When your iPhone is updated to a new OS, it may have no access to your Windows 11/10/8/7. But this can be eliminated by authorizing your PC using iTunes. Here's how:
- Start the updated iTunes on your PC Windows 10.
- Go to its "Account" on its menu bar.
- Head to "Authorizations" > "Authorize This Computer".
- Input the password and click "OK".

Way 8: Remove PDF files
Theoretically, iTunes is unable to read the files in PDF format. So, an unknown error occurred (-54) if you synced some purchased books with this tool. Now, please use the "Share" button on iBooks to email them to your own. Next, remove all the PDF files from your device.

- On your computer, go to the taskbar to hit the "File" sign.
- The "File Explorer" will open; please go to the "Music" folder.
