Yesterday, one of my customers called me and told me that he received an error Invalid security token when updating Windows Media Center on Windows. I had never heard of this problem, so I did some research on this error message and discovered that it could be caused by a poor or corrupt Windows Media Center library. So I decided to rebuild the Windows Media Center library.

Invalid security token

The Library folder is a file protected by the system. We must first enable Show hidden files and folders and Show files protected by the system.

  • Go to the Windows Menu screen 8
  • Type Folder Options and select Settings and click Folder Options
  • Now click the View tab and search Hidden Files and Folders.
  • Then click Show hidden files, folders and drivers & Turn off Hide protected files from operating system
