Firefox: Remove "Microsoft DRM" from your plugins

Following up on the Adobe Acrobat post about removing unwanted plugins from Firefox I spotted another that I've left disabled for some time, "Microsoft DRM".

DRM is a plague causing more grief than good to consumers. It also serves as a method to restrict content to countries, even though it's the world-wide web and I have no interest in keeping this shit on my computer.

Normally I wouldn't post this up because at least this DRM plugin stayed disabled in Firefox, however I'm posting it because it's a bit trickier to get rid of.

If you delete "npdrmv2.dll" and "npwmsdrm.dll" from "C:\Program Files\Windows Media Player", it'll automatically restore it from "C:\WINDOWS\system32\dllcache".

This is because it's been embedded deep into the Windows operating system and protected by "Windows File Protection".

  • Copy the contents below into "removeDRM.bat" and save it onto your desktop.

del C:\Windows\System32\dllcache\npdrmv2.dll
del C:\Windows\System32\dllcache\npwmsdrm.dll
del "C:\Program Files\Windows Media Player\npdrmv2.dll"
del "C:\Program Files\Windows Media Player\npwmsdrm.dll"

  • Restart your computer into safe mode.
  • Double click "removeDRM.bat"
  • Restart your computer back into normal mode

That should be it! You can quickly check to see if the files are back, but they shouldn't be.

Yeah that's right, get out and STAY out!
