The default behavior of Windows Media Player is to process HTML scripts that are contained in Windows Media files.
After applying MS02-032: Windows Media Player Rollup Available, you can disable this ability:
1. Copy /Paste the following to a PlayerScriptCommandsDisabled.reg file:
Windows Registry Editor Version 5.00
\[HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences\]
"PlayerScriptCommandsEnabled"=dword:00000000
2. Merge the PlayerScriptCommandsDisabled.reg file with your registry.
To re-enable HTML script processing:
1. Copy /Paste the following to a PlayerScriptCommandsEnabled.reg file:
Windows Registry Editor Version 5.00
\[HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences\]
"PlayerScriptCommandsEnabled"=dword:00000001
2. Merge the PlayerScriptCommandsEnabled.reg file with your registry.
NOTE: If the PlayerScriptCommandsEnabled Value Name is missing from the HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences key, script processing is enabled.
