It has been three years since Microsoft officially released Windows 7, but it is undeniable that many friends still run Win7 on low-profile computers. Let the small 7 run more smoothly?

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 change the startup type of the service?
Enter ""services.msc” or"service” in the "Search programs and files" column of the Win7 start menu to search for <;service&rdquo ; item, 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 ;
<;Auto & rdquo; & "Automatic (Delayed Startup)" What's the difference?
<Automatic" The program that runs on it. 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 “Disabling "Disabling" What is the difference?
In the case of a service startup status of "manual", although the process is closed, it can still be activated under certain circumstances. After setting to “Disable", the service will not run unless the user manually modifies the properties.
Which services need to be manually started?
“Manual” mode, as the name implies, this service will not be loaded with the system startup, but need to be activated by other services or after the user enters the service management interface, manually start It either modifies its properties to "automatic" to start.

When this mode is often used in some systems had no need to open the open function. 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 modifying?
Modifying system services may cause some unexpected problems, so it is best to back up the default service status 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 the safe mode and the service startup property in the safe mode.
