    Affected if Version is 12.0.x or earlier (before 12.1)
  3. Check iTunes version
    Open iTunes, go to Help > About iTunes. Note the version number.
    Affected if Version is 12.9.3 or earlier (before 12.9.4)
  4. Check iCloud for Windows version
    Open iCloud control panel or Windows Settings > Apps, find iCloud for Windows and check the version.
    Affected if Version is 7.10 or earlier (before 7.11)
