Clearing Windows Media Player cache

During an MP3 re-tagging session I was becoming frustrated that WMP wasn't refreshing and showing the tag changes I had made to the files on my NAS. The NAS is a uPnP server for media around the home and WMP is just one of the clients that render from it.

Restarting WMP didn't help, nor did re-starting the machine, so after a bit of Googling I found this post that help me crack it. Essentially you have to delete the WMP databases (local cache) which forces WMP to reload from the uPnP server.

NB: I had to stop the Windows Media Player Network Sharing Service for this to work (it has a read lock on one file)
