<hr>What should I do?<hr>Allow Windows to use the CD as necessary during the file check process.
<hr>Are you saying that the files installed with service packs are not the correct ones and need to be replaced with the originals?<hr>No, definitely not. Service packs contain updates to the system, and are the latest version - and should not be replaced.
<hr>haven't some of the files on the original CD been superceded by files from later service packs and Windows Updates?<hr>Yes - some have, and some haven't. There are a lot of different pieces that make up the whole, and updates and service packs address very specific components of the overall system. Not every file that makes up Windows is replaced with a service pack/hotfix, just the affected ones - just like your car gets repairs to fix failing components, or is taken in for recall service to prevent them.
<hr>wouldn't the SFC undo these updates by replacing later versions of the files with the originals on the CD?<hr>No, because a service pack/hotfix properly registers the updated file version that it replaces with Windows. This is part of the previous answer to your other question...Service Pack and Hotfix files cache the correct version and pull them from there. All of these parts work together: service packs/hotfixes, the WIndows Installer, and Windows File Protection, and a few other things.
Hope that clears it up a little more....but if not, post back. <img src=/S/smile.gif border=0 alt=smile width=15 height=15>
