Windows-7 64-bit faulty registry key RRS feed

  • General discussion

  • The following registry entry in Windows 7 RC 64-bit is incorrect:

    HKEY_CLASSES_ROOT\AudioCD\shell\play\command should be:

    "%ProgramFiles%\Windows Media Player \wmplayer.exe" /prefetch:3 /device:AudioCD "%L"

    rather than:

    "%ProgramFiles(x86)%\Windows Media Player \wmplayer.exe" /prefetch:3 /device:AudioCD "%L"

    i.e. remove (x86) from the string.

    With this correction the metafilename "~AudioCD~play" selects the AudioCD session of a CD-Extra (multisession CD) as it should, as it did in prior versions of Windows (Vista 32 and 64, XP, W2K, WME, W98).  The key is correct in Windows-7 32-bit.

    With the existing incorrect key the command fails.

    See related thread for additional details.


    Please correct this faulty entry before the final release.

  • I withdraw my suggested registry change to Win7-64!  It's fine as it is:

    HKEY_CLASSES_ROOT\AudioCD\shell\play\command = "%ProgramFiles(x86)%\Windows Media Player \wmplayer.exe" /prefetch:3 /device:AudioCD "%L"

    What is surprising is that the application which selected the CD-Audio session in Vista-64 and XP-64 acts differently in W7-64. 

    A change to the application has been made which accommodates all versions of Windows from Win7-64 all the way back to Win95.
