Now there are quite a few computer users who are not very high in configuration. Windows 7 (hereafter referred to as Win 7), how to make the low configuration computer run Win 7 more smoothly? Some software provides a foolproof optimization method, but these optimizations often make the user unable to find the mind, and do not know whether it is true or not. 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.
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 to modify the startup type of the service?
Enter ""services.msc” or"service” in the "Search Programs and Files" column of the Win 7 Start menu to search for "Services" ” item, you can open the service management list window after clicking. 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.
<quo;Automatic"; &"Automatic (Delayed Startup)" What is the difference?
<;Automatic";Startup means that the service item is loaded at the same time when the computer starts to support other services based on this service. The program that runs on it. 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 “Disabling "Disabling" What is the difference?
The service startup status is "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?
<quo;Manual” mode, as the name suggests, 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.
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 “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 modification?
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 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.
Hand-operated operating system service I control
Not in the LAN disable service
Computer Browser, referred to as CB, translated is the meaning of "computer browser", its role is to browse other computers on the LAN, A list of computers on the LAN is provided and 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 family computers and family groups. The 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: 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.
Unused features All disabled
Although Win 7 provides a lot of functions, but we may not use them in peacetime, then we can selectively turn off these services, thus saving the system resources effectively.
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 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 hard drives, etc. Capacity mobile storage devices 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 uses the idle network bandwidth to transfer clients and servers in the background. The data between the two is mainly to support the system's Windows Update feature.
Hint: Turning off the BITS service may cause some applications that rely on the BITS service to not automatically update or download updates automatically. 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
Win 7 in addition to the functions that are not commonly used, there are some functions that are more ribbed, 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 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 Diagnostic System 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 computer inside or in the computer on the LAN. A link between NTFS file system files. 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, you 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 to stop the program. Or report an error when it stops responding, and allow the solution to be provided, along with the corresponding error log and report. Have you used it? So forbidden, don't hesitate!
Autoplay disables safer
Shell Hardware Detection, hardware detection service, SHD for short, it is used for automatic playback of equipment or hardware Provide notification function, which is the common operation prompt that will pop 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.
Hint: Disabling this function disables the autoplay function. It can also reduce the risk of system poisoning to a certain extent. Why not?
If you close the SHD service first, the system may also prompt you. You need to turn off 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.
Hint: The service defaults to “manual” status. If you connect the scanner, you do not need to modify the status of the service. If you do not have the option to manually change it to “disable”.
Search function varies 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 Win 7, then the service can be disabled.
Installing and killing software Disabled firewall service
Windows Firewall, we are familiar with the Windows Firewall service, it does not 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. The firewall is better.
Hint: 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 closed, which causes 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 the service The effect is obvious
In this article, we have listed a total of 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!
