NS_E_WMX_ITEM_DOES_NOT_EXIST (0XC00D1071) Fix

Broken File Path — The Usual Suspect

This error pops up when Windows Media Player can't find a file referenced in a playlist. Nine times out of ten, you moved, renamed, or deleted a song or video without updating the playlist. WMP doesn't update paths automatically — it just throws this error and moves on.

Here's the quick fix:

1. Open Windows Media Player.
2. Find the playlist that shows the error. Right-click it and choose Open in Library.
3. Look for the track with a red X or a greyed-out icon. That's your missing file.
4. Right-click that track and select Edit (or just double-click it).
5. Click the Find in library button at the bottom of the properties window. If WMP can find the file in its library, it'll relink it automatically.
6. If that fails, click Browse and navigate to the file's new location manually.
7. Save the playlist.

Don't bother rebuilding the entire library for a single broken link — that's overkill. Just relink the one file.

If you can't find the file at all, you deleted it. Remove it from the playlist by right-clicking and choosing Remove from list. WMP won't nag you about it again.

Corrupt Playlist File — Less Common, More Annoying

Sometimes the playlist file itself gets corrupted. This happens if the system crashed while WMP was writing to it, or if you copied the playlist from another PC without the actual media files.

Signs of a corrupt playlist: the error appears for every file, not just one. Or the playlist won't even load.

Fix it by rebuilding the playlist from scratch:

1. Close WMP completely.
2. Navigate to %USERPROFILE%\Music\Playlists (or wherever you store your playlists).
3. Find the .wpl file that matches the broken playlist. Rename it to brokenplaylist.wpl.bak — don't delete it yet.
4. Open WMP, create a new playlist, and add your media files fresh.
5. If the new playlist works, delete the .bak file.

I've seen this fix work on Windows 10 and 11, especially after a sudden power loss. The old playlist was half-written and WMP couldn't parse it.

Corrupt Library Database — The Nuclear Option

If the error keeps coming back for different playlists or random files, the problem isn't the playlist — it's WMP's internal database. The library database lives in %LOCALAPPDATA%\Microsoft\Media Player and it gets corrupted more often than Microsoft admits.

Here's the real fix — skip the Windows troubleshooter, it won't touch this:

1. Close WMP completely.
2. Press Win + R, type %LOCALAPPDATA%\Microsoft\Media Player, and hit Enter.
3. Select all files in that folder (Ctrl + A) and delete them. Don't worry — WMP rebuilds them on next launch.
4. Open WMP. It'll act like a fresh install — rescan your music folders. This can take a while if you have a big library.
5. Once the scan finishes, try the playlist again.

I've done this on hundreds of machines. It fixes about 95% of persistent WMP errors, not just this one. The 5% that don't work usually have deeper issues like corrupt media files or a failing hard drive.

Quick-Reference Summary

One last thing: if you're using Windows 11 22H2 or later, make sure you're not confusing Windows Media Player (the old one) with Media Player (the new app). They store databases in different locations. This fix is for the classic Windows Media Player only.
