Encargado de la tarea de Windows Vista
Presione Ctrl-Cambiar de puesto-Salida. Una ventana le abre y presenta con seis lengüetas. Como la mayoría de los administradores de Windows saben ya, usted acaba de abrir a encargado de la tarea de Windows, que presenta una exhibición gráfica de programas, de procesos, y de los servicios abiertos que están funcionando actualmente en su computadora. Ha estado disponible por muchos años en los varios sistemas operativos de Windows, y ahora se ha puesto al día con algunas nuevas características para el lanzamiento de Vista.
La lengüeta de los usos
La lengüeta de los usos es una de las lengüetas más simples visualmente; exhibe una lista de cualesquiera los usos abiertos en orden alfabético, e incluye una columna del estado para indicar si el uso está funcionando o, peor, no está respondiendo.
Los tres botones siguientes aparecen en el fondo de la lengüeta de los usos:
Tarea del final. Éste es el comando más de uso general en la lengüeta de los usos, y ha utilizado para apenas qué el nombre del botón sugiere.
Cambie a. Este botón puede actuar como el equivalente del tirón o del tirón 3D de Windows de Windows.
Seleccione simplemente el uso en la lista del programa y chasque el interruptor para abotonar.
El app seleccionado llega a ser activo.
Nueva tarea. Esto le deja lanzar un nuevo uso que usa una caja de diálogo llamada, crea apropiadamente la nueva tarea, que mira y se comporta exactamente como la caja de diálogo del funcionamiento.
Recuperación de un uso congelado. Una de las razones principales usted visitaría los usos que la lengüeta durante el curso de la localización de averías es cerrar un uso que ha parado responder. Los tecleo-pasos son mínimos, y realmente no han cambiado en esta iteración del encargado de la tarea.
Aquí está cuál a hacer:
1. Abra a encargado de la tarea. Cualquier uso que el atajo del teclado introdujo previamente
(Ctrl-Cambiar de puesto-Salida), o derecho-tecleo el taskbar y eligen a encargado de la tarea del menú del contexto.
2. Elija los usos cuadro. La lengüeta de los usos es el defecto, pero observa que el encargado de la tarea se abre siempre con el cuadro previamente seleccionado.
3. Seleccione el programa con un estado de no responder, y después chasque el botón de la tarea del final.
Observe que usted no conseguirá generalmente ninguna clase de confirmación antes de que el uso se cierre cuando usted está utilizando esta técnica. También, es generalmente una buena idea dar al uso congelado al minuto o dos para intentar resolver la edición en sus el propios, porque el cierre de un programa de esta manera hará cualquier cambio unsaved ser perdido.
Localización de averías de un uso congelado. ¿AUTORIZACIÓN, usted sabe cerrar un uso se congela que, pero no sería incluso mejor si el encargado de la tarea podría ayudarle a calcular hacia fuera porqué el uso congeló en el primer lugar?
Conjetura qué: it’s time to point out one of the new features of Vista’s Task Manager.
You now have the ability to create a dump file for a specific application that’s frozen. You can then use this dump information in a debugging application to determine the root cause of the problem. To create a dump file for a frozen app, just right-click it from the Applications tab and select Create Dump File from the context menu. When the procedure completes.
This will help you retrieve the dump file for later parsing in the debugging app of your choosing. Naturally, interpreting debugging files is something of an art unto itself, and it requires a good understanding of the various operating system mechanisms that govern how data is used and executed. You can find more information on how to use Windows debugging tools at: http://www.microsoft.com/whdc/devtools/debugging/debugstart.mspx
The Processes tab
One of the improvements on the Processes tab is the ability to access the properties of a particular process. To do so, just right-click the process and choose Properties from the context menu. The nice thing about accessing properties for a process is that you can set specific compatibility options for an application’s process. Try this if you can’t get a program to run as well as you’d like.
Setting processor affinity. Another helpful task that you can perform from the Processes tab is setting processor affinity for a particular process. Setting processor affinity should not be a task you perform regularly, but it can be especially helpful in optimizing performance in Vista systems that are running either two processors or single processors with a dual core (Intel’s Core 2 Duo, for instance).
To set processor affinity, right-click the process on the Processes tab and choose Set Processor Affinity from the context menu.
Troubleshooting excessive CPU usage. One of the biggest benefits of the Processes tab is the ability to see how much processing horsepower a particular process is using. Obviously, a process that is taking between 50 and 100 percent of the processing cycles is most likely going to cause problems for anything else running on the system.
Vista tries its best to manage processing time so that all apps and background processes get their instructions processed, but often you’ll notice an app hogging more than its share.
Sometimes it’s easy to tell where the problem lies—the application’s process is taking up a lot of time; killing the process fixes the problem. But at other times, the problem is with related processes such as svchost.exe. Services such as these can sometimes be responsible for hosting multiple child processes, and killing the svchost.exe process can cause a lot of cascading problems.
In this case, two different tools can help. One, of course, is the Task Manager. The other is the Tasklist command, which you can run from the Command Prompt. With these two tools in hand, Vista administrators can quickly pinpoint the problem and correct it.
The Services tab
Similar to the Processes tab, the Services tab lists all services currently running on the computer and lets you sort them according to column headings. You can use the Status column to quickly locate a service that is not running. The Services button on the bottom launches the Services MMC console, which is the same as launching services.msc from the Start menu.
The Performance tab
The Performance tab provides a quick peek into Vista system performance, listing several critical performance parameters and a graph of CPU and processor usage. As Here are a few things to look for:
A flat memory graph. A flat Physical Memory Usage History graph means that open applications aren’t continuously asking for more system memory, also known as a memory leak. A graph that looks like a ramp will lead to poor performance as other applications fight for remaining memory.
The amount of free physical memory As the value approaches zero, memory is running low. You might want to close an application or two, especially one that’s using large amounts of memory.
The physical memory cached. If the value is less than half of the total available memory, Vista is having trouble storing recently used information in memory. Again, the solution here is to close applications you aren’t actively using. Vista gives up some of the system cache when it needs RAM, so closing the programs should alleviate this problem by reducing the demand for RAM.
The Networking tab
The Networking tab provides another graphical representation of performance, this time on the network adapters on your system. On a desktop computer, you might see only one adapter. On a laptop, three (or more) network connections may be displayed: a local area connection, a wireless network connection, and a Bluetooth network connection. The information here will help administrators determine whether a networking connection is being stressed. Such a circumstance would be very rare, and you could address it by disabling the network connection before determining the root cause (i.e., what’s sending all that traffic).
The Users tab
The Users tab is not new to Windows Vista, and it’s used for the same purposes as it was in Windows XP. With the Users tab, administrators can see who is currently logged on or otherwise connected to the Vista machine, and can force such users to either disconnect or log off. You can also send messages to the other users displayed on this tab. It’s often a good idea to send a message to a user before forcibly disconnecting him. This allows the user to close any open work in an orderly fashion rather than risk losing data when the connection is abruptly terminated.
