Keep DRM data?

Post by XIII » Sat Feb 17, 2007 8:51 am

I have been using nLite/RyanVM for quite some time, but now I really hesitate to perform another clean Windows install.

Since I've upgraded WMP to WMP11 I have bought several DRM-protected music tracks. Unlike WMP9/10, WMP11 is not able to backup/restore licenses (this did the trick for a clean install in the past). This means I would loose the licenses for all my bought tracks.

Or is there a way to save the DRM licenses for my PC after all? (I don't dare to try whether just storing everything in "C:\Document and Settings\All users\DRM" will do).

What can I do?

I am not sure that it does:
Microsoft wrote:Note You must contact any third-party stores from which you purchased music to reset the licenses for that music.
This is exactly what I'm trying to prevent, considering the hassle this has been in the past.

I thought maybe this link would be helpful.

I thought that was the link that resets DRM and causes one to contact content providers, but perhaps I should give it a try when I have some spare time (not anytime soon, I'm afraid)

Anyway, there should be some files I have to save before re-installation, because licenses are not stored in the (WMA) audio files themselves I believe.

From what I've found on the net, I would first try backing up:
  • the C:\Documents and Settings\All Users\DRM directory
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DRM
  • HKEY_CURRENT_USER\Software\Microsoft\Windows Media\WMSDK\General
I have no idea whether this works... And hesitate to mess with the working installation...

Did not really have the time, but tried anyway...

Just restoring the things I mentioned does not work at all. In fact, if you click on the link for technical support information in the WMP about box, it does not display any individualization information...

If I first click on the link Ryan posted and then restore the things I mentioned, I do get this individualization information. Unfortunately then the DRM information of my bought files is listed as "This file is missing media usage rights" (after individualization, but before restoration, it displays media usage rights, but states I do not have them).

Any suggestions?

Otherwise I would be stuck to my current installation, or loose my investment in those files. That would suck! :evil:

Actually, after a lot of hard work it turns out to be rather simple:

Backup/restore:
  • all files in c:\Documents and Settings\All Users\DRM
  • registry key KEY_CLASSES_ROOT\CLSID\{3DA165B6-CC41-11d2-BDC6-00C04F79EC6B}
Apparently, that registry key stores the unique identifier of WMP.

So, now I can start experimenting with nLite and Ryan's update pack again :D
