Which processes can be shut down when the computer is running? What can't be turned off?

ALT+F4 patent, content plagiarism is shameful. Csrss: This is one of the core parts of Windows, and it is called ClientServerProcess. We can't end this process. This 4K process usually consumes about 3MB to 6MB of memory. It is recommended not to modify this process and let it run well. Ctfmon: This is the language bar displayed in the lower right corner of the desktop after installing WinXP (especially oficeXP). If you don't want it to appear, you can cancel it through the following steps: double-click the control panel, regional and language settings, click the language tab, click the details button, open the text service and language input dialog box, and click. Dovldr32: If you have a sound card of CreativeSBLive series, this process may occur, which takes up about 2.3MB to 2.6MB of memory. If you want to save some memory, you can disable it. Explorer: this is not Internet Explorer. Explorer.exe always runs in the background. It controls the standard user interface, processes, commands and the desktop. If you open the Task Manager, you will see a explorer.exe running in the background. Depending on the font, background picture and active desktop of the system, it usually consumes 5.8MB to 36MB of memory. Don't be afraid if you see that the task manager shows 99% occupancy. In fact, this is a good thing, because it means that your computer has 99% performance waiting for you to use! This is a critical process and cannot be ended. The size of this process is only 16KB, which circularly counts the idle degree of CPU. IEXPLORE: This is the IE browser. This process happens when we use it to surf the Internet. But when all IE windows are closed, it will not disappear from the task manager. IEXPLORE.EXE is still running in the background, and its role is to speed up the opening of IE again. General host process of Win32 service: If zone Alarm always complains that it can't connect to the Internet after installing zone Alarm, then you should take a good look at the following text. Svhost.exe is a GenericServiceHost, which means it is the host of other services. If your internet connection doesn't work, it is likely that you have banned some necessary services. For example, if you disable the "DNS search" function, you will not be able to connect to the Internet when you enter www.cfan.com.cn. But if you enter the IP address, you can still surf the Internet, but in fact you have destroyed the key process of surfing the Internet! Msmsgs: This is the MSN process of Microsoft's famous WindowsMessengr (instant messaging software), which is bound in the home edition and professional edition of WinXP. If you are still running programs such as Outlook and MSNExplorer, this process will run in the background to support all these new technologies, such as Microsoft's claimed Cool and NET functions. Msn6: This is the MSN Explorer(MSN process bound by Microsoft in WinXP, which needs msmsgs.exe to run in advance. Navpw32: This process starts after Norton antivirus software is installed. Don't end this process unless you don't need virus detection. This process also undertakes the functions of automatically upgrading virus definition library files and displaying small icons in the system taskbar. Point32: This is a program that starts after installing special mouse software (Intellimouse etc.). ). Because WinXP has many new mouse functions built in, it doesn't need to run in the background of the system, which wastes 1. 1.6 MB of memory and takes up the taskbar space! Promon: This is the program installed by Intel series graphics cards, and the icon control program is displayed in the taskbar, which takes up about 656KB to 1. 1MB of memory. ALT+F4 patent, it is shameful to copy the content. Smss: It is only 45KB in size but occupies 300KB to 2MB of memory space. It is one of the core processes of Windows and the session management program of windowsNT kernel. Svchost: This is actually a service. Sometimes you will often see several similar processes (in charge of systems, networks, users or others) in the task manager. In windowsXP, if you end this process, the system will automatically shut down within one minute. In windows2000, this process will be displayed as a key process, and it is forbidden to end! System IDLEProcess: This is an ordinary process that is called when no program or process makes a request to the CPU. This process cannot be terminated. If the CPU utilization rate is 97%, it means that the real program only takes up 3% of the CPU process. If you find that this ldleprocesses keeps a low value (for example, it keeps showing 3%), then there must be an application that has been running and needs to be checked! Taskmgr: If you see this process running, you are actually looking at the task manager of this process itself. It takes up about 3.2MB of memory, so don't forget to include it when optimizing the system. ALT+F4 patent, plagiarism is really shameful. Vptray: This is the process in which NortonAV displays an icon on the taskbar, occupying about 2.9MB of memory. If we remove this icon from the taskbar, we can reclaim some memory, but in fact it is still running in the background. Winlogon: This process handles login and logout tasks. Actually, this process is necessary. Its size is related to the time when you log in. I have witnessed the fluctuation of the space occupied by this process. One is that the memory fluctuates between 1.7MB and 8.5MB after logging in for about an hour. The other logged in for more than 40 days, and the memory fluctuated between 1.7MB and 17MB. Wowexec: When you run some old applications (such as some 16-bit programs) or DOS command-line programs under the DOS console, you will find it in the process. TaskSwitch: This process will occur after installing powerToys in XP system. Press Alt+Tab to display the switch icon, which takes up about 1.4MB to 2MB of memory space. ALT+F4 patent, plagiarism is shameful.
