There's a number of #defines you can set to tell the headers that you're
targeting various versions of Windows. WIN32_LEAN_AND_MEAN has been a
favourite, and WINVER is the "master control" for what version of
Windows you're targeting.

The whole "what controls came with which version of Windows or Internet
Explorer and how can I check for them and install them in my installer"
thing is rather annoying, to say the least. To install the later stuff,
you need the Windows Installer -- but the earlier systems don't even
have *THAT* installed, and the installer redistributable requires a
reboot to become effective. Bah!

With something as simple as a mesasge constant, you're safe, though, as
that message just won't get sent to you on earlier versions, so that
switch case won't get hit. No compatibility worries there (unless you
require mousewheel for accessing needed functionality in your program).

You probably also want to go to the Windows developer download page on
MSDN and download/install the Platform SDK (if you haven't already gotten
it through a regular MSDN CD) which has rather more updated headers and
libraries.

Cheers,
