@Gunivortus Goos: You could move the shortcut to the “Startup” folder to achieve the same effect as putting it in the registry.

You may want to look into VirtualBox, which is also free and allows you to run “headless” servers designed for network access, among other nifty features.

Hy Ryan,
thanks for your answer.
I might not have been clear enough, I ment at starting the host system. I’ve put that line above in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
So VPC and the VM already start at start of the host system. Now I like to get it directly minimized.
Is that possible?

@Gunivortus Goos: You can try creating a shortcut which points to “C:\Program Files (x86)\Microsoft Virtual PC\Virtual PC.exe” -startvm E:\VPC\VirtualPC.vmc . Then changing the properties of the shortcut to “Run: Minimized”.

Is there an option to start the Virtual PC console AND the Virtual Machine minimized?

I’ve set it now to:
“C:\Program Files (x86)\Microsoft Virtual PC\Virtual PC.exe” -startvm E:\VPC\VirtualPC.vmc

but it shouldn’t be on the screen, because the VM will be accessed directly through the network.

@Prabhu: I’m not aware of a way to do that with the command line switches. There may be some third party tools available to do this though.
