User-specific issues

If the issue only happens in one particular user account:

Create a new iTunes library to see if the issue occurs in a new library. If using a new iTunes library resolves the issue, recreate your old library in your new one.
To change back to your original library, close iTunes, and then hold down the Shift key on your keyboard while you reopen the program.

If the issue persists:

Check for issues with content files. Audio files can sometimes cause iTunes to quit unexpectedly or stop responding when the program is analyzing gapless playback information. To determine which file might be causing the issue, follow the steps below:

1. Quit iTunes.
2. Navigate to the iTunes folder:
   Windows Vista: C:\users\username\Music\iTunes
   Windows 7 and Windows 8: C:\users\username\My Music\iTunes
3. Move the iTunes Library.itl file to your desktop.
4. Open iTunes. Your library will be empty.
5. Press the Control and B keys on your keyboard to open the iTunes menu bar. Choose File > Add Folder to Library.
6. Navigate to the folder where your music is located:
   Windows Vista: C:\users\username\Music\iTunes\iTunes Media
   Windows 7 and Windows 8: C:\users\username\My Music\iTunes\iTunes Media
7. Choose an artist, album, or song to add to the library and drag it into the iTunes window.
8. Wait for iTunes to successfully add the item to your library and perform the gapless playback scan.
9. If the scan is successful, continue adding songs to your library.
10. If there's an issue with one of your files, your issue will reappear after you add it to the library. If it reappears, start over with these steps, being careful not to add the files that caused the issue.
