Some device designs require that users are not prompted with the "First Run / OOBE" dialogs in Internet Explorer and Windows Media Player. These are the dialogs that let you set defaults like search provider (IE) or supported media types (Media Player). These can be disabled through the registry using the guidance here:
Windows Media Player - GroupPrivacyAcceptance
Internet Explorer - First Run
If you want to do this directly in ICE, you can use reg.exe and add Synchronous Commands to do the work:
1) Add two Synchronous Commands to your Answer File
a. On the Insert menu, point to Synchronous Command. Choose oobeSystem as the configuration pass.
b. The Create Synchronous Command dialog box opens.
c. In the Enter command line text box, enter :
REG ADD "HKLM\Software\Policies\Microsoft\Internet Explorer\Main" /v DisableFirstRunCustomize /t REG_DWORD /d 1 /f
d. Choose OK.
e. The command is added to the answer file in the selected configuration pass.
f. On the Insert menu, point to Synchronous Command. Choose oobeSystem as the configuration pass.
g. The Create Synchronous Command dialog box opens.
h. In the Enter command line text box, enter :
REG ADD "HKLM\Software\Policies\Microsoft\WindowsMediaPlayer" /v GroupPrivacyAcceptance /t REG_DWORD /d 1 /f
In the Settings pane in ICE notice the two new FirstLogonCommand entries:
Internet Explorer and Windows Media Player will both open, for all users, with the First Run disabled.
Note: These settings are set in HKLM, so they will apply to all users.
