Routing compartments and Windows 7

Explains some relics of routing compartments in Windows 7.

In an old article by me here on WindowsNetworking.com, I mentioned a networking feature called routing compartments that was supposed to be introduced in Windows Vista.

Unfortunately that feature got cut before RTM.

Funny thing is, on Windows 7 there are some commands that have to do with routing compartments.  Examples of such commands include:

Ipconfig /allcompartments

Netsh interface ipv4 show compartments

Netsh interface ipv4 set compartment…

The first two commands produce what looks like valid output.  The third command returns the error "Incorrect function".  What's up?

Unfortunately the /allcompartments switch of Ipconfig and the set/show compartments commands of Netsh are just relics of the earlier plans of supporting routing compartments in Windows Vista.  So while some of these commands produce what looks like valid output, it doesn't mean anything useful.

Bottom line: routing compartments were NOT re-introduced in Windows 7!

I wonder though how many other relics there are in Windows of features that were planned but got cut just before RTM? Hmm…
