In Windows. Don't lose that context.

In a system that fully supports feature X, feature X can be reasonably
used even if it's of no particular benefit.

In a system where use of feature X creates trouble, and where 26 years
of worldwide experience says that it's not necessary, it's not a good
idea to encourage its use.
