 CPU      Memory        Disk        Network 

The columns are sortable.  Click them to sort/reverse sort by that column.

_____________________________
What is the largest process by CPU usage and how much of the CUP is it using:
_____________________________

Right-click Task Manager in Apps category. Select Properties.
Where is its file ("Location:"):_________________________  Size:________

Start File Explorer. Navigate/browse to  C:\WINDOWS\System32 folder.

What happened:________________


**Details
A unique PID is assigned to each running process by the operating system 
and is how the operating system controls/manages the processes. 
What is the PID of the notepad.exe process:_______
What is the PID of the running Taskmgr.exe itself:____________
Close/terminate TaskManager.  Start it again.  What is its PID now:_______
The PID column is sortable.
What is PID 0:___________________________________
What is the lowest numbered (non-zero) PID __________
 and what is the name of that process:_____________________



**Performance
CPU
Make&model:_______________________________
Instantaneous Utilization:______    Speed:__________   #Processes:_____
#Cores:____  L1 Cache:_____  L2 Cache:______ L3 Cache:______

Memory
How much:__________
In use:__________________________

Disk
Capacity:________


Download the cpuwarm.exe program (link on class web site next to the
link to this file) and run it.  
What does the CPU % Utilization go to:________
In Processes: Terminal was started to run cpuwarm.exe in it as a Background process.
Sort by CPU column, what program is using the most CPU:_____________
While still running that cpuwarm, start it again. Two of them will be running.
  Display both on the desktop.
What does the CPU % Utilization indicate now:_________
In Processes: Each cpuwarm.exe process is using about how much of the CPU:_______
In Processes, pretend cpuwarm is a runaway process that needs to be terminated
 so "End task" it/them.


**Services
Services start many/most of the background processes.
sort by Status.
Notice that each Running service has a PID, meaning each service is running 
as a process or as part of some process.
Too many to count...
Select DNScache   PID:________    
   Right-click, select "Go to details".  Name of process:____________
