Resolution

Start iTunes in Safe Mode

Open iTunes in Safe Mode to isolate any inference with plug-ins or scripts not manufactured by Apple.

1. Hold down the Shift and Control keys while opening iTunes. If performed correctly, you should see a dialog that says "iTunes is running in safe mode" before iTunes finishes starting up.
2. After clicking Continue, determine whether the issue you were experiencing persists in Safe Mode.

If you see the same issue while iTunes is in Safe Mode, proceed to the Create a New User Accountsection below. If you do not experience the same issue, consult iTunes: Troubleshooting issues with third-party iTunes plug-ins for steps on how to remove third-party plug-ins.

Create a New User Account

When troubleshooting a variety of issues, it can be useful to determine if the issue affects a specific Windows user account or all accounts. Follow the steps below to create a new user account in Windows Vista or Windows 7:

1. From the Start menu, choose Control Panel.
2. Open Add or remove user accounts (If using the Classic View in Windows Vista, open User Accounts. Then open Manage another account).
3. Select Create a new account and follow the instructions to complete the account setup process.
4. Once the new account is created, choose Log Off from the Start menu.
5. Log into the newly created user account.
6. Open iTunes and determine whether the issue you were experiencing persists in this new user.

If you see the same issue in the newly created user account, proceed to the System-wide troubleshooting section below. If you do not experience the same issue, consult the User-specific troubleshooting section below.

• Remove iTunes Preference files
  Some of the files that iTunes uses to store settings and preferences may be unusable and cause issues. iTunes has two folders where preferences are saved.

• Recreate your iTunes Library

If you iTunes library has become unusable, rebuilding it as described in How to recreate your iTunes Library and Playlists may resolve the issue.

• Check for content files with issues

  3. Move the iTunes Library.itl file to your desktop
  4. Open iTunes. You should not see any content in iTunes.

     • Windows Vista - C:\users\username\Music\iTunes\iTunes Media

7. Choose an artist, album, or single song to add the to the library
