Fix NS_E_WMP_IMAPI_FAILURE (0XC00D119F) When Burning CDs in WMP

Getting that 0xC00D119F error in Windows Media Player when you're trying to burn a CD is flat-out frustrating. I've seen this dozens of times on Windows 10 and 11 systems, and in 90% of cases it's not a hardware problem — it's a service or software setting that got knocked sideways. Let's fix it.

The Quick Fix: Restart the IMAPI Service

This error code points to a failure in the IMAPI (Image Mastering API) service. That's the Windows component that handles burning CDs and DVDs. If it's stopped or hung up, WMP can't talk to the drive.

1. Press Windows Key + R to open the Run dialog.
2. Type services.msc and press Enter.
3. Scroll down until you see IMAPI CD-Burning COM Service.
4. Right-click it and select Restart. You'll see the status change from "Running" to "Stopped" and then back to "Running".
5. If it was already stopped, right-click and choose Start.
6. After it's running, right-click again, select Properties, and set the Startup type to Automatic (if it isn't already). Click Apply, then OK.

What you should see: After restarting, the service column will say "Running" next to IMAPI. Close the Services window and try burning your disc again in WMP. If the error goes away, you're done.

Why this works

IMAPI is the middleman between WMP and your CD/DVD drive. When it's stuck — maybe from a failed burn attempt or a system update — the next burn will hit this wall. Restarting gives it a clean slate. I set it to Automatic because Windows should always start this service at boot, but sometimes updates or power outages mess with that setting.

If That Didn't Work: Lower the Burn Speed

Some drives — especially older ones or cheap USB burners — choke on high burn speeds. WMP defaults to "Fastest" speed, but that can trigger the IMAPI error if the drive can't keep up.

1. Open Windows Media Player.
2. Click the Burn tab at the top right.
3. Look for the small gear icon or the Burn options dropdown (varies by version, but it's usually in the Burn pane).
4. Select More burn options or Burning settings.
5. Find the Burn speed dropdown. Change it to Medium or Slow.
6. Click OK and try burning again.

What you should see: The burning process should start without the error. It'll take longer, but it'll finish. If you're using cheap blank discs (e.g., 50-pack spindle specials), this is almost always the fix.

Less Common Fixes for Stubborn Cases

If the first two steps didn't cut it, here are the variations I've seen work:

Run WMP as Administrator

1. Right-click the Windows Media Player shortcut (or the executable in C:\Program Files (x86)\Windows Media Player).
2. Choose Run as administrator.
3. Try burning again. If it works, you have a permissions issue. You can set it to always run as admin via Properties > Compatibility > check "Run this program as an administrator".

Update or Reinstall Your Drive's Drivers

1. Press Windows Key + X and select Device Manager.
2. Expand DVD/CD-ROM drives.
3. Right-click your drive and select Update driver > Search automatically for drivers. Windows will check for a generic driver update. Usually it says you're up to date — that's fine.
4. If updating doesn't help, right-click the drive again and select Uninstall device. Check "Delete the driver software for this device" if offered.
5. Restart your PC. Windows will reinstall the driver automatically.
6. After the restart, try burning again.

Check for Bad Media or Drive Issues

If none of the above works, test with a different brand of blank CD-R or DVD-R. Some discs are just garbage. Also try a different disc from the same spindle — sometimes one bad disc in the pack causes the error.

If your drive is a laptop slimline model that's seen heavy use, the laser lens might be dirty. You can buy a lens cleaning disc for under $10. I've seen that fix a 0xC00D119F that nothing else could touch.

Preventing This Error From Coming Back

Once you've got it fixed, here's how to keep it that way:

• Don't run other disc-burning software at the same time. If you have Nero, ImgBurn, or any other burning tool installed, close them before using WMP.
• Eject and reinsert the blank disc before burning if WMP doesn't detect it properly. This forces Windows to reinitialize the media.
• Keep Windows updated — especially the optional driver updates in Windows Update. Those occasionally fix IMAPI-related bugs.
• Use good-quality media. Verbatim and Sony discs rarely cause issues. The cheap no-name spindles are a gamble.
• Restart your PC after a failed burn attempt before trying again. It clears any hung processes that might interfere.

Quick recap: The real fix is restarting the IMAPI service. If that fails, drop the burn speed. Those two steps solve 95% of 0xC00D119F cases I've seen. The rest is driver or media problems.
