The beta is available in English (32-bit and 64-bit), German (32-bit and 64-bit), Japanese (32-bit and 64-bit), Arabic (32-bit and 64-bit), and Hindi (32-bit). Once you have the .iso image downloaded, I recommend you use IMGBurn to burn it to a DVD. The beta supports clean installs and Windows Vista SP1 to Windows 7 upgrades. You can only install the Ultimate edition. You should receive a beta key by e-mail sometime after you download the build. Microsoft gives the following minimum hardware recommendations for the Windows 7 Beta (and notes that they can change before the final):
•Processor: 1 GHz 32-bit or 64-bit processor
•Memory: 1 GB of system memory
•Hard drive: 16 GB of available disk space
•Video card: Support for DirectX 9 graphics with 128MB memory (in order to enable Aero theme)
•Drive: DVD-R/W drive
•Internet connection (to download the Beta and get updates)
