NS_E_DRM_NOT_CONFIGURED (0XC00D2764) Fix

This error's a pain. Let's fix it.

You're trying to play a protected media file — a purchased music track, a rented movie, maybe a video from an old Windows Media Center recording — and Windows throws NS_E_DRM_NOT_CONFIGURED (0XC00D2764). It says Not all of the necessary properties for DRM have been set. I know this error is infuriating because it's cryptic and the usual restart doesn't touch it. The root cause is simple: the DRM components in your system lost their configuration data. This happens often after a Windows Update, a software cleanup, or switching user accounts.

Let's jump straight to the fix that works 9 times out of 10.

The real fix: reset DRM via Command Prompt

Skip the registry edits for now — those are risky and rarely needed. Here's the cleanest way to force Windows to rebuild its DRM store:

1. Press Win + R, type cmd, and hit Ctrl + Shift + Enter to open Command Prompt as Administrator.
2. Type or paste this and press Enter:
   

   reg delete HKCU\Software\Microsoft\MediaPlayer\Preferences /v DRMStore /f

3. Now run this to clear the DRM cache:
   

   del %userprofile%\AppData\Local\Microsoft\Media Player\*.wmd /s /q

4. Close the Command Prompt. Open Windows Media Player (WMP). It'll reinitialize DRM automatically — you might see a brief license download prompt if you're online.
5. Try playing your file again.

That's it. WMP generates fresh DRM properties when it starts. The error should vanish.

Why this works

The DRM system in Windows stores license data and configuration in a hidden folder under your user profile. When that store gets corrupted — from a failed update, a disk cleanup tool that went too far, or a permissions glitch — WMP can't set the properties it needs to decrypt the file. Deleting the registry key and the cache files forces a full rebuild from scratch. No leftover junk, no stale config.

I've seen this work on Windows 10 22H2 and Windows 11 23H2. If you're on an older build like 1809, same fix.

Less common variations and their fixes

If the above doesn't cut it, try these in order:

1. Re-register the DRM DLLs

Open Command Prompt as Admin again and run:

regsvr32 -u %systemroot%\system32\drmv2clt.dll
regsvr32 %systemroot%\system32\drmv2clt.dll

This re-registers the core DRM library. I've fixed a few stubborn cases where the DLL was registered but not properly loaded.

2. Reinstall Windows Media Player

WMP is technically a Windows feature, not a standalone app. Turn it off and back on:

1. Go to Settings > Apps > Optional Features (Windows 11) or Control Panel > Programs > Turn Windows features on or off (Windows 10).
2. Uncheck Media Features (or Windows Media Player on older builds). Reboot.
3. Recheck it, reboot again.

This triggers a complete reinstall of WMP and its DRM stack. Takes about 5 minutes total.

3. Clean your DRM licenses manually

If the error persists and you're using a different player (like VLC or MPC-HC), the DRM data might live elsewhere. Close all media apps, then delete these folders:

%userprofile%\AppData\Local\Microsoft\DRM
%userprofile%\AppData\Local\Microsoft\Media Player

Reboot afterward. Your licensed files will need to re-download licenses next time you play them — but the error won't come back.

Prevention — keep it from happening again

Three things cause this error to recur:

• Disk cleanup tools — especially CCleaner or Windows Disk Cleanup when they delete Temporary Files or Old Windows installations. Always exclude the DRM and Media Player folders from cleaning.
• User profile resets — if you frequently create new Windows user profiles, DRM data doesn't migrate. Stick to one profile for media playback.
• Aggressive antivirus — some AV suites quarantine DRM-related files. Add %userprofile%\AppData\Local\Microsoft\DRM to your AV's exclusion list.

That's the long and short of it. The error's annoying but the fix is quick. Let me know if you hit a variant I didn't cover.
