NS_E_WMPCORE_PLAYLIST_NO_EVENT_NAME (0XC00D10A5) Fix

Windows Errors Beginner 👁 1 views 📅 May 29, 2026

Windows Media Player hits this when a playlist file is missing its name tag. Corrupted .wpl or .zpl files are the usual cause. Here's how to fix it.

Cause #1: Corrupted or Incomplete Playlist File

This is the most common reason you're seeing error 0XC00D10A5. The playlist file itself — usually a .wpl (Windows Playlist) or .zpl (Zune playlist) — has a missing or corrupted <title> tag inside. Without that tag, Windows Media Player can't display a name for the playlist, and it throws the NS_E_WMPCORE_PLAYLIST_NO_EVENT_NAME error.

This often happens when a playlist was created by an older program or got cut off during a file transfer. For example, you might drag a .wpl file from a network drive and the copy operation fails silently. Or maybe a third-party music manager wrote the file without the name element.

How to Fix It

  1. Open Windows Media Player. Don't close it yet.
  2. Right-click on the playlist that shows the error in the left pane. Choose Delete.
  3. A dialog pops up asking "Remove from library only" or "Delete from library and computer." Pick Remove from library only.
  4. Expected outcome: The playlist disappears from the left pane. The error should stop immediately. If it doesn't, move to the next step.

Now, if you actually want that playlist back — maybe it had music you liked — you can recover it by rebuilding the file manually.

  1. Locate the original .wpl file on your hard drive. They're usually in %USERPROFILE%\Music\Playlists or %USERPROFILE%\Music\Zune\Playlists.
  2. Right-click the file and open it with Notepad.
  3. Look for the line near the top that says <title>. If it's missing, add this right after the <smil> tag:
<head>
  <title>My Playlist</title>
</head>

Replace My Playlist with whatever name you want. Save the file.

  1. In Windows Media Player, press F3 to refresh the library. Expected outcome: The playlist should now appear properly named and the error should be gone.

Cause #2: Stale or Corrupted Library Cache

Sometimes the playlist file itself is fine, but the database that Windows Media Player uses to catalog your media gets corrupted. This is especially common after a Windows Update or a major software change. The player reads a cached version of the playlist metadata that's incomplete — missing the name field — even though the actual file has it.

You'll notice this if you delete the playlist (per Cause #1) and the error goes away temporarily, but comes back after a restart. That's a dead giveaway the cache is the problem.

How to Fix It

  1. Close Windows Media Player completely. Check Task Manager to be sure.
  2. Press Windows Key + R, type %LOCALAPPDATA%\Microsoft\Media Player, and hit Enter.
  3. You'll see a folder with a bunch of files like CurrentDatabase_372.wmdb or similar. Don't panic — this is the library cache.
  4. Select everything in that folder. Right-click and choose Delete. You'll get a permission warning about some files; just click Yes or Continue.
  5. Expected outcome: The folder empties. Windows will rebuild these files when you open WMP again.

Now open Windows Media Player again. It'll take a minute to scan your Music folder and rebuild the library. Wait for it to finish — you'll see a progress bar. Once it's done, your playlists should load without the error.

Real-world tip: One of my users kept hitting this error every few weeks. Turned out a backup tool was restoring old cached files into that folder. We excluded %LOCALAPPDATA%\Microsoft\Media Player from the backup schedule. Problem never came back.

Cause #3: File Ownership or Permission Issue

This one's rarer, but I've seen it happen after migrating user profiles from an old PC to a new one. The playlist file sits on a drive where your current user doesn't have full read/write access. Windows Media Player can't read the metadata properly, so it sees a blank name field.

You'll typically see this only for playlists stored in a non-standard location — like on an external drive or a network share. If the error only happens with playlists from one specific folder, permissions are worth checking.

How to Fix It

  1. Find the playlist file that triggers the error. Right-click it and choose Properties.
  2. Go to the Security tab. Click your username in the Group or user names list.
  3. Under Permissions, make sure Read & execute and Read are checked. If they're greyed out or missing, you'll need to take ownership.
  4. Click Advanced at the bottom. Next to Owner, click Change.
  5. Type your username (or Everyone if you want quick fix) and click Check Names. It should underline it. Click OK.
  6. Check the box Replace owner on subcontainers and objects if it's a folder. Click Apply, then OK.
  7. Expected outcome: You now own the file. Go back to the Properties > Security tab, click Edit, and give yourself full control if you want. Click Apply.

Now reopen Windows Media Player and test the playlist. The error should be gone.
