NS_E_CD_QUEUEING_DISABLED (0xC00D11FF) Fix

Quick Answer

Open regedit, go to HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences, create a DWORD QueueEnabled, set it to 1. Restart WMP. If you're on a managed PC, check Group Policy.

Why This Happens

This error pops up in Windows Media Player 11 or 12 (Windows 7 through 11) when you try to queue a CD track — usually by right-clicking and selecting “Add to 'Now Playing' List.” The culprit here is almost always a registry value that's either missing or set to 0. Sometimes a group policy from an overzealous IT admin disables it, or a third-party media app (like iTunes or VLC) tweaked the setting during installation. I've seen it happen after a Windows Update too, though that's rarer. The error code 0xC00D11FF means WMP's internal queue system isn't listening — it's not broken, just switched off.

Step-by-Step Fix

1. Close Windows Media Player — make sure it's not running in the background. Check Task Manager if you're not sure.
2. Press Win + R, type regedit, hit Enter. Accept the UAC prompt.
3. Navigate to:

   HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences

   If the Preferences key doesn't exist, right-click MediaPlayer → New → Key → name it Preferences.
4. In the right pane, right-click → New → DWORD (32-bit) Value. Name it QueueEnabled.
5. Double-click QueueEnabled, set Value data to 1, base to Hexadecimal (though Decimal works fine here). Click OK.
6. Close regedit. Open WMP and try queueing a CD track. It should work immediately — no reboot needed.

Alternative Fixes If Regedit Doesn't Help

Group Policy (Windows Pro/Enterprise)

If you're on a managed machine and the registry key reverts to 0 after a reboot, group policy is overriding it. Open gpedit.msc, go to User Configuration → Administrative Templates → Windows Components → Windows Media Player → Playback. Set “Prevent CD track queuing” to Not Configured or Disabled. Then run gpupdate /force from an admin command prompt.

Third-Party WMP Plugins

Some codec packs or plugins (like Shark007 or K-Lite) mess with WMP's queue behavior. Uninstall any media codec packs, reboot, then re-add the registry key above. I'd skip installing codec packs altogether — Windows 10/11 handles most formats natively now.

Prevention Tip

If you regularly import CD tracks and queue them, create a .reg file with this content and run it whenever you reinstall Windows:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences]
"QueueEnabled"=dword:00000001

Save it as enable_cd_queue.reg, double-click to merge. That'll save you digging through regedit again.

One more thing — don't bother with the “Fix it” tools from Microsoft's support site for this error. They rarely help because the root cause is almost always a missing or zeroed registry value. A direct regedit edit is faster and more reliable.
