What is the proper way of debugging a slow Windows installation?
I've been running Windows 7 on my laptop for about a year now, and have had no issues regarding speed. About a month ago, my computer had what I refer to now as an "episode" where it runs extremely slow, when I open Task Manager I see no significant processes running, nothing out of the ordinary, but my computer is at 100% CPU usage.
Usually restarting fixed this problem, but it seems to have gotten worse to the point where restarting does not fix this problem, and it's interfering with my work.
What should I do?

is the culprit, in which case you’ll need to use ProcExp to figure out which service is the problem.
