System Service Optimization Preparation Knowledge

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 do I change the startup type of a service?

In the "Search Programs and Files" column of the Win 7 Start menu, type "services.msc" or "Services" to search for the "Services" item. After clicking, you can 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", "Automatic", "Automatic (Delayed Start)" or "Disabled" (as shown in Figure 1). .

What is the difference between "automatic" and "automatic (delayed start)"?

"Automatic" startup means that the service item is loaded at the same time as 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 Win 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.

What is the difference between "manual" and "disabled"?

When the service startup status is "manual", the process can be activated in certain situations although it is closed, but after the setting is "disabled", the service will not be able to be executed unless the user manually modifies the attribute. run.

Which services need to be manually started?

"Manual" mode, as the name implies, 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". "start up.

This mode is often used when you need to enable some functions that are not turned on. Take the "Application Identity" 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 function will not work.

What should I pay attention to before modifying?

Modifying the system service 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” and select “Save as Type” as TXT text file or CSV file. It is recommended to select the latter. This file can be opened by Excel.

In addition, if there is a situation in which 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.

Not in the LAN to disable the service

Computer Browser, referred to as CB, translated is the meaning of "computer browser", its role is Browse other computers on the LAN and provide a list of computers on the LAN and update them automatically. As the name implies, if your computer is on a local area network, then you need the support of this service to view other computers on the LAN (that is, to view network neighborhoods). But if your computer is not in a LAN environment, it is only running on a stand-alone basis, then the service can obviously be disabled.

Similar to the HomeGroup Listener (Home Group Listening Service, HL for short) and HomeGroup Provider (Home Group Support Service, HP for short), the former is to maintain the association configuration between the home group computers. Receiving services for family groups; the latter's role is to perform tasks related to the configuration and maintenance of family groups. If your computer is not in a family group, you can of course disable it.

Tip: All three services involve LAN and family groups. Readers can choose to disable or set to "manual" mode according to their actual situation. It is recommended that if it is a desktop computer, you can choose to disable it. If it is a notebook, don't disable it, especially the Computer Browser service. After all, the notebook is often connected to other networks.

At the same time, you can also disable Offline Files (referred to as OF, offline file service) and Server services. The former's role is to cache the shared content on the network locally, so that users can access shared files offline; the latter is to allow computers to share files over the network.

Disabled functions are all disabled

Although Win 7 provides a lot of functions, but we may not use them in peacetime, we can selectively turn off these services to achieve effective savings. The purpose of system resources.

If your computer is a desktop or does not have a power management policy enabled, you can choose to disable the Power service; if your computer is not connected to a printer, you can choose to disable the Print Spooler service, which is used to file Loaded into memory for later printing; if you don't use a tablet or a tablet, you can disable the Tablet PC Input Service, which provides tablet support and pen touch sensing; if you rarely use mobile Large-capacity mobile storage devices such as hard disks can also disable the Portable Device Enumerator Service, a service that provides synchronization of removable mass storage devices.

In addition, if the system's automatic update function has been turned off, you can also choose to disable the Background Intelligent Transfer Service (BITS) service, which is used to transfer customers in the background using idle network bandwidth. The data between the terminal and the server is mainly to support the Windows Update function of the system.

Tip: Turning off the BITS service may cause some applications that rely on the BITS service to not automatically update or download updates. If the user is unable to update some software after disabling the service, you can choose to restart the service.

In addition to these services, if you do not use the Windows Media Player media library network sharing function provided by Win 7, you can also disable the Windows Media Player Network Sharing Service, which is even more disabled for stand-alone users.
