1, set a virtual memory hard disk has a very big data Exchange file, which is reserved for virtual memory by the system. Many applications use it frequently, so the system needs to make a lot of data access to the main memory. Therefore, the speed of accessing this file will affect the speed. Very important factor in the speed of the computer! Generally, Windows
presets the virtual memory to be managed by the system itself. It automatically adjusts the size of the swap file according to the needs of different programs. However, such a large size reduction will impose an additional burden on the system. Make the system slow down! In view of this, users should customize the minimum and maximum values ​​of virtual memory to avoid frequent size changes. To set the virtual memory, right click on the Computer
”"property", in the “ “Virtual memory” set.

2, completely remove the program Everyone knows, if you want to delete some programs, you can go to the "add /remove program" operation, but everyone knows, it will only help you remove the program And will not help you delete the registration code of the program and some login items? To completely remove the program, find some "professional" software to delete! The nortonuninstall produced by symantec, because some parts have destroyed the copyright of some deleted software, so the world has stopped selling, because of this, symantec only came out cleansweep, but on the function, nortonuninstall is even better! Closer to home, in fact, in addition to these two software, there are many similar software can effectively delete the program.

3. Checking the application software or drivers Some programs slow down the system when the computer system starts up. If it is for this reason, we can start from “safe mode”. Because this is the original launch, "safe mode" is running slower than normal. However, if you use “Safe Mode to start and find that the computer starts faster than normal startup, then a program may be the cause of slower system startup.

4, too many desktop icons will cause trouble, too many icons on the desktop will also reduce the system startup speed. Every time Windows starts and displays the desktop, you need to find the icons of the desktop shortcuts one by one and load them. The more icons, the more time it takes. At the same time, some anti-virus software provides the system startup scan function, which will take a lot of time. In fact, if you have already opened the real-time monitoring function of the anti-virus software, then the scanning system will be redundant when booting, or disable this function. ! It is recommended that you put the less commonly used desktop icons in a special folder or simply delete them!

5, ADSL caused the system to start slower

By default, Windows XP will perform self-test on network devices such as network cards when booting.

At this time, we can open the “Local Area Connection” property menu and double-click the “Internet Protocol” option in the “General” menu to open the “TCP/IP Properties” menu. Configure the IP address of the NIC as a value that is not used in the public network (the default gateway is 192.168.1.1), such as 192.168.1.X. X takes a value between 2 and 255. The subnet mask is set to 255.255.255.0, default gateway and DNS default settings.

6, the impact of fonts on speed Although Microsoft claims that Windows operating system
can install 1000 to 1500 fonts, but in fact, when you install more than 500 fonts, there will be problems. For example, fonts disappear from the application's font list and Windows startup speed drops dramatically. It is recommended that you delete the fonts that are not used or are not commonly used. To avoid accidents after deletion, you can make the necessary backups first.

7. Delete the random startup program What is the random startup program? A random starter is a program that is loaded at boot time. Random start program not only slows down the speed of booting, but also consumes computer resources and memory faster. Generally speaking, if you want to delete the random start program, you can go to the "Startup" list to delete, but if you want to be more detailed, for example Is QQ, popkiller and other software, can not be deleted in the "start" list, go to the "subsidiary application", then go to "system tools", then go to “ system information & rdquo;, After entering, press the “Tools” button in the upper toolbar, and then press “System Configuration Editing Program”.

10. Making Windows more slim Compared to DOS, Windows is too big, and with your daily operations, installing new software, loading runtimes, adding new games, etc. makes it even more It's huge, and more importantly, it's not just its directory, but its registry and runtime. Because even if a program is deleted, the DLL file it uses will still exist, so with the use of Windows, the DLL dynamic link library file that needs to be loaded when Windows starts and exits is getting bigger and bigger, and the natural system runs faster. It is getting slower and slower. At this point we need to use some programs to completely remove the DLL, they can make Windows restore a slim figure. It is recommended that the best players should reinstall Windows every two months, which is very effective.
