If I were you, I would not mess with the WinSxS folder because it contains system files. This is a link that may help you understand the folder better (why it's there and what it does): Disk Space - Engineering Windows 7 - Site Home - MSDN Blogs

If you have a 320GB or greater HDD then I wouldn't worry about the space anyways, as it's such a small percentage and a necessary folder for the way Windows is setup. This article refers to Windows Vista, but it applies to Windows 7 as well, Vista is just the OS in which they added this functionality.

No, you should NOT delete anything in there. This folder contains many core windows components, etc. that make Windows run.

When you install updates, different files are updated at various places inside the Windows folder and the backup of older versions are stored inside winsxs folder (many of them inside the winsxs/backup folder).

You should not worry about this folder. The size of this folder is not actually what it shows up but much lesser because lots of hard links are used inside this folder.
