This will undoubtedly be useful to a few people.

But I'm not sure if selection of instruction set should not be better done by the compiler at
compile time, not at runtime. This should give the best possible performance (at the expense of
different .exe versions). Or is this more useful for choosing the right version of .exe?

Or is its usefulness as getting an ID of the computer - for which the serial numbers of other
components like hard drives (perhaps in combination) or cookies might be a better bet?

And of course it would need updating (from 2008) and full 'Boostification'. Header only very
strongly preferred of course.
