2) Active response. Microsoft, on purpose, introduces new
software technologies. For example, there is a possibility
they will invent something to replace .NET. Software will
go on sale, and, it won't run on WinXP, because the new
library technology (whatever it turns out to be), won't be
available for WinXP.

I think they've already done that. I sent someone a file compiled
with Net 4.5--oops, we couldn't get it to run on his XP box, nothing
in Windows Update to support it. (Fortunately I hadn't actually used
any 4.5 features, that was just what I had the compiler set for.
Downgrading to 4.0 worked fine.)
