ReactOS does not seem to report the correct OS

[oldman]

When trying to install Internet Explorer I get this message "Internet Explorer 8 is not supported on this operating system" ( see http://www.reactos.org/wiki/images/4/40/IE.png) and when installing the correct drivers for the mother board I get this message "The Intel(R) Chipset Software Installation Utility requires a supported chipset platform running on a supported operating system." (see http://www.reactos.org/wiki/images/f/f3/Intel.png). Both programmes terminate at this point.

So are these programmes looking for something that is not present in ROS?

IE8 issue is reported in bugzilla iirc, there you can find the technical details.
The driver issue could be related too.
Basically some apps reads in Windows registry which OS version is installed( XP,Vista, Xp sp3,etc..) and stops its installation if the OS is not "good enough".
ReactOS has a registry key reporting XP version and seems they need at least a XP SP3

ReactOS is detected as Windows 2003, so it needs to be SP2 instead of SP1.
