To control whether you allow the Windows Media Player Automatic Update feature, user
the following Windows XP registry hack:
Hive: HKEY_LOCAL_MACHINE
Key: SOFTWARE\Policies\Microsoft\WindowsMediaPlayer
Name: DisableAutoUpdate
Type: REG_DWORD
Value: 1
The same registry hack works for Windows Media Player 7.0 and 7.1 used in NT and
Windows 2000.
For older Windows with Windows Media Player 6.4, the key is
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer\EnableAutoUpgrade, Type=REG_SZ,
and value="No".
