NS_E_DRM_SDMI_TRIGGER (0XC00D2755): Fix This DRM Transfer Error Fast

The short version

You're trying to copy a DRM-protected media file (usually WMA or WMV from an old Napster, Zune, Rhapsody, or PlaysForSure store) to a device — phone, MP3 player, SD card, whatever — and Windows Media Player throws NS_E_DRM_SDMI_TRIGGER (0XC00D2755). What it actually means: the DRM package on the file requires a newer WMP Security Upgrade than the one installed, or the license is tied to a feature your current player doesn't support.

Nine times out of ten, the machine trying to do the transfer is running an ancient WMP 9, 10, or a stripped-down N or KN edition of Windows with the Media Feature Pack missing. Upgrade WMP first. That's the fix that actually works.

Cause 1: Old Windows Media Player (the most common one)

This is the headline. The SDMI_TRIGGER error literally fires when the file demands a Security Upgrade that your WMP doesn't have. If you're on WMP 9 or 10 — which was the default on XP and Server 2003 — you're going to hit this every time. Real-world trigger: someone digs out a 2006-era Zune or Creative Zen, plugs it into a Windows 7 or 8 box that's never been updated, and tries to sync a WMA from an old subscription service.

Fix: upgrade to WMP 12

1. Download Windows Media Player 12 from Microsoft's site (or run Windows Update — it'll offer it as an optional component on Win7/8/8.1).
2. Install it. Reboot even though it probably won't ask.
3. Open WMP, go to Help > About Windows Media Player and confirm you're on 12.x.
4. Try the transfer again.

On Windows 10 and 11 you already have WMP 12, so if you're still seeing 0XC00D2755 there, jump to Cause 2 — you've got a different problem.

For Windows N and KN editions (common in the EU and Korea), the Media Feature Pack is missing. Install it:

DISM /Online /Add-Capability /CapabilityName:Media.MediaFeaturePack~~~~0.0.1.0

Then reboot. Without that pack, WMP can't handle the DRM pipeline at all.

Cause 2: Corrupted or missing DRM license store

WMP keeps its DRM licenses in a hidden folder. If that store gets corrupted — usually after a botched Windows Update, a user profile migration, or someone running a "cleaner" tool that nuked hidden folders — every DRM operation fails, including transfers. You'll see 0XC00D2755 even on WMP 12.

Fix: reset the DRM store

1. Close WMP completely. Check Task Manager — the wmplayer.exe process sometimes hangs around.
2. Open File Explorer, enable hidden files, and browse to:
   C:\Users\<YourName>\AppData\Local\Microsoft\DRM
3. Rename the DRM folder to DRM.old. Don't delete it — you might want it back.
4. Also check C:\ProgramData\Microsoft\Windows\DRM and rename that one too if it exists.
5. Relaunch WMP. It rebuilds the DRM folder on first startup.
6. Re-download the license for the file. You'll need to sign into the original store or reacquire the DRM-protected content.

Heads up: resetting the DRM store wipes every existing license on that machine. If you've got other DRM content you haven't transferred yet, do those transfers before you nuke the store.

Cause 3: The file's DRM is too old to authorize on a modern device

Some DRM schemes — especially early PlaysForSure and Janus DRM from subscription services that shut down years ago — simply can't be re-authorized. The license server is gone. Yahoo Music, MTV Urge, early Napster To Go, Virgin Digital — all dead. When you plug in a modern device, WMP tries to check the license against the file's transfer rules, can't reach the server, and throws SDMI_TRIGGER.

Fix: strip the DRM (legally, where permitted)

If you legally purchased the content and the server's gone, you're in a gray zone. In the US, the Librarian of Congress has repeatedly granted exemptions for format-shifting DRM-protected media you own. Practically speaking:

• Option A: Use FairUse4WM on an old VM (XP or 7 32-bit). It still works on DRM v1 and v2 files. Won't touch v7+.
• Option B: Play the file back on the original licensed machine and capture it with Audacity (WASAPI loopback) or a HDMI capture card. Ugly but works.
• Option C: Re-buy the content from a modern store (Amazon, iTunes, Bandcamp). Honestly faster for most people.

Don't bother with generic "DRM remover" freeware from download sites. Half of it is malware, and none of it handles SDMI-era Janus DRM properly.

Note: SDMI (Secure Digital Music Initiative) is a dead standard from 1999. Any file still tagged with it is at minimum 20 years old. Treat it like an artifact — extract what you can, then let it go.

Quick-reference summary

What I'd actually do

Check WMP version first. It takes 10 seconds and rules out the most common cause. If you're on 12 already, reset the DRM store — that's the second most common fix and it's reversible. If neither works, the file's DRM is dead and no amount of Windows fiddling will revive it. Move on.
