I have a slip streamed windows install with service pack 3, however when I run windows update, it tells me I need SP3 and a whole bunch of other things. Can anyone with experience with slipstream installing help out?
Delete your source folder and try integrating again. I've done it a few times and it's worked out great. Or if you want, just grab SP3 from WU. It should only install the files you need so if something is missing you'll get just that.
