Microsoft decided to move the ICMP controls for the Windows Firewall in Vista. Why? I couldn't find a damned reason for it. They took the ICMP controls and moved them into some "advanced" MMC panel. Oh...and get this...they managed to add a URL where the controls used to be -- so it wasn't a space issue.
I tried Windows Vista in a virtual machine. Had to allocate 2GB of RAM for it. Video playback in the VM was just awful. This is on a quad-core host machine too. 8GB of RAM. Plenty of resources...but Vista couldn't play the video.
Fortunately, Windows 7 is around the corner. Hopefully, it plays better in a virtual machine than Vista. Ugh.
