I have a program that still must target Windows XP (_WIN32_WINNT 0x501), as most of our customers still use XP. However, we have been shipping Vista for a while, and are now pushing Windows 7 upgrades. For the software to work correctly on the newer OSs, there are a couple operations that require UAC elevation. I have the elevation code working, but would like to have the UAC icon present on the buttons that launch the UAC process. Unfortunately, all of the options defined in Microsoft's UAC UI document require _WIN32_WINNT 0x600 or newer.

Is there any way to get the appropriate UAC icon (Vista and 7 use different ones) to show on the button while still being able to target XP (where no icon will be shown)? I'm using C++, but may be able to adapt a .NET solution.
