Windows 7 system service performance optimization

Now there are quite a few computer users who are not very high in configuration. Windows 7 (hereafter referred to as Win 7) has been officially used. How can I make Win 7 run smoothly on low-profile computers? This article teaches you to manually optimize Win 7, and the object is the most overlooked system service.

We first understand some system knowledge of system services, and then provide targeted Windows7 system service cleaning solutions according to the various needs of Windows7 users to 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" column of the Win 7 Start menu, type "services.msc" or "service" to search for "service" items, click 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", "Auto", "Automatic (Delayed Start)" or "Disable" ;.

"Automatic" and "Automatic (Delayed Startup)" What is the difference?

"Automatic"Startup means that the service is loaded at the same time as the computer starts 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.

"Manual" and "Disable" What is the difference?

When the service startup status is "manual", the process is turned off, but it can still be activated under certain circumstances, and set to "disable", unless the user manually modifies the attribute. Otherwise the service will not run.

Which services need to be manually started?

"Manual" mode, as the name implies, this service does not load as the system boots, but requires other services to be activated or after the user enters the service management interface, manually launch it or modify its properties to "Automatic" Startup. This mode is often used when you need to turn on some features that are not turned on. Take the "Application Identity" service as an example. By default, the service is "manual" status, that is, it is not started. However, when users need to use the AppLocker feature, they must manually enable this service (modified to "automatic" status), otherwise the AppLocker feature will not work properly.

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 "Action → Export List", select "Save Type" for TXT text file or CSV file. It is recommended to select the latter. This file can be opened with Excel.

In addition, if there is a situation that cannot be entered normally due to a modification error, you can press F8 to select to enter safe mode and the service startup property in 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 to browse other computers on the LAN, and provide LAN The list of computers in the list is automatically updated. 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.

It is similar to 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.

Hint: The above three services all 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.

All functions are 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 load files into memory for Print later; 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 functionality; if you rarely use large-capacity mobile storage such as mobile hard drives The device can also disable the Portable Device Enumerator Service, which provides a service for the synchronization of removable mass storage devices.

In addition, if the automatic update function of the system has been turned off, you can also choose to disable the Background IntelligentTransfer Service (BITS) service, which uses the idle network bandwidth to transmit in the background. >

The data between the client 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.

Chicken rib function The ban is forbidden

In addition to the functions that are not commonly used in Win 7, there are some functions that are more ribbed, and you can also choose to disable them.

Diagnostic Policy Service (DPS) service can be completely disabled. It is a service that provides problem detection, troubleshooting, and diagnostic support for Windows components. It is common that when a failure occurs in the system, a dialog box will pop up asking if you need to enable troubleshooting to help you find the cause. Users who have used this feature know that the chances of solving the problem are not great, so disable it!

After disabling the service, the system's diagnostic tools will not function properly and will prompt "Diagnostic Policy Service has been disabled".
