How can I determine which operting system I am running on (Win 95 or NT4.0)
Also, how can I check to see if Service Pack 3 is installed?

Please e-mail only..

I would use the GetVersionEx function...

And here is some sample code I found in the MSDN. To test for SP3 you may
have to check build numbers

#include <windows.h>
void main()
{
DWORD dwVersion;
char szVersion[80];
dwVersion = GetVersion();
if (dwVersion < 0x80000000) {
// Windows NT
wsprintf (szVersion, "Microsoft Windows NT %u.%u (Build: %u)",
(DWORD)(LOBYTE(LOWORD(dwVersion))),
(DWORD)(HIBYTE(LOWORD(dwVersion))),
(DWORD)(HIWORD(dwVersion)));
}
else if (LOBYTE(LOWORD(dwVersion))<4) {
// Win32s
wsprintf (szVersion, "Microsoft Win32s %u.%u (Build: %u)",
(DWORD)(LOBYTE(LOWORD(dwVersion))),
(DWORD)(HIBYTE(LOWORD(dwVersion))),
(DWORD)(HIWORD(dwVersion) & ~0x8000));
} else {
// Windows 95
wsprintf (szVersion, "Microsoft Windows 95 %u.%u (Build: %u)",
(DWORD)(LOBYTE(LOWORD(dwVersion))),
(DWORD)(HIBYTE(LOWORD(dwVersion))),
(DWORD)(HIWORD(dwVersion) & ~0x8000));
}
MessageBox( NULL, szVersion, "Version Check", MB_OK );
}

Call GetVersionEx(). To check for service packs, you'll have to parse
the szCSDVersion string -- it looks like "Service Pack %d", if an SP
is installed.

Cheers,
Felix.
