Sorry, I don't know much about trimming this OS - I was just shocked to see that 21GB size in your post.
WinSXS could one of the main ones. My windows is 17gb, but it was only installed a month ago, over time it will grow. My WinSXS is 6gb of that.
You can uninstall other stuff through control panel, programs and features, turn windows featrures on or off.
There is some useful information over at Black Viper's Website
is you want to tune it a bit more.
You could also consider shrinking your swap file if you have lots of ram and you don't hit it very often, but I'd do some research with that first. Or you could move it to another drive/partition.
You could also reduce the space used by system restore if you have that turned on. On large drives this can eat up as much as 10gb over a few weeks/months. If you drop it's percentage down you can keep fewer restore points and save space.
Fewer restore points could compromise your recoverability though..
