Performance

As well as debugging and virus checks, another indicator on the performance of a computer system will be as simple as the number of background systems running at the time. This is seen by viewing the task manager and going under processes, this will reveal all of the systems running in the background of the computer. The more (or bigger) of these systems running, the lower the performance of the computer, as it is taking more of its processor to cope with this additional activity.

This particular system has a few unnecessary programs running in the background which may be slowing down the PC. Things like Light Scribe  Hamachi, and Chrome will slow down the computer because you are not using them, but they still run invisibly.
