I don't know how to do a Screen Shot" ( never did it before ) however when I plug in my Uno R3 it reports correctly in the device manager as an Arduino Uno R3 under the Com port tab and when I plug in the Mega it reports an Arduino Mega 2560 with the little yellow ! symbol (Driver trouble symbol) But this is under the Other devices tab and not under the Com Port tab as it should and there is no com port associated with it. Yes there are ICSP pins too, for both uProc's... It Looks like a real Mega 2560, even to the useless reset switch (if one has a shield installed the switch is well protected and hidden)... I do hope this helps.
