If you use iTunes to manage your music library and sync songs to your iPhone or iPad, you might occasionally run into the frustrating issue where iTunes doesn’t sync music on Windows 11.
You may notice that iTunes detects your iPhone but doesn’t transfer songs — or the sync process freezes midway without adding any new music.
Don’t worry. This issue is common and usually related to settings, outdated software, or corrupted sync data. In this guide, we’ll walk you through all the proven methods to fix iTunes not syncing music on Windows 11.
1. Check the Basics First
Before diving into deeper fixes, confirm a few essential things:
- Make sure your USB cable is working properly — try using an original Apple Lightning cable.
- Unlock your iPhone and tap “Trust This Computer” if prompted.
- Ensure there’s enough storage space on your iPhone or iPad.
- Check that iTunes recognizes your device (it should appear as a small phone icon in the iTunes window).
If these are fine but music still won’t sync, continue with the next methods.
2. Update iTunes to the Latest Version
An outdated version of iTunes often causes syncing problems.
- Open iTunes on your PC.
- Click the Help menu → select Check for Updates.
- If you installed iTunes from the Microsoft Store, open the Store → click your Profile → App settings → Get updates.
After updating, restart your PC and reconnect your device to check if syncing works again.
3. Restart Apple Services
Sometimes Apple-related background services stop working correctly, which prevents iTunes from syncing. Restarting them can help.
- Press Windows + R, type
services.msc, and press Enter. - Find and restart these services (right-click → Restart):
- Apple Mobile Device Service (AMDS)
- Bonjour Service
- iPod Service (if available)
- Once restarted, close iTunes and open it again.
Now, reconnect your iPhone and try syncing.
4. Enable “Manually Manage Music and Videos”
If automatic syncing isn’t working, you can manually transfer your music to your iPhone.
- Open iTunes and connect your iPhone.
- Click the Device icon at the top left.
- Under Summary, scroll to Options.
- Check Manually manage music and videos.
- Click Apply.
Now, you can drag and drop songs or playlists directly from your iTunes library to your iPhone’s Music section.
5. Reauthorize Your Computer in iTunes
If your computer isn’t authorized with your Apple ID, iTunes may not sync purchased music.
- Open iTunes.
- Click Account → Authorizations → Authorize This Computer.
- Sign in with your Apple ID and password.
- Restart iTunes afterward.
You can check your authorization status anytime under Account → View My Account → Computer Authorizations.
6. Check iTunes Sync Settings
Improper sync configuration can cause iTunes to skip certain music files.
- Open iTunes and connect your device.
- Click the Device icon → Music in the sidebar.
- Check Sync Music.
- Choose either:
- Entire music library, or
- Selected playlists, artists, albums, and genres.
- Click Apply at the bottom.
Reconnecting your iPhone and starting a fresh sync should now work correctly.
7. Disable “Sync Only Checked Songs and Videos”
If this option is enabled and some songs aren’t checked, they won’t sync.
- In iTunes, click Edit → Preferences → General.
- Make sure “Sync only checked songs and videos” is unchecked.
- Click OK, reconnect your iPhone, and try syncing again.
8. Reset iTunes Sync History
Corrupted sync data between iTunes and your iPhone can cause syncing failures. You can clear this data and start fresh.
- In iTunes, go to Edit → Preferences → Devices.
- Click Reset Sync History.
- Restart iTunes and try syncing again.
9. Check for Duplicate or Unsupported Music Files
If you’ve imported songs from outside the iTunes Store, some may use unsupported file formats (like .flac or .wma).
- Open iTunes → locate songs that won’t sync.
- Right-click → select Song Info → File to check the format.
- Convert incompatible formats to AAC or MP3 inside iTunes:
- Go to File → Convert → Create AAC Version.
After conversion, try syncing again.
10. Disable Third-Party Security Software
Sometimes, antivirus programs or firewall tools interfere with iTunes’ communication with your iPhone.
- Temporarily disable your antivirus or firewall.
- Reconnect your iPhone to iTunes.
- Try syncing your music again.
If it works, add iTunes and Apple Mobile Device Service to your antivirus’s exception list, then re-enable protection.
11. Reinstall iTunes
If none of the above methods work, reinstalling iTunes can fix corrupted installation files.
Steps (for Microsoft Store version):
- Press Windows + I → Apps → Installed Apps.
- Find iTunes → click Uninstall.
- Also uninstall:
- Apple Mobile Device Support
- Apple Application Support (32-bit and 64-bit)
- Bonjour
- Restart your PC.
- Reinstall iTunes from the Microsoft Store or Apple’s website.
After reinstalling, reconnect your iPhone and check if syncing works normally.
12. Update Windows 11
Keeping your OS up to date ensures compatibility between Windows, iTunes, and Apple devices.
- Press Windows + I → Windows Update.
- Click Check for updates.
- Download and install any available updates.
Once updated, restart your PC and test syncing again.
13. Reset Location and Privacy Settings on iPhone
If your iPhone doesn’t trust your computer properly, resetting these settings can help.
- On your iPhone, go to Settings → General → Transfer or Reset iPhone → Reset.
- Tap Reset Location & Privacy.
- Reconnect your iPhone to your PC and tap Trust This Computer.
Now try syncing again through iTunes.

If iTunes isn’t syncing music on Windows 11, it’s usually due to outdated software, misconfigured sync settings, or corrupted Apple services.
To fix it quickly:
