Windows XP任务经理介绍：过程、节目和表现-第2部分

保证读其他岗位从窗口任务经理系列!

好如此继续从早先岗位结尾节目在任务经理我们在的什么现在击中过程制表符让我们做。

现在，如果您的节目不由点击在，死结尾任务按钮我们结束了说那应用制表符，您在节目能然后用鼠标右键单击和选择“去处理“. 这给过程制表符将带来您，实际上是可执行的在窗口跑为那个特殊节目。

运行那个节目的过程自动地被突出，当您选择去处理选择时。处理制表符提供您详细信息关于跑在系统的每个过程，它是否是用户过程或系统过程。 图象名字 是过程的名字， 用户名 是它是否是用户过程或Windows XP过程， CPU 是特殊应用占去信息处理时间的百分比，和 Mem用法 是多少您的计算机存储器占去。

现在真正地否决节目，您在过程能用鼠标右键单击和选择二者之一 结尾过程 或 末端处理树. 首先尝试结尾过程，并且，如果那不运作尝试结尾过程树。处理树基本上意味着，如果这个过程由某一其他过程开始它，它将设法杀害一切包括父进程。

现在也在这个制表符，您能观看其他信息例如在计算机占去多数CPU或记忆的过程。这可能证明相当有用的，如果您自后安装了两三种应用，并且一切突然爬行。您能点击的倒栽跳水任何专栏排序过程。如此，如果您想要看哪些过程使用CPU，点击CPU专栏，并且您应该看 系统无所事事的过程 在上面。 If you see 0’s, click on it once more to sort high to low.

The System Idle Process is a system process that runs when the computer processor is not being used. You always want that to be fairly high. Also, now you’ll notice that the processes keep shifting up and down and that’s because one becomes active and then might stop and another process does some work, etc. At the bottom of the Task Manager window you’ll see the CPU Usage status. This number should be pretty low for a desktop computer. Less than 15% is a good rule unless you’re running a game or something of that sort. You can also sort the Mem Usage column and see which programs are hogging all of the memory. In my instance, you can see IE is eating up 108MB of RAM!!! That’s a lot!! I’m kinda curious as to why, I only have two windows open.

You’ll also notice that by default there are only four columns listed in the Task Manager for processes. You can actually choose a bunch more columns by clicking on View from the top menu and choosing “Select columns…“.

As you can see, there are a lot of properties for a process that you can view. Some of the more useful ones are PID, Page Faults, Thread Count, and Non-Paged Pool. If you’re interested, you can read more about these by doing a search on Google.

The last thing you can do for a process is to set how much of the CPU you want it to use and which CPU you want a process to run on. Of course, the second statement is only valid if you have a computer with more than one processor, but since dual cores are becoming common now, I figure I can show you how to run an application on just one processor.

If you right click on the process name, you see two options at the bottom, Set Priority and Set Affinity. Priority is exactly that: what kind of privilege do you want to give or take from a process. If you’re running something like an anti-virus scan, but hate the fact that it completely disables your ability to do anything else on the computer until the scan finishes, then you can reduce the priority given to the anti-virus software so that it doesn’t use up everything.

Here I am changing my eTrust anti-virus program to Low, so that it does it’s thing, but not by hogging all the CPU. You can also set the process to run one a particular CPU if you have more than one. Click on Set Affinity and you’ll get a dialog with 32 check boxes with everything disabled except for the number of processors on your computer:

By default, Windows will use the first processor on your computer the most for it’s tasks, so if you want to run a program on it’s own dedicated processor without interfering with Windows work, just uncheck the box for the first processor for that application! Pretty cool!

In the next post, we’ll talk about the Performance tab and Networking tabs.

I know I’m not the only one that this has happened to:

I open “Task Manager” and under the “User Name” column is nothing, absolutely nothing, only “System Idle Process” is assigned a User Name “System”

can you elaborate on how to correct this problem, I do know it has to do with certain windows “services”

Though I’m trying to keep my machine as slim as possible including stopping most of the “services” related to internet / networking etc. the machine is a “Stand alone” w/XP pro sp2 and not conected to anything, the internal LAN is disabled, and there’s no modem either, and I have no intention of ever “connecting” it either.
I had a horrendous time trying to get rid of “(in)Security Center and Firewall” because I don’t need them, and don’t want them.

I’ve seen on forums and other types of boards, some other people who are “connected” that have mentioned this problem about not having any “user name” in the “user name” column and no matter when or what process / program get’s started nothing ever shows up there?
which if no user name is displayed could be masking a security risk like a VNC connection monitoring them.
