How to speed up Win7

How can we speed up the speed of Windows7? Everyone wants their computer speed faster, whether it is the speed of the software or the running speed, in the hardware does not become a bottleneck, we can indeed through the means of software to speed up the system. The recent online rumor that shutting down system services can speed up the startup speed and speed of Windows 7 systems is really the case? Let's actually test it.

　The theoretical relationship between service and start-up speed

Services, the system is automatically loaded with some programs, and users start the program compared to their own, it does not appear in the Program window or dialog box, but silently for the operation of other programs to provide background support, only under the Task Manager to show that we are not easy to identify the process.

Several ways to start a service

Press the "Win + R" combination function key to bring up the "Run" dialog box, where you enter "Services.msc" and press ENTER, the Service Management window can appear. Double-click one of the services to view information such as its current status, startup type, and so on, or modify the current state here. The startup type for the service is automatic, automatic (deferred startup), manual, Disabled, and so on.

In automatic mode, the service will run automatically as the system starts, this kind of service is very important to the normal operation of the system, it is reasonable to set this kind of service as the delay-type self starting. There are two ways to start a service that is started manually. One is the true meaning of manual, for example: "Application IdentIT" service, only manually open it, AppLocker (application control Policy, one of the new features of Windows 7) to run.

Relationship between service and system running speed theory

Service is also a special program, its operation will occupy a certain CPU, memory and other resources. From the previous analysis, the startup type is a manual service, and its operation is entirely determined by the user, even if the system resources have to endure.

Selectively disabling these services for automatic or delayed startup does speed up the system's startup speed, and we will test it to speed up the system.

　Second, which services can be closed, shutdown can speed up speed?

While Microsoft is designing Windows 7 o'clock, the starting service is for most users, but not all users need these services in practical applications, and for this we will selectively turn off some services--only for services that are started automatically or delayed.

After turning off the services in the previous table, after 10 Tests, My Computer startup time (on the power switch to the desktop) is about 36 seconds, and 47 seconds before the shutdown does speed up the system. Of course, the actual configuration of each person's computer is not the same, so this data is for reference only.

Finally, it is a certain risk to modify the startup state of the service. Be sure to see the description information and dependencies of the service as you modify it. In addition, before you modify, click action → export list in the Service Settings window. Next, select the save type as a text file (comma-delimited) (*. CSV), and 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 with Excel. If the problem occurs because of a modification to the service, check the original status of the Restore service.

　Third, the service and the system running speed simulation test

The start of a service will certainly occupy a certain amount of CPU and memory resources, the specific occupation of how much, generally can only be tested when the system is fully booted. To do this, we will simulate the test, using the base filtering Engine (BFE) service as an example to illustrate its approach.

Step 1th: Locate and double-click the BFE service (already in the startup state) in the service item, and in the pop-up dialog box, under the General tab, query to the path to its executable file c:windowssystem32svchost.exe-k Localservicenonetwork ", it is the BFE service corresponding process.

The 2nd step: Press "Ctrl+alt+del" combination function key to pull out task Manager, click "view → select column", check the "command line" under it, so that Task Manager can display the service process through the service executable path. In this case, "C:windowssystem32svchost.exe-k local-

Servicenonetwork "namely the BFE Service CPU occupancy rate is 0%, the memory footprint is 5528KB, obviously, when BFE has started the resource usage is very small."

3rd Step: Manually stop the BFE service, and then enable it, to remind you that you can see in Task Manager BFE the corresponding process CPU utilization is 12%, memory footprint is about 8590KB.

Similarly, you can see the CPU and memory resource usage of other services, and the results are similar. To this end, it is not difficult to draw a conclusion:

1. The CPU usage is very low when the process is enabled, almost 0. However, the CPU and memory footprint are larger during activation. Obviously, the services that are automatically enabled will slow down the startup speed of the system, but they can affect the speed of the system after startup.

2. For a service that is manually enabled, it will not be enabled in parallel, and will not have much impact on the speed of the system, and the services are enabled by manual or corresponding programs, and are forced to take up more resources.

3. To speed up system startup, work only on disabling the enabled service.
