Why is the Windowswinsxs directory so large?

I wanted to put some sort of content on here quickly, so here is a link to my teams blog which I wrote last year about a common question asked when it comes to servicing the operating system.  "Why is the \Windows\winsxs directory so large?"  The short answer is that it is really a "flat" of your Windows installation which means that its all of the files needed for you to use Windows without the need to put a CD\DVD into the drive every time that you need to add a new feature or update a file.

For more information on why its the size it is, see my old post here:
