On January 9th, the Windows 7 Beta will be available for Windows enthusiasts to download via the Windows 7 page on Windows.com.

The Windows 7 Beta will be available in English, German, Japanese, Arabic, and Hindi, and each language will be available in 32-bit and 64-bit versions (except Hindi which will only be available in 32-bit). Because the Windows 7 Beta will be offered download-only, it will be provided to you as an ISO image (an .iso file) that you download. After downloading either the 32-bit or 64-bit ISO image of the Windows 7 Beta, you will be required to burn the ISO image to a DVD to install Windows 7. So you want to be sure you have a DVD burner before spending the time downloading the ISO image.
