Freeware? 

This is a freeware?
AFAIK, most of microsoft software that are parts of windows operating system, for example, windows media player, they are distributed as if they are windows update components themself.
According to the EULA, to install those windows updates, you must have a legal licensed copy of microsoft operating system.
In other words, it allow you to install the updates only on a licensed copy of microsoft OS.
As it is a part of windows update, so it shouldn't be called freeware?
