How does the @OSVERSION function determine the OS?

[ScriptingSteve]

I have a script running at logon for approx. 12000 users. I use @OSVERSION to limit execution to Windows XP computers. The script is aborting on one computer, claiming it is "WIN_NT4" when it is most obviously XP.

Something that AutoIt reads to fulfill the @OSVERSION function is obviously corrupted, and if I knew what these were, I could analyze the corruption further.

So,

What registry values, etc, are referenced by the @OSVERSION macro?

Autoit inturpits the values of OSVERSIONINFO (http://msdn2.microsoft.com/en-us/library/ms724834.aspx) if nothing has changed since the source was last relased -

OS_Version::OS_Version()
{
    int             i;
    OSVERSIONINFO   OSvi;                       // OS Version data

    // Get details of the OS we are running on
    OSvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
    GetVersionEx(&OSvi);

...

It uses the Win32 API so if your computer thinks it the wrong OS its got identity problem. Try talking to it and explaining that winxp isn't really that bad

Thanks for your assistance. Basically, the computer reporting this issue is simply wacked.
