title: CreateProcess from memory buffer
body: <p>I can use CreateProcess to launch an EXE. I want to have the contents of an EXE in a memory buffer and do CreateProcess (or an equivalent) on it without having to write it to a file. Is there any way to do that?</p>
  
  <p>The backstory : we make games. We send a plain EXE to our distributors, which then wrap it using their favorite DRM and sell it to their users. There have been instances where users find crashes. Most of the crashes take 5 minutes to fix, but the patch must go through the distributor and it may take several days, even weeks. I can't just send the patched EXE to the players because it wouldn't have the distributor's DRM. I'm thinking of distributing the real game EXE inside an encrypted datafile so what gets wrapped (the external EXE) just decrypts and launches the real EXE. This way I could safely distribute a fix without disabling the DRM.</p>
