Which win7 system services are disabled to optimize the system

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 Support for 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?

Enter “services.msc” or "service" in the "Search programs and files" column of the Win 7 Start menu. You can 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 ; The latest xp system download.

<;Auto & rdquo; & "Automatic (Delayed Startup)" What is the difference?

“Automatic"Starting means that the service item is loaded at the same time when the computer starts up so that Support for other programs that run 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” & "Disable" What is the difference?

In the case where the service startup status is "Manual", the process is still closed but can still be specific The situation is activated, and when set to “disabled, the service will not run unless the user manually modifies the properties.

Which services need to be manually started?

“Manual” mode, as the name suggests, this service does not load as the system boots, but requires other services to be activated or accessed by the user. After managing the interface, manually launch it or modify its properties to "Automatic" to start.

This mode is often used when you need to turn on some features that were 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 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 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", 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 the system fails to enter the system due to a modification error, you can press F8 to select the safe mode and the service startup property in the security mode.

Hands-on operating system service I control

Not in the LAN to disable services

Computer Browser, referred to as CB, translated is the meaning of "computer browser", its The role is to 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 HomeGroupProvider (Home Group Support Service, HP for short), the former is to maintain the association configuration between the home group computers. The home group provides receiving services; the latter serves to perform tasks related to the configuration and maintenance of the home group. 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 ComputerBrowser 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 features are all disabled

Although Win 7 provides a lot of features, 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 PrintSpooler service, which is used to load files. In-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 functionality; if you rarely use a mobile hard drive Such as large-capacity mobile storage devices, you can also disable the PortableDevice Enumerator Service, which is 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 IntelligentTransfer Service (BITS) service, which uses the idle network bandwidth to transmit clients in the background. The data between the server and the server is mainly to support the WindowsUpdate 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 This ban is forbidden

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

The 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 tool will not work properly and will prompt “diagnostic policy service has been Disabled ”.

In addition to the DPS service, we can also turn off the Diagnostic Service Host service at the same time. Its role is to analyze the cause of the failure. Also similar is the DiagnosticSystem Host, a system component diagnostic service. Its role is to detect problems with Windows components, troubleshoot and provide solutions. Under normal circumstances, it is not used, and similar to the DPS service, the chances of solving the problem are not large, so you can choose to disable.

If the DPS service still has some effect, then the Distributed Link Tracking Client (DLTC) service can be said to have no effect at all! Its main role is to maintain the internal computer or LAN. A link between NTFS file system files in the internal computer. To put it bluntly, shortcuts, object links, and embedded links are still valid after the target file is renamed or moved. Moreover, in the LAN, only all computers have the service enabled, so it can be completely disabled.

In addition, it can be compared with the DLTC service, "Is it beautiful", I am afraid it will be counted as Windows Error Reporting Service (Windows System Error Reporting Service) service! This service is believed to be familiar to everyone, its role is in Reports errors when the program stops running or stops responding, and allows solutions to be provided, as well as corresponding error logs and reports. Have you used it? So forbidden, don't hesitate!

Autoplay disables safer

Shell Hardware Detection, hardware detection service, SHD for short, its role is The auto-playing device or hardware provides notifications, which is the common operation prompt that pops up after inserting the flash memory (as shown in Figure 3). If you think that this hint doesn't have much practical meaning, or even an annoying tip, simply disable it so that you don't have any hints when you connect to flash or removable devices in the future.

Tip: Disabling this feature disables the autoplay feature and can reduce the risk of system poisoning to a certain extent. Why not?

If you turn off the SHD service first, Then the system may also prompt you to link the Windows Image Acquisition (WIA) service, which provides image capture services for scanners and cameras. In general, if your computer is not connected to a scanner, you can turn it off. Ordinary users generally do not connect to the camera, because copying pictures is usually done using a card reader.

Tip: The service defaults to the "manual" status. If you connect the scanner, you don't need to change the status of the service. If you don't have the option to manually change it to "disable".

Search features vary from person to person

The search function provided in Win 7 (Windows Search) has made great progress, but different users may have different positioning for this function. If the user needs to use this function to search for documents and the like frequently, then the status quo can be maintained (delayed startup); if the user rarely uses the search function of Win7, then the service can be disabled.

Install Killing Software Disable Firewall Service

Windows Firewall, the Windows Firewall service we know well, it doesn't need to say more about —— Windows' basic defense system. However, if you are using third-party anti-virus software and firewall, then you can consider turning off the Windows Firewall service, because in general, third-party anti-virus software and firewalls can completely replace the system firewall that comes with Windows, and the effect is better than Windows firewall. better.

Tip: Some third-party anti-virus software will prompt you to turn off the firewall that comes with the system during installation. However, after shutting down the Windows firewall, the Windows Firewall service is not turned off. This creates a waste of resources in the invisible. Therefore, in the actual use process, after installing the third-party anti-virus software, you can choose to manually close the Windows Firewall service (set the startup mode to "disable".

Disabling services is obvious

In this article, we have listed nearly 20 system services that can be disabled. After personal testing, after shutting down these system services, the system startup speed was significantly faster — — computer startup time was reduced from the original 58 seconds to 50 seconds. Of course, this time will vary depending on the configuration of the computer, but I believe that for some users with relatively low configuration, the effect will be more obvious!
