If you launch the DeviceEmulator by hand, those instances show up in the Device Emulator Manager in the "Others" node as GUIDs. They aren't exactly user-friendly, but they are the most reliable way of uniquely identifying an emulator instance.
There are two things you can do to help identify running emulator instances:
- Right-click on a GUID in the Manager and pick "Bring To Front". That will show you which emulator window corresponds to which GUID.
- When you launch the emulator, add one more command-line option, /vmname. The string that follows the /vmname option will appear in the Manager in place of the GUID. ie. "DeviceEmulator.exe xip.bin /vmname BarryPocketPC" will show up as Other/BarryPocketPC in the manager instead of Other/{...guid...}.
