FAQ
Reader questions
Why does iTunes show an error immediately after I update Windows?
Windows updates can temporarily modify system permissions or remove compatibility shims that iTunes relies on. Reinstalling the latest iTunes package from Apple usually restores the necessary components and resolves startup failures.
