I got WMP9 to install unattended right. The problem is I need to get rid of that setup screen that appears after you first run it. That screen appears for every new user that runs WMP, is there a way to have it not appear and just run WMP with defaults?

With a registry file tweak

Windows Registry Editor Version 5.00

; Windows Media Player 1st Run Disable
; ====================================
[HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences]
"AcceptedPrivacyStatement"=dword:00000001
"FirstRun"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsMediaPlayer]
"GroupPrivacyAcceptance"=dword:00000001

That was such a big help, thanks

Personnally, I just use this :

;Disable find assistant
[HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences]
"LibraryHasBeenRun"=dword:00000001
;Disable setup assistant
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsMediaPlayer]
"GroupPrivacyAcceptance"=dword:00000001
