No, this compatibility mode is a big achievement of W7. I found out that
a lot of applications which would run under XP will perfectly run in W7
under this compatibility mode.
Otherwise they would have been lost.
Yeah, but they screwed up not having that work in all editions of
Windows 7.

Sincerely,

Gene Wirchenko
But they *did* include it in all editions of 7 and Vista.

Well, maybe not Windows 7 Starter, although I would think it's there
too. I just checked - it is.

You are correct. There is a stash in SysWOW64 of dll's from older
versions, as well as other software tricks, to avoid incompatibilities
with the latest system software and API. Compatibility mode uses the
appropriate set of those for the OS level you choose for a given
program.

Details are next to impossible to find; Google (at least in my hands)
mostly finds instructions on using it.
Just a "modern version" of "setver" ;-)

Huh? You told you that? This is just not a Windows 7 thing. Earlier
versions of Windows has this compatibility setting too. I don't recall
how far back it goes, but I am pretty sure it was in Windows 98 too, if
not earlier.

Whoa! That is totally different than what I am talking about! Totally
apples and oranges. I am talking about the compatibility setting under
Properties. I am not talking about the band aids that Microsoft has
planted in the x64 version to make it somewhat usable for 32 bit
applications. Don't confuse the two.

And what do you think I am talking about?

I've never noticed this before. Perhaps it has always been there but I
never saw it. I never needed it as well.
