The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

If the Apple Mobile Device Service (AMDS) is installed on your system, you may need to manually start the service, then set the Service Startup type to Automatics so that the service can launch when necessary. Should you be unable to find the service in the list of services on your computer, or be unable to start the service, the article linked below also details how to go about completely removing AMDS in order to allow for a proper reinstallation.

The next article linked details a number of steps to help attempt to prevent any such conflict, and methods for isolating security software as the source of the issue, as well (starting with the "Configure your software" section).
