Window7 buzz is in the air, we have already seen ‘vista to windows7 upgrade’ details and cool official Windows7 videos. Here is the most important part of downloading and installing Windows7 on your computer. You can download Windows7 from Official Windows7 webpage on Microsoft website beginning Jan 09, 2009.
Windows 7 Beta will be available in download-only (no physical media) and available for a limited time to the first 2.5 million people who download the beta.
It 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).
The download file will be an .ISO file that you should burn on a DVD after the download. After you make your Windows7 Beta DVD get set with simple installation process. As pointed by Windows Blog, make sure you backup data on your existing Windows Vista computer before Windows7 install.
UPDATE - Direct Download links of 32bit & 64bit
