Actually, I think you made that too easy. Microsoft itself has lots of legacy drivers - probably thousands. Changing them would require finding, recompiling, retesting, and redistributing all of them at best. That's certain to be expensive, and may not even be possible in all cases, so you're probably not going to do it.

So how would you fix this without changing any drivers from any vendor that have already been released?

Also keep in mind that this is a minor convenience feature that most people will rarely see, so you probably don't have a massive budget.
