Final ESU Updates for Windows 7 SP1 (Retired!) in User Contributed Update Lists Posted June 9, 2015 I am not sure if anyone can help, but I created a slipstreamed ISO with the updates to use with Deployment Workbench. During the install it crashed out with this error:"Windows could not parse or process unattended answer file [C:\Windows\Panther\unattend.xml] for pass [specialize]. A component or setting specified in the answer file does not exist." Does anyone know if its possible to fix this and use a slipstreamed ISO with deployment workbench?
