I made my first Vista disc 2 months ago and everything went fine with the pack I used that has all updates after Sp1. I decided to update with the same pack that had all the new fixes for the last 2 months. Now when importing the whole folder of fixes some of them come up as yellow and match the one's already on the disk,is it best to not reapply these fixes and delete them and just keep the new one's,or add them again?
