I've finally installed the Windows 7 that I've downloaded. There's at least a new feature that you can see at the very first time you install and run Windows 7. That's the homegroup, wow.. now you can create little communities of Computers! See the screenshot for more explaination.
And ofcourse, if you want to give it a try, you can do so:
Btw, this is my installation log:
VPC: 512MB RAM, 20GB Virtual HDD
Start Installation: 10:39pm
Abort Installation: 10:53pm
Reason: Too slow
VPC: 1GB, 20GB Virtual HDD
Put over night to install
And wake up in the morning, everything is up, but it take ages still to start the very first time.
