So we can try this Windows 7 beta now, which is said to be better than Vista, and which we'll have to get used to anyway. Here a few tips which I may need when I find a machine to try it on, and which may help you too.
The official download seems to only work with IE 7, but if you get the direct link it does work normally. So with wget, that would be:
For the 32 bit version:
wget -c http://download.microsoft.com/download/6/3/3/633118BD-6C3D-45A4-B985-F0FDFFE1B021/EN/7000.0.081212-1400_client_en-us_Ultimate-GB1CULFRE_EN_DVD.ISO

wget -c http://download.microsoft.com/download/6/3/3/633118BD-6C3D-45A4-B985-F0FDFFE1B021/EN/7000.0.081212-1400_client_en-us_Ultimate-GB1CULXFRE_EN_DVD.ISO
