If you as a Windows 8 user decide to install the Windows 8.1 Public Preview version, remember that you will have to reinstall your software, when you rollback to Windows 8 or move over to Windows 8.1 Final RTM version.

If you install the preview version and need to install the final RTM version, when it is released, during this upgrade from the preview to final RTM version, while your data will remain intact, you will later on need to reinstall all your apps.


Windows 8.1 Preview will expire on January 15, 2014. Uninstallation is not supported on Windows 8.1 Preview. You may want to read this post on Windows 8 to Windows 8.1 Preview Upgrade Policy before you proceed. So rather than upgrading your Windows 8 to Windows 8.1 Preview, we recommend that you install Windows 8.1 Preview on a separate partition.

If you are on Windows RT and have installed a language pack, please don’t install the Windows RT 8.1 Preview at this time. A fix is coming.

If you’re running Windows 8 Enterprise, you’ll need to install the preview using the ISO. Go here to learn more about Windows 8.1 Enterprise.

    I decided to purchase windows 8.1 do I install it from the DVD over windows 7 professional please, also what about the drivers

  • Anand Khanse

    Personally, I prefer to back up what I want, and then go for a fresh install, rather than an upgrade. Search for both options here, and you will get some information about each. The drivers will get automatically installed, so you do not need to worry much about them.

  • Buck

    Thanks Armand for the advice, I’ll do that
