Another trick I found a while ago is to clear out the prefetch folder. c:\windows\prefetch

This folder contains a copy of all the applications that windows prefetches at boot time to speed up your application start time. Problem is that over time a lot of excess stuff accumulates in there. Clear it out, your next boot will be longer but then reboot and see what happens.

When its running slow just after booting, run Task manager, and look at what process is registering a high CPU usage.
If svchost and wuauclt are there and high, just google
"svchost wuauclt 100 cpu"
Windows reintroduced old bugs in windows updates recently that can kill the cpu, esp if you only have one core.
I had this problem about 4 weeks ago and had to manually install one of the patches to cure it. Its a well known bug and recently fixed, but until the fix is loaded, it can kill your startup.
