Windows 7 system services common sense

Only first understand some of the relevant knowledge of system services, and then can provide targeted Windows7 system service cleaning solution according to the various needs of Windows7 users, improve the speed of Windows7.

What is a service? A service is a program or process used by a system to perform specified system functions. Its function is to support other applications, generally running in the background. The program does not have program windows or dialog boxes compared to the programs that the user runs, and they can only be observed in the Task Manager. How to modify the startup type of the service? In the “Search Programs and Files” section of the Win7 Start menu, type ““services.msc” or “Services” to search for the “Services” item and click to open the Service Management List window. Double-click on any service to view or modify its properties. In the Properties window, you can modify the startup type to “Manual”,“Auto”,“Auto (Delayed Start)” or “Disable&rdquo ; “Automatic "Automatic (delayed start)” What is the difference? “Automatic"Starting means that the service item is loaded simultaneously when the computer starts up to support other programs running on top of this service. And "automatic (delayed start)" is a very user-friendly design in Windows 7. Starting in this way, you can delay the startup of the service item after the system is started for a period of time. It can solve the problem that some low-configuration computers are slow to start or slow to respond after startup because of too many service items. “Manual” and “Disable” What is the difference? In the case where the service startup status is "Manual", although the process is closed, it can still be activated under certain circumstances, and after being set to "Disable", the service will not run unless the user manually modifies the attribute. Which services need to be manually started? “Manual” mode, as the name suggests, is that this service will not be loaded with the system startup, but after other services are activated or the user enters the service management interface, manually start it or modify its properties to “automatic” . This mode is often used when you need to turn on some features that are not turned on. Take the "ApplicationIdentity" service as an example. By default, the service is in the "manual" state, that is, it is not started. However, when users need to use the AppLocker function, they must manually enable this service (modified to “automatic state), otherwise the AppLocker feature will not work. What should I pay attention to before I am modified? Modifying the system service may cause some unexpected problems, so it is best to back up the default service state before modifying. To open the service management window, click “operation →export list", select “save type” for TXT text file or CSV file, it is recommended to select the latter, the file can be opened with Excel. In addition, if there is a situation that the system cannot be entered normally due to a modification error, you can press F8 to select to enter the safe mode and the service startup attribute in the safe mode.
