Fix NS_E_WMP_HME_NOTSEARCHABLEFORITEMS (0XC00D0FC1)

Yeah, that error's a pain—you just want to play a file, and Windows Media Player throws up that cryptic container nonsense. Let's fix it fast.

The Fix: Reset the Media Library

The quickest way to kill this error is to force WMP to rebuild its library database. Don't worry, you won't lose your actual files, just the WMP index.

1. Close Windows Media Player completely.
2. Press Windows + R, type %LOCALAPPDATA%\Microsoft\Media Player, and hit Enter.
3. Delete everything in that folder. Yes, all of it. You might see a folder named Media Player — go inside and delete the contents there too.
4. Restart your PC (or just relaunch WMP).
5. When WMP opens, it'll re-scan your default libraries (Music, Videos, Pictures). This can take a few minutes if you have a large collection.

That's usually it. The error comes from a corrupt library entry—a file that WMP indexed but can't actually read anymore (because it was moved, deleted, or is on a disconnected drive). Clearing the library forces a fresh start.

Why This Works

The error NS_E_WMP_HME_NOTSEARCHABLEFORITEMS literally means Windows Media Player's Home Media Engine can't perform a search on a container—that's a library grouping like "All Music" or "Recently Added." When a database entry points to a file that's gone or unreadable, the search fails and you get this error. Deleting the library files wipes that bad reference. WMP rebuilds from scratch, and the error disappears.

Had a client last month whose entire print queue died because of something similar—their media server had stale entries pointing to a NAS that was off. Reset the library, problem gone.

Less Common Variations

If resetting the library didn't work, the issue might be deeper. Here are other culprits I've seen:

1. Corrupted DRM licenses

If the error happens specifically with purchased or rented content, your DRM licenses could be corrupted. Reset them:

1. Close WMP.
2. Open %PROGRAMDATA%\Microsoft\Windows\DRM (you'll need admin rights).
3. Rename the DRM folder to DRM_old.
4. Restart WMP—it will recreate the folder and re-download licenses next time you play protected content.

2. Network library issue

If your WMP library includes folders from a network share or homegroup, the share might be temporarily unreachable. Go to Tools > Options > Library and remove any network folders, then re-add them after confirming the share is online.

3. Third-party codec packs

Some codec packs (like K-Lite) can mess with WMP's metadata reading. Try uninstalling any codec packs temporarily—if the error stops, update the codec pack or use a different one.

Prevention: Stop It From Coming Back

Now that it's fixed, here's how to avoid re-triggering it:

• Don't delete or move files while WMP is running. WMP indexes files in real-time; if you yank a file out from under it, it leaves a stale entry.
• Use WMP's built-in folder monitoring. When you add or remove music, let WMP do it via Library > Add to Library—that way it updates cleanly.
• Keep external drives connected if they're in your library. If you must unplug, eject them properly and remove the folder from WMP first.
• Run a disk check periodically if you see frequent library errors—bad sectors can corrupt the library database.

That's the whole battle. Nine times out of ten, the library reset kills it. If you're still stuck after trying the variations, you might be dealing with a deeper Windows corruption—but that's rare. Most people fix this in under five minutes.
