The knowledge base article linked in that old blog post (located at http://support.microsoft.com/?kbid=891664) contains information that is applicable to Windows Vista as well as older versions of Windows, but it does not specifically state that it applies to Windows Vista.

According to this knowledge base article, you can reset DRM by deleting the files in the DRM folder on your system (but make sure to not delete the DRM folder itself because that can cause other problems on your system).

The default location of the DRM folder in Windows Vista is c:\ProgramData\Microsoft\Windows\DRM, but it might not be in the same location on every system. To reliably determine the location of the DRM folder on your system, you can look up the data in one of the following registry values:

For 32-bit versions of Windows Vista:

[HKEY_LOCAL_MACHINE\Software\Microsoft\DRM]
DataPath

For 64-bit versions of Windows Vista:

[HKEY_LOCAL_MACHINE\Software\WOW6432Node\Microsoft\DRM]
DataPath

Note - the DataPath value is in binary format, so you will have to double-click on the DataPath value in regedit.exe and look at the right-hand column of the Edit Binary Value dialog box that appears to see the plain text version of the path.
