How can I speed up Windows 7 speed

How can I speed up Windows 7? Everyone wants their computer speed to be faster. Whether it is the boot speed or the running speed of the software, after the hardware does not become a bottleneck, we can really speed up the system through software. Recently, online rumors that shutting down system services can speed up the startup speed and speed of Windows 7 systems. Is this really true? Let's take a look at the actual test.

First, the theoretical relationship between service and startup speed

Service, is the program automatically loaded by the system, compared with the user-started program, it will not appear in the program window or dialog box. Instead, it silently provides background support for the running of other programs, and only shows the processes that we are not easy to identify under the task manager.

Several ways to start the service

Press the "Win + R" combination function key to bring up the "Run" dialog box, enter "services.msc" and press the Enter key to serve The management window will appear. Double-click on one of the services to view its current status, startup type, etc., and also modify the current status here. The startup type of the service is "automatic", "automatic (delayed start)", "manual", "disabled", etc.

In the automatic mode, the service will automatically run as the system starts. Such services are crucial to the normal operation of the system. Setting such services to delayed self-starting is also fully consistent. Reasonable. There are two ways to start a service for a manually started service. One is the real manual, such as the "Application Identit" service, which can only be run by manually opening it, AppLocker (application control policy, one of the new features of Windows 7).

The relationship between service and system speed

Service is also a special program, its operation will inevitably occupy a certain amount of CPU, memory and other resources. From the previous analysis, the startup type is a manual service, and its operation is completely determined by the user, and even if it takes up system resources, it has to endure.

For automatic or delayed start-up services, selectively disabling them does speed up the system. As for speeding up the system, we will test it.

Second, which services can be closed, can you speed up the boot speed?

When Microsoft designed Windows 7, the self-starting service was for most users, but in practice, not all users need these services. For this reason, we will selectively shut down some services - Only for services that are initiated automatically or delayed.

After shutting down the service in the above table, after 10 tests, my computer boot time (press the power switch to the desktop) for about 36 seconds, and before shutting down for 47 seconds, it can speed up the system startup. speed. Of course, the actual configuration of each person's computer is different, so this data is for reference only.

The last thing to remind is that there is a certain risk in modifying the startup state of the service. Please be sure to read the "description" information and "dependency" of the service when making changes. In addition, before the modification, please click “Operation→Export List” in the service setting window. Next, select the save type as "text file (comma separated) (*.CSV), then enter the file name and save location to save the current state of the service as a CSV file. This file can be opened by Excel. If serviced If the modification causes the problem to occur, please refer to the original status of the recovery service.

III. Simulation test of service and system running speed

The start of a service will certainly occupy a certain amount of CPU and memory resources, and the specific usage is generally only tested after the system is fully booted. For this, we will perform simulation tests on it. The following is the Base Filtering Engine (BFE) service. Take an example to illustrate its method.

Step 1: Find and double-click the BFE service in the service item (already started), and query it for "executable" under the "General" tab of the pop-up dialog box. The path of the file is "C:Windowssystem32svchost.exe -k LocalServiceNoNetwork", which is the process corresponding to the BFE service.

2 : Press the "Ctrl+Alt+Del" combination function key to call up the task manager, click "View → Select Column", check the "command line" under it, so that the task manager can pass the service executable file. The path to display the service process. In this example, "C: Windowssystem32svchost.exe -k Local-

ServiceNoNetwork" means that the CPU usage of the BFE service is 0%, and the memory usage is 5528KB. Obviously, when The resource usage is very small when the BFE is started.

Step 3: Manually stop the BFE service and then enable it. The Network Academy (http://www.pcedu123.com) reminds everyone that it can be in task management. The CPU usage of the BFE-related process is 12%, and the memory usage is about 8590 KB.
