NS_E_WMP_INVALID_MIN_VAL (0XC00D100A) fix for slider errors

What this error means

You're playing a video or audio file in Windows Media Player 12 (on Windows 7, 8, or 10) and you get a popup with error code 0XC00D100A. The message says: The Min property cannot be greater than Max property. This usually happens when a slider control — like volume, seek position, or a custom UI element — has its minimum value set higher than its maximum value. Think of it like a ruler where the 1-inch mark is past the 12-inch mark. Doesn't make sense, right?

I've seen this most often when someone tries to play a video file with a corrupted codec or after installing a media player plugin that messes up the interface. Sometimes it's just a glitch from a bad playlist file. The fix is usually quick — start with the simplest step.

Fix 1: Clear the current playlist and restart WMP (30 seconds)

This handles cases where a corrupted playlist entry is causing the Min/Max mismatch. The problem might be that the file you're trying to play has a bad header that confuses WMP's slider position.

1. Close Windows Media Player completely. Don't just minimize it — right-click the taskbar icon and choose Close window. Or press Alt+F4.
2. Open File Explorer. Press Win+E on your keyboard.
3. Go to your Music or Videos folder — wherever that problem file is stored.
4. Delete the file that triggered the error (or move it to a different folder). If you're not sure which file it was, skip this step.
5. Press Win+R to open the Run dialog. Type %userprofile%\AppData\Local\Microsoft\Media Player and hit Enter. This opens the folder where WMP stores its playlist cache and settings.
6. Delete everything inside that folder. Don't worry — WMP will recreate these files when you start it again. You might need to give permission if Windows asks.
7. Press Win+R again, type wmplayer.exe /prefetch:1, and hit Enter. This starts WMP with a clean slate. Watch for the error — if it's gone, you're done.

What to expect: After deleting the cache, WMP will take a few seconds longer to start the first time. It'll rebuild your library from scratch. Your playlists and ratings will be gone, but the error should stop.

Fix 2: Reset WMP settings using the registry (5 minutes)

If Fix 1 didn't work, the problem is likely in WMP's stored settings — maybe a corrupted slider position value in the registry. This fix nukes those settings without affecting your media files.

1. Close Windows Media Player again if it's open.
2. Press Win+R, type regedit, and press Enter. Click Yes if UAC asks.
3. Go to this key: HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Player\Settings
4. Look on the right side for any value named Volume, Balance, Rate, or SeekPosition. These are the slider settings. Right-click each one and choose Delete. Confirm if asked.
5. Now navigate to this key: HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences
6. Delete the entire Preferences key. Right-click the Preferences folder and choose Delete. Again, WMP will recreate it later.
7. Close Registry Editor.
8. Start WMP again (press Win+R, type wmplayer.exe). You'll see the setup wizard for choosing music folders. Accept defaults or set your own. Then try playing the same file that caused the error.

Important: If you're not comfortable editing the registry, skip this fix and go to Fix 3. Deleting the wrong key can mess up other apps. But if you follow the path exactly, it's safe.

Fix 3: Disable or remove conflicting codecs/plugins (15+ minutes)

This error sometimes comes from third-party decoders (like K-Lite Codec Pack, CCCP, or Shark007) that install their own slider controls. They override WMP's default behavior and can cause the Min/Max inversion. I've seen this a lot with old video files encoded in formats like DivX 3 or XVid that trigger a custom slider plugin.

1. Check which codecs you have installed. Press Win+R, type mmsys.cpl, and press Enter. Go to the Playback tab, right-click your default speakers, choose Properties. Go to the Advanced tab and look at the list of installed decoders. Actually, that won't show you everything. Instead, do this:
2. Press Win+R, type control, and press Enter. Go to Programs and Features (in Windows 10/11) or Uninstall a program.
3. Look for any codec packs or media player plugins in the list: K-Lite, CCCP, DivX, Xvid, ffdshow, LAV Filters, madVR, ReClock, AC3Filter, Haali Media Splitter. Right-click each one and choose Uninstall.
4. Restart your computer after uninstalling. Don't skip this — some codecs leave lingering registry entries that need a reboot to clear.
5. Test WMP again. If the error goes away, you've found the culprit. Reinstall codec packs one at a time, testing each, until you find the one that causes the error. Then either skip that pack or use a different version.

Alternative if you don't want to uninstall everything: Try disabling the codec's slider integration. For LAV Filters, open its configuration (from Start menu), go to the Stream Switcher tab, and uncheck Use system default for slider controls. For ffdshow, open its video decoder config, go to Overlay, and uncheck Enable slider support.

When nothing else works

If you've done all three fixes and the error still shows, the problem might be a corrupted Windows Media Player installation itself. On Windows 10, you can repair it through Settings > Apps > Apps & features > find Windows Media Player, click Advanced options, and choose Repair. On Windows 7, you'll need to turn it off and back on through Control Panel > Programs and Features > Turn Windows features on or off. Uncheck Media Features, restart, then re-check it.

One last thing — some badly encoded files are just broken. They have seek tables that point to impossible positions. In that case, the file itself is toast. Convert it using HandBrake or VLC's export function. But try the fixes above first — nine times out of ten, it's a simple settings glitch.
