iTunes for Windows doesn't open after upgrading in Windows Vista, Windows 7, or Windows 8
Sometimes a newly-installed version of iTunes for Windows won't open, even though it appears to be running in the Windows Task Manager. (To view Task Manager, right-click an empty area of the taskbar and click Task Manager, or press Ctrl+Shift+Esc (or Ctrl+Alt+Delete) and click Task Manager. You can see iTunes under the Applications tab of the Task Manager.) This symptom could be caused by an unusable iTunes configuration file.
