Hi Paul,

AFAIK backwards compatibility with API's is maintained so I don't think
there would be such a list. But don't take that as definitive.

However calling an API in an earlier Windows OS that was introduced in a
later version can crash the system. I've come across API's in this group
that will do just that, so well worth checking the 'reverse' of your
question.

MSDN Home MSDN Library Win32 and COM Development Development Guides
Windows API Windows API Reference Functions by Release

http://msdn.microsoft.com/library/de...us/winprog/win
prog/functions_by_release.asp

I don't know but would not be surprised if there are API's that will only
work in NT.

Regards,
Peter T

Hi all

Does anyone know of an inclusive list of APIs that were used in earlier
versions of Windows that are no longer compatible with WinXP?

Thanks in advance
