Everything below still applies to the RC1 build 7100. The proof-of-concept code still works as-is. Nothing has been done to address any of this. Microsoft apps like Explorer.exe, Calc.exe and MSPaint.exe are still "blessed" with something apparently too dangerous to give third-party developers yet not dangerous enough to stop malicious software from abusing. MS still haven't responded to repeated offers to give them full details. As all of this is apparently a non-issue I'm considering putting the proof-of-concept exe/source online, but not sure yet if that's the best thing to do. I still haven't fixed all the typos on this paged or trimmed it down as I've been coding instead (plus there were those two weeks where I did nothing but play Resident Evil 5 on my 360).
