I am playing a game called Starcraft II that restricts me from running multiple instances. However, when I run a second instance sandboxed in Sandboxie, I can do so perfectly fine. What might account for this? How might I replicate this behaviour?
I realise that this is a very vague question, but I'm not really sure how else to ask. How do games typically detect & prevent multiple instances from running? I have heard that a
CreateMutexW hook often does the trick, but even if this were the case here, I don't know what the the mutex that Starcraft would create is named.
