After waiting 24 hours, Microsoft has finally released the ISO images of Windows 8.1 Preview. Now, people who are not MSDN or TechNet subscribers can install the new version of the operating system and test.

Microsoft announced Windows 8.1 last night during BUILD 2013 keynote at the Moscone Center in San Francisco. Being a preliminary version, it is recommended that you should use virtualization software as it avoids the risk of losing your data.

The ISO images (32 and 64 bit) are available in in Arabic, Chinese Simplified, Chinese Traditional, Korean, French, Japanese, English (United States), Portuguese (Brazil), Russian, Spanish, Swedish, German and Turkish. The minimum system requirements are same as Windows 8: 1 GHz processor, 1 GB (32-bit) or 2 GB (64-bit) RAM, 16 GB (32-bit) or 20 GB (64-bit) of free disk space and DirectX 9 compatible graphics card.

Microsoft has also provided information about how to create DVD or USB flash drive, in case you want to upgrade Windows 8. Remember, you cannot uninstall the update, but can only restore the factory settings of the system. As mentioned, the best way forward is to create a virtual machine.
