C++ is a superset of C.

Are you referring to Microsoft Foundation Classes (MFC)?

Umm...no. How can you maintain that Windows is written in C (which not
all of it is) when C has no concept of a class?

Nope, wrong again. Fact is, they *don't* have consistent look and feel.
Contrast the latest version of Office against something written in VB.
OE looks nothing like Outlook.

Got a source for that? Most C devs I knew back in the day didn't
immediately make the switch because of the learning curve involved.
Speed had little to do with it. At the end of the day, it all compiles
to assembly anyway.

It's because it's relatively easy to do.

Not anymore. The Visual FoxPro OLE DB provider is written entirely in
C++, for instance.

Again, got a source? I know of quite a few games that are written in
C++ (MSFT's Halo, for instance). A lot of games take advantage of
DirectX, and though it's possible to use DirectX with C, it's a major
pain in the posterior.
