Second question that was asked was the following:
"Another one: Why is the /passive switch not supported for updates. With update.exe, there was a "/passive" switch that was IMMENSELY USEFUL when installing batch updates via a script as it was UNATTENDED but displayed the progress. WUSA only has the /quiet switch but does SILENT unattended installs. Please also support the /PASSIVE switch for future updates perhaps beginning with Windows 7 SP1. Right now I am forced to use a command prompt/cscript to install MSU updates to I can see its process has exited and the next one has begun installing."
I will leave this one short and sweet: This is something we are looking at for future releases.
Any other questions, ask away. Aside from that I am going to work on posting some servicing mechanics in a blog entry in the near future.
