Windows Vista SP1 vs SP2 Comparison
 

So… Service Pack 2 arrived with not a lot of celebration, not much has been really mentioned about it at all anywhere. Being who I am though I like to know things, so I decided to run a whole bunch of tests before and after the upgrade and compare them to see just what, if anything, might have changed.
