Changing the computername per sandbox?

[kevinrocksman]

How would I go about changing the computer name that an application sees when running in a sandbox?

[Syrinx]

I'd likely just open regedit sandboxed and navigate to the keys to edit them both under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ComputerName

It should also be possible to open sysdm.cpl sandboxed then change it but I'm not sure how that would work out as it will want you to reboot before applying the change and that won't work in the box so it won't ever change the active one.
