For a couple of weeks I have been getting increasingly annoyed by my desktop PC (Microsoft Windows XP Media Center Edition Version 2002 Service Pack 2) no longer shutting down when I click on ‘Turn Off Computer… Turn Off’. It would close most of the active applications, but then stop mid-way through shutting down and then remain in an idle state. The only way to shutdown the computer was to go through the Turn Off / shutdown sequence twice each time. After a process of elimination I finally traced the culprit to a process named skypePM.exe.
