windows81-00If you’re itching to take a tour and try the new features of Windows 8.1, including automatic app updates, booting straight to the desktop, (up to) four app split screen, radio, a health and fitness app, 3D printer support, and more, you can download it now.

Note: If you’re using an English version of Windows, you can only install Windows 8.1 Preview from the Windows Store if your OS base language is English (US)

If you do not have a Windows 8 disc handy, create a Windows 8 USB recovery drive in case anything goes wrong in the upgrade process and you need to recover Windows. To update your installation of Windows 8 to Windows 8.1:

  1. Follow this link and click “Get the Update” Download Windows 8.1
  2. Double click Windows8-RT-KB2849636-x64.msu to begin setup
  3. When prompted, click Yes


  1. Once the installation is complete, restart your computer
  2. When prompted, click Go to Store (if you’re not prompted, press the Windows button, type Store, and click Store; click Windows 8 Preview)


  1. On the Windows 8.1 Preview screen, click Download
  2. Once the download is complete, restart your computer

If all goes well, you’re at Windows 8.1; if it fails, let us know in the comments. Now you can boot straight to the Windows desktop—if that’s your preference.

    .msu file showed successful and I restarted after that!
    In verbose message will restarting it showed that it was updating (10% – 100%)
    But after restarting, I never got any windows store pop up!
    I used “Expand -F” Cmd to install it via cmd line, but this no windows store pop up,
    Still i’m in windows 8 pro x64!
    I’m literally waiting for the .iso file!!

      The article does say if store doesn’t automatically come up then you need to open it manually (search for ‘store) and then download…

    “The update is not applicable to your computer”. I’m running a legit Win8. What’s up?

    I should have stayed with Win7. I should ask for a refund for Win8. After eight tries I finally downloaded and installed 8.1. What a mess. Every time I boot my machine it changes settings and it’s an adventure to make things work.
    Win8 really doesn’t amount to much except aggravation. Typical MS upgrade. Most changes are under the surface and not noticeable. So to make it look new they change the names and places of things just to give the appearance of something new that’s worth $119. How many times have they changed the name of File Manager for no reason?
