Different icon for XP and Vista

I often run multiple VMs at once - Parallels changes the icon if the VM is windows or linux, which is great to easy identify which machine you're switching back to. When running XP and Vista at once though, the parallel icons look identical.

Is there anyway to change the icon for a specific machine?

 

It shows only Windows and Linux, not type of OSes,
Actually only OS family is showing not OS type

 

Is there a way to customise it per VM?

If not, how can I submit it as an official request?

 

Probably it is better to submit official request

 

What is the procedure for doing this? Should I just raise a support ticket?

Cheers

 

Yes, create support ticket, please

 

Wait nevermind I found an excellent solution.

Parallels Desktop Menu -> Preferences -> Apperance Tab. Select "Live Screenshot" for the Dock Icon. This also affects the cmd-tab icon.

This is even better.
