows 8 Enterprise edition, Windows 8 installed using KMS activation and Windows 8 installed using MSDN ISO and activated using product key which allows multiple activation, can't be upgraded to Windows 8.1 using Windows Store.

    so how can we update to windows 8.1?

  • Is there any offline upgrade link for Windows 8.1 Pro ?

  • Hi VG, I've got a really specific question...

    I was experimenting with Dual-Boot, so I had to reinstall Windows when I was done. I used an OEM key from Dell to activate, then used my Media Center Key to upgrade. Afterwards, I was prompted that my key was already in use (On my First Windows install). I used SLUI 4 and Phone Activation to fix this. Will I be able to upgrade or not because of this? I haven't checked yet because I am at work, but I don't want to be dissappointed when I go home.

  • i already update KB2871389 i wait for 8 hours and windows store not show me the update to 8.1 what should i do? waiting?

  • No Update shown in the windows Store..
    haven't it released in India?

  • How to get offline update? That is download on one and install on multiple using
    DVD/USB drive?

  • In addition to above post, I have Windows 8 (OEM) pre installed on a laptop.

  • My windows 8 PC doesn't seem to think that I'm connected to the internet even though I'm reading this article and writing this comment on the same PC. Any chance they have given a manual download link for the update?
    Also, I have a 256 kbps broadband, that means downloading this update will take almost 36 hours. So I would like to get it from somewhere else.

  • VG

    Guys! Just wait for some time and there should be official offline download links available from Microsoft.

  • @VG check out the second reply, the one by Charles from microsoft

    ^^ It will. Microsoft has announced it earlier:

    One shift to note in Windows 8.1 is that we will be offering “full version software” at retail and online for download that does not require a previous version of Windows in order to be installed. The copy of Windows 8 that is currently available for sale at retail and online is an “upgrade version.” This shift allows more flexibility for customers in specific technical scenarios and is in response to feedback we’ve received. It will be easier for those consumers who want to build PCs from scratch, run Windows 8.1 in Virtual Machine (VM) environments, or run Windows 8.1 on a second hard drive partition.

  • Question. Do you need administrator permission to install Windows 8.1 from the Store? I'm guessing I do, but I want to make sure first.

  • Still won't work for me, I have 8 Pro, but still can't see the upgrade, tried every fix and patch available but still cant see the damn thing...

  • VG

    ^^ Try the direct command to launch Windows 8.1 update page in Windows Store. Check the NOTE given above.

    I was able to upgrade Windows 8 with a normal user account created at the time of Windows 8 installation.

  • Hello Brother!

    Can I install Windows 8.1 Pro along with Windows XP SP3 Dual Boot?

  • I currently have Windows XP SP3 with Windows 8 in my PC. Please suggest me how to make Windows XP available along with Windows 8.1. :)

  • VG

    ^^ Windows 8.1 will automatically detect Windows XP and you'll have a dual-boot system. Make sure to install Windows 8.1 on a different partition.

  • Don't be worried, Windows 8 users,
    Upgrade from Windows 8 to Windows 8.1 via Windows Store does not lose manufacturer's information. After upgrade to Windows 8.1, "Manufacturer" and "Model" retains in System Properties.

  • Can somebody please post a picture of what the store screen with Windows 8.1 download link looks like? I've been in that @#$ store many times now and I have to browse hundreds of irrelevant things all the time. I have no idea where to look; Is it under 'productivity' or 'tools' or 'security' or even 'entertainment'? A search for Windows 8.1 gives me 122 offers *related to* Windows 8.1, but where the heck is Windows 8.1 itself??

  • Its in there, just keep looking mate

  • is there way to upgrade for kms activated os without formating

  • I felt bad that I can't upgrade to Windows 8/8.1 directly from Windows 7 Ultimate. I Need to do clean installation because Upgrade option from Windows 7 Ultimate/pro/enterprise is only available for windows 8/8.1 pro. Why MS Did this? I don't need pro & I don't want lose any Game preinstalled by HP.

  • can somebody tell me why windows 8pro is not activate by dvd serial key

  • I have all my Windows 8 Updates up to date and get the message "No Important Updates At This Time" when I click Check For Updates.
    When I go to the Store Screen to Update to Windows 8.1, it goes to the Installs Screen with the Icon and the Downloading Toolbar appears. Seconds later, on the Installs Screen, the Windows 8.1 Icon stops and says that "The app wasn't installed - view details." When I click View Details a box says "Windows is getting your upgrade ready. You will be notified."

  • The download for windows 8.1 always begins but it never completes. Tired of trying now.

  • Will the drivers installed on windows7 will corrupt after installing win8 or win8.1?? I've dvd of drivers supporting win7,.................will it work on win8.1 or will i have to install 'em seperately from net??
