Threads with higher priority receive more processor time. Unfortunately, the Task Manager doesn't allow you to view individual threads, much less their priorities you can use the PVIEWER utility, found in the Windows Support tools, to view individual threads. However, each process as a whole also has a priority, and Task Manager lets you view and modify a process' priority. To look at a process' priority, right-click on the process and select the Set Priority command to invoke a submenu that lists priorities.
The process' current priority level is marked with a dot. You can change the priority by selecting one of the six options from the list: real time, high, above normal, normal, below normal, and low.
Keep in mind that there's a limited supply of CPU time. If you boost the priority of one process, other processes will get less CPU time.
Never set a process to use real time priority. This setting is used for things like the keyboard and mouse drivers that must respond to user input in real time.
Setting other processes to use real time priority can deprive processing time to the point where the system won't run. Likewise, you should only use high priority in situations where it's critical that a process receive as much processor time as possible, and you should avoid manually boosting more than one process to high priority.
Where the Task Manager really shines is in its ability to display exactly how much of the system's resources are being used on a process-by-process basis. Even though you can get similar performance data from the Performance Monitor, its data applies to the system as a whole rather than a single process. For example, consider a situation in which you run the Performance Monitor and realize your system is running low on memory. You can go into the Task Manager and determine exactly which process is consuming the most memory.
If you spot a single process consuming too much memory, you can terminate it with the Task Manager. To view the performance statistics for individual processes, select the Processes tab, then click the Select Columns command from the View menu. As you can see, there's a lot more to the Task Manager than meets the eye. Not only is the Task Manager useful for starting and stopping processes and applications, it's also good for modifying priorities and measuring performance.
Whether you're sleuthing server-performance problems, determining how to tune your system, or sizing a server for new applications, the first step is to learn how to leverage your OS's native performance tools. As Windows NT 4. Although NT 4. If you're familiar with NT 4. Which tool is best for you? Most likely, you'll use both Performance Monitor and Task Manager, depending on your mission.
Performance Monitor is the tool of choice for obtaining detailed information, logging data for extended analysis, and collecting performance information based on performance events that occur within your system. Task Manager provides a quick look into what is occurring on your system, but it doesn't provide a mechanism for logging. However, Task Manager lets you manage applications that is, processes that might be adversely affecting your system.

In multitasking operating systems you sometimes need to find out what processes are running, or you may even need to end one of the processes.
Until Windows XP there were no native commands to manage processes from the command line. There are some very good alternatives available for Windows NT 4 and Some of those will be discussed briefly on this page.
This may prove useful to prevent "killing" itself when "killing" another batch file.
