My machine was running like a dog (Woof! Woof!) So going into the task manager to see what was going on, CPU utilization was 100% and there were 16 instances of TCC (and of, course, conhost) running. The problem is that I only had 4 active TCC sessions going (three in one Take Command session, another one in a different Take Command session, and a single instance in a third Take Command session that was running Administratively). So I used SystemInternal's pskill command to kill all instances of TCC (and their associated Take Commands and conhosts also died) and my system is actually useable again (why I'm even able to type this posting). Now I will be the first to admit that Task Manager showed that collectively they were using less than 10% of the CPU, but killing them all fixed the problem, and 10% was strange because after killing them all total CPU utilization went down to about 60%. What is going on here?
