Using Task Manager to Adjust Priorities
at normal priority, which is right in the middle of the priority spectrum. You can
run applications and assign six different priority levels, ranked from highest
to lowest: Realtime, High, Above Normal, Normal, Below Normal, and Low.
Because the CPU can do only one thing at a time, the different priority levels
allow the operating system to decide which application gets the next CPU time
slot. If an application is running at the High or Above Normal priority levels, it
gets more CPU time than an application running at Normal level.
As you can see, the priority you give an application can affect how fast the
program runs.
Using Task Manager to Adjust Priorities
Windows Task Manager is something that everyone experiences when they have
problems with a frozen program, and you learned that it is a very useful utility.
In Task Manager you can change the priority at which an application is running.
This capability can be very useful when you have a lot of programs running on
your computer.
CAUTION Setting any application to Realtime can be dangerous because doing
so allows the application to hog all the CPU time. Exiting a program that is
running at this high priority is next to impossible if for some reason it crashes or is
stuck in a loop. It takes a very long time to load Task Manager to end the
application because the program is hogging all the CPU time.
If you have an application that has a high need for CPU operations, such as
rendering a video clip or a game, you can adjust the priority of the application
by following these steps:
1. Open the Start screen, type taskmgr , and press Enter.
2. After Task Manager loads, click the Details tab. Be sure to click More
Details to see the full Task Manager.
3. Right-click the name of the process for which you would like to adjust
the priority, select Set Priority, and then select the level, as shown in
Figure 16-11. Your change is now complete.
TIP Having problems identifying which process belongs to an application? While
on the Applications tab of Task Manager, right-click any application and select Go
To Processes. All processes that belong to the application will be selected on the
Processes tab.
