Introduction
This paper will discuss the Process Explorer utility. According to the assignment information provided in the Unit 5 programming assignment, the Process Explorer v16.2 shows you information about which handles and DLLs processes have opened or loaded. The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the …show more content…
Click on the System Information button (Ctrl+I) to see details of memory usage activity in your system. Provide information about the usage of physical memory, kernel memory and paging in your system. Now start a new program, e.g. Microsoft Excel. Describe how this usage pattern changes when you start this program, a minute after you have started this program, and when you terminate this program. Provide an explanation for this usage pattern.
1. Provide screen shot of resulting page after running the Process Explorer utility

Comment of your paging and list or highlight on screen shot
Paging is zeroed at 51,148, Modified at 46,656 and Standby at 850,820
5. Describe how this usage pattern changes when you start the program, a minute after you have started this program, and when you terminate this program
• I started Skype and as you can see a big uptick in CPU usage at the start of the program.
• One minute after running Skype and CPU is back to normal
• At termination CPU takes a dip
• About one minute after termination the CPU is back to normal usage.
Conclusion
Viewing the CPU usage and memory usage was interesting in that it provided insight into how the memory handles and is affected by new programs and memory requests. Specifically when I took a screen shot of the CPU usage when I started Skype, there was a big uptick in CPU usage and what was even more interesting was the unexpected dip upon termination, even lower than normal usage. The Process Explorer make it useful for tracking the way applications such as Skype work with CPU usage and memory
