I did the other steps as well, and my performance still seems about the same as when I originally posted. Booting up windows seems to take longer actually.
Sorry but I am confused as you said in your reply #12
I did all of the steps you listed. After doing the second step my computer actually started up and was not sluggish.

Running TFC and disabling unnecessary programs linked to start up will not slow down your system.
Are you again using the notebook with the AC adapter and battery both connected.
Have you installed any new software.
