One of the most used tools when fixing corruption for Windows Vista, 7, 2008 and 2008 R2 was the System Update and Readiness Tool (KB947821), commonly called CheckSUR.  The CheckSUR tool was an excellent way for most people to see what corruption had happened on their store, and potentially fix that corruption if the tool contained the payload to do so.  I’ve written in the past how to use this mechanism to also fix corruption when the CheckSUR utility doesn’t include the payload for your files to “fool” CheckSUR into resolving the problem without needing to do all sorts of whacky permission changes (http://blogs.technet.com/b/joscon/archive/2010/05/26/using-checksur-and-update-packages-to-fix-corruption.aspx).
