I don't know.
However, what this guy is saying might have an element of truth in it. As I understand it, Windows Vista and presumably windows 7 will perform a Windows licence check every time you run an exe. This is because some windows versions (e.g. Vista Starter edition) only support running 3 non-system .exes simultaneously. If you try to load a 4th, then the application will fail to load due to a licensing error.
It wouldn't surprise me to see that the same licensing code is present in all versions of Windows - as it is a variant of the Systems Groups Policy code. After all, Vista has a 'reduced functionality mode' if there is a problem with the activation, that will let you run internet explorer, but nothing else. And if you try some trickery to try to get IE to launch an exe (e.g. by browsing to a local directory) then the application will fail to load.
If it is the case here that W7 has an extremely sophisticated licensing system, that is checked before starting an executable, then it is conceivable that by bypassing the checks, the performance of the OS can be improved.
