OK, same for me update from the UI on XP Pro and win7 32bit and no problem, so don't know if it might be limited to Vista 64bit.
Hopefully your dump file will help get to the bottom of it.
When updating using the GUI
I had no problems when updating my Acer
I had the BSOD problem on only one Dell Desktop
However the rootkit scan at boot caused problems on both of my Dells
