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, the online rumor closure system service can speed up the startup speed and running speed of Windows 7 system. Is this really true? Let's take a practical test.
First, the theoretical relationship between service and startup speed
service, is the system automatically loaded some programs, compared with the user-started program, it does not appear program window or dialog box, but silently for other The running of the program provides background support, and only the processes that we don't easily recognize are displayed under the task manager.
How to start the service
Press the “Win + R” combination function button to call up the “Run” dialog box, enter “ldquo;services.msc” in it and press the Enter key to view the service management window. Can 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", "Don't".
In the automatic mode, the service will automatically run as the system starts. Such services are crucial to the normal operation of the system. It is perfectly reasonable to set such services as delayed self-starting. There are two ways to start a service for a manually started service. One is the real meaning of the manual, such as: "Application Identit" service, only manually open it, AppLocker (application control strategy, one of the new features of Windows 7) can run.
The relationship between service and system operation speed
Service is also a special program, its operation will inevitably occupy certain 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?
Microsoft designed the Windows 7 self-starting service for most users, but in practice, not all users need these services. For this, we will selectively turn off some services —— only for services that start in automatic or delayed startup.
After closing the service in the above table, after 10 tests, my computer startup time (pressing the power switch to the desktop) is about 36 seconds, and before closing, it is 47 seconds, which 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 & "dependency" In addition, before the modification, please click “Action → Export List” in the service settings 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 the problem occurs due to the modification of the service, please check the original status of the recovery service.

Three, service and system running speed simulation test
A service start must occupy a certain amount of CPU and memory resources, the specific occupation, generally only in the system completely Can only be tested after startup. To this end, we will simulate it. The following is a description of the Base Filtering Engine (BFE) service.
Step 1: Find and double-click the BFE service in the service item (already started), and query the path of the executable file under the “General” tab of the pop-up dialog box. “C:Windowssystem32svchost.exe -k LocalServiceNoNetwork”, which is the process corresponding to the BFE service.
Step 2: Press “Ctrl+Alt+Del” to combine the function keys to call up the task manager, click “View → Select Columns >, check the “command line” The task manager can display the progress of the service through the executable path of the service. In this example, “C:Windowssystem32svchost.exe -k Local-
ServiceNoNetwork” that is, the CPU usage of the BFE service is 0%, and the memory usage is 5528KB. Obviously, when the BFE is started, the resource occupancy is very small. of.
Step 3: Manually stop the BFE service, and then enable it to remind everyone that the CPU usage of the BFE-related process is 12% and the memory usage is about 8590KB in the task manager.
Similarly, you can view the CPU and memory resource usage of other services, and the results are similar. For this reason, it is not difficult to conclude:
1. When the process is enabled, the CPU usage is very low, almost 0. However, the CPU and memory usage are relatively large during the process of enabling. Obviously, the automatically enabled service will slow down the system's startup speed, but the impact on the system's running speed after startup is very good.
2. For manually enabled services, it will hardly be enabled in parallel at the same time, and the system will not run at the same speed. There will be too much impact. Besides, these services are enabled by manual or corresponding program running. They have to be enabled, and they have to bear more resources.
3. To speed up the system startup speed, only work on disabling self-enabled services.
