Try to analyze the reason why the system slows down.

The Windows operating system has been used for a long time. Not only does it start up and slow down, but even the shutdown is very slow. This article tells you why the computer is slowing down.

We know that Windows 2000 and its operating system will go through a series of operations such as logout and save user settings before shutting down. It takes a certain amount of time, so the logout speed is too slow and has become a lot of users. Heart disease. In fact, many cases are caused by user profiles not being released in time.

First, the system itself causes the system to slow down. Some hardware devices of the computer are not completely installed or have problems. The solution to the problem is to check the computer device manager to see if there are any hardware devices with driver problems. If so, please reinstall the related drivers.

Second, the reason for running the software in the background causes the system to slow down. The main reason is that some background running software is running when it is shut down. It takes time for the system to end these programs, such as some anti-virus software. In addition, there may be an error in the background when ending a program, the system process is in an infinite loop, and the system's default forced end of the infinite loop will cause the system to shut down for too long. The solution is to open the task manager when shutting down, see what non-systematic programs are running, and force the process to end. You can also use the auxiliary software such as Super Rabbit to speed up the system shutdown.

Third, the configuration file file causes the system to slow down. When we log in to Windows with our own username, we will run many programs to complete various tasks. When you opt out of the current login (for example, shutdown, reboot, or logout), the normal situation should be that Windows releases all resources (such as memory space) that are used by the open program. If the operation of this step is still not completed when the user logs out, the user profile cannot be uninstalled, and Windows will remain at the step of logging out the user.

There are many reasons for this. It may be caused by the operating system itself, or it may be caused by incorrect encoding of third-party software (such as printer drivers, virus scanners, etc.). But only through the relevant information provided by the system, it is impossible to find out the real "killer", naturally, there is no way to go to the "precautionary medicine" to solve the problem.

Paging file emptying Windows XP operating system needs to clear the temporary data in the paging file (pagefile.sys) when shutting down, because there may be sensitive information, which is correct.

If you do not want Windows XP to perform this step when shutting down, set the value of leanPageFileAtShutdown to 0 in the registry HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\SessionManager\\Memory Management. This will shut down a lot faster.

In addition, to see if there are some unnecessary services, Windows XP must let them end first (within a certain period of time) before each shutdown, reduce unnecessary services, and reduce the time for Windows shutdown.

Fourth, the Vidia graphics card caused the system to slow down Some users have realized that the computer shutdown will become very slow after installing Windows XP. If you install a Vidia graphics card, you have to find it. Many times this is caused by a service called "NVIDIA Driver Helper Service". This service is generally not needed, and it takes up a lot of system resources. To close it, open “Control Panel →Administrative Tools →Services", find and right-click the NVIDIA Driver Helper Service item in the pop-up window, select “Properties>, in the launched drop-down list box, Select “disabled”.

V. Calling dll too much causes the system to slow down pcppp.com Tips: dll introduction, dynamic link library is the basis of the entire operating system, then what is the role? In the dos era, the programmer is By writing a program to achieve the intended purpose, you need to write a program for each purpose. If you go on, it's simple, if it's a complicated program, it's not a waste of time and a waste of youth. So the clever programmers came up with a way to store the program modules that implement certain functions in a file, stored in the dll as API functions. When writing the program, you need to use this function, then directly from This file can be called, so there is a dll—— dynamic link library.

dll role:

After a few modules are pressed into the dll file, you only need to call the dynamic link library when you want to run the program, and you do not need to load the dll into the memory. In the middle, save a lot of memory space, you can easily run other programs. From Xiaohu.com www.xiaohupc.cn

www.xiaohupc.cn Two big games, usually need to call a lot of dynamics To achieve such an effect, many programmers need to write different dlls to help each other, then these dlls can be done with vc++, vb, Delphi, asm, etc., as long as each programmer is responsible for writing a function, so just call together More convenient, save a lot of manpower, material resources, financial resources link library to give players a beautiful and shocking effect
