Having winlogon using a LOT of CPU at bootup time is quite normal. Best way to fix this is to uninstall a lot of programs, or clean up all the crap it's trying to sort through. However, even the most greviously configured machine shouldn't run the winlogon at full CPU for more than a minute or two. So if this is NORMAL behaviour, you most likely have a virus or some malware.
