At the beginning of the purchase, the huge memory with "extremely fast" speed, why did it run slower and slower? Running a program is like an old cow pulling a cart. In order to spare you the pain of buying new memory, this newspaper specially interviewed Liu Lei, a computer expert in the Computer Department of Beijing University of Technology, and asked him to suggest some ways to improve the computer speed without spending money.

System files "bear the brunt"

The operating system of home computers ranges from windows95 to windows98 and windowsXP, which are widely used now. With the powerful functions of the system, the files of the operating system are more and more "occupied". Deleting unnecessary "trivialities" in the usual system will reduce the load of system operation.

Tips: There are nearly 250MB files in the "ystem32dllcache" directory of system files, which are used to restore the system files of windowsXP. Users who use computers normally don't need them at all. They can back them up to other places and delete them from the system files, and the system will be "refreshed" immediately.

Temporary file

Delete it if you want.

In order to open the webpage quickly every time you surf the Internet, many websites will automatically save "temporary files" of the fixed content of the website for users who surf the Internet. But if every website will store "temporary files", it will be a heavy burden on the computer's memory.

Tips: Computer users can completely delete the "temporary files" of websites they don't visit frequently. Users can first open IE browser, select Internet Options from the Tools menu, and delete the webpage files in the Temporary Internet Files column.

Anti-virus removal of backdoor program

Another factor that affects the running speed of windows system is the backdoor program that some websites "implant" when logging in. This backdoor program sometimes starts at startup, which affects the startup speed, and sometimes starts when the webpage is opened, causing the computer to crash.

Tips: users should pay attention to killing viruses frequently when using. This kind of less aggressive backdoor program can generally be found by antivirus software. Users can also select "Show All Files and Folders" in the "Folders" option in "Tools" in daily use, so that all hidden programs are exposed, and users can delete useless hidden programs in time.
