Comprehensive interpretation of Windows XP services
When optimizing Windows xp systems, you need to close some of the less commonly used services, but in many service projects, what are they used for? of? Can you turn off? This often irks many newbies. The detailed interpretation of the xp system service collected here is intended to help friends who need to optimize the system.
1, Alerter
The process name of the Alerter service is Service.exe (that is, the name of the process running in the background after starting this service, can be seen through the task manager, under with). The function of the Alerter service is that WinXP sends management-related events on the system to the specified computer or user on the network, such as when a printing error occurs or the hard disk is about to be full. Collected and sent by WinXP's Alerter Service. Although the agent-dependent service does not have a Messenger service, the Alerter service must rely on the latter to send information. Therefore, after starting the Alerter service, it must be determined that the Messenger service is also working, and the receiving computer must also start the Messenger service. Since the Alerter service is running, the service is that the user can send "Pop-up" information to other users, and the information may be used by an attacker to perform an attack, such as tricking the user into modifying the password, thereby posing a security risk. At the same time, the service causes the user account to leak, and may also be exploited by the attacker to conduct a password guessing attack. So for home single-user users, even for most small LANs, this feature is completely disableable, which not only saves system resources and speeds up startup, but also improves machine security.
2, Application Layer Gateway Service
Abbreviation "ALG" (application layer gateway) process name is alg.exe, WinXP Home /Pro default installation startup type is manual. ALG is also known as a proxy server (Proxy Server), which is a functional classification of network firewalls. When the internal computer is connected to an external host, the proxy server acts as a connection relay for the internal computer and the external host. The advantage of using ALG is to hide the address of the internal host and prevent externally abnormal connections. If the agent designed for the application is not installed on the proxy server, any packets belonging to this network service will not pass through the firewall. Popularly speaking, specific to ALG itself, it is the specific control procedure for the attached Internet connection sharing/firewall. If you need to start both, this service is a must. Of course, only one computer Internet home can consider disabling this service, but the built-in firewall effect of WinXP is still good, if you are not insisting on using a third-party firewall, or open it.
3, Application Management
AppMent (Application Management Service) process name is Svchost.exe, WinXP Home/Pro default installation start type is manual, there is no dependent service relationship. Starting with Win2000, Microsoft introduced a new and effective software management solution based on the MSI file format (application installation information package file) —— application management component service (Application Management), which not only manages software installation , delete, and use this service to modify, repair existing applications, monitor file recovery and eliminate basic failures through demobilization. Usually this service we keep its default state is better.
Many friends may have the impression that when ACDSee4.0 was first released, due to the lack of consideration in the installation and production, most people’s systems did not support the MSI installation format at that time. I have to download and install an MSI auxiliary file called Windows Installer to solve the problem. Software that is usually installed in the MSI file format is very easy to recognize. For example, Office XP, when you run the software installer again after installation, it generally has "Reinstall", "Repair Software", "Uninstall" Software & rdquo; Multiple options, instead of the previous installer, simply uninstall or overwrite the installation.
4, Automatic Updates
The process name of Wuauserv (automatic update service) is Svchost.exe. The default startup type of WinXP Home/Pro is automatic, without any dependent service relationship. This is a system automatic update function that everyone is very familiar with, so I won't say much. A friend who uses the kitten to surf the Internet and remembers it is not enough to close it in the system properties. It is also necessary to disable the Automatic Updates service. Need to update in the future, enter Windows Update directly in IE
