I fully agree with Ged. There is no reason to think "I won't do something a better way because it's implemented poorly in Win2k3, and ROS's official target is Win2k3". All what is said applies mainly to the kernel, and ideally in future our Win32 subssytem should have shim support for compatibility modes, and should share as much nice arcitectural features from Win7 as possible.

Wine can do that as they only provide usermode. (we actually allow something slightly along these lines by allowing the user to decide whether they're running on a server or workstation. It's an option in one of the cpl applets)
If you did what Wine do then the user would expect to interface with a Windows 7 kernel too, meaning they would try to install drivers for said version.

What I meant is that you must advertise as a certain version for the kernel so the user knows what they're dealing with.
However this does not stop you from adding features of the later kernels, nor does it stop you from adding services and APIs from later versions. The more you add the more likely you are to run more modern software.

In fact, my point about full win2k3 compatability being up for discussion at the kernel is directly related to this. I think you _should_ be adding features from the newer kernels where possible. This will greatly reduce the amount of work required if the decision is ever made to leap to the NT6 kernel. however you must advertise to users that it's still an NT5.2 kernel so any drivers required will load.

This policy is inconsistent with the fact that we advertise reactos as win2k3 sp1. Otherwise we should as well provide a config applet to let the user choose that, as wine does.

The target is only win2k3 in the kernel. Everything else is open to discussion (in fact, IMO even the kernel compatibility is open to discussion)

You should, and must, provide as much functionality as possible with the latest versions of Windows.
You can still provide many of the capabilities of Windows 7 using only an NT5.2 kernel. It's only the internal architecture which limits this, and in terms of many win7 capabilities, this kernel isn't a limiting factor.

As our target is win2k3 sp1 compatibility,
