Windows 8 uses a new version of WinPE. Apparently the Winpe4.0 does not support 16-bit color depth anymore. So to change resolution you have to add the following to your unattend.xml:

SCUP 2011 installs its database in a user folder during installation. As a result another user cannot use SCUP. I’ve got a bit of information on MMS 2012 how to bypass the behaviour:
1. Stop SCUP.
2. Copy scupdb.sdf from “%userprofile%\AppData\Local\Microsoft\System Center Updates Publisher 2011\5.00.1727.0000” to a folder of your choice, for example “d:\System Center Updates Publisher 2011\5.00.1727.0000”
3. Edit Scup2011.exe.config file in SCUP installation folder to modify the following in the Application Settings key (the key is already there, but empty):
<setting name="SSCEDataFile" serializeAs="String">
4. Start SCUP; it should be accessible for multiple users now (with proper permissions of course).
