Let's take a look at the resources currently available in your system: my computer-> Control panel->; System, select performance, and the current usage of your system can be seen in "System Resources". As long as it is turned on, before running any program, this percentage exceeds 90%, which means that your system is well optimized and not occupied by some background junk programs.

If your percentage is less than 50%, then your system resources are wasted quite seriously. Open more windows and run more programs, and your system will enter an unstable state, which will naturally crash and restart automatically.

Although there are many system optimization softwares that can automatically optimize the system, it is inevitable that the registry will be directly operated, and even the system cannot be restarted! If you want to learn something, you'd better do it yourself.

First look at the taskbar at the bottom right of the screen. There are several background tasks that occupy system resources, and many of these programs are used less.

Although the background programs such as the StartCenter of RealPlayer, the agent of Winamp, and the automatic diagnosis test of Super-Jieba claim to speed up the startup of their own programs and provide related functions of automatically monitoring and opening files, the actual use effect is not significant, but it takes up a lot of system resources. It is recommended to keep only some necessary background programs, such as firewall and antivirus.

How to close some unnecessary programs that exist as soon as they are started? Let's take a look first: Start-> Program-> Start, basically everything in it can be deleted, especially some programs that consume special resources such as "office startup" and "file retrieval" Unless you want to run the program as soon as you start the machine.

Many background programs in the taskbar don't start like this. To delete them, you must process the registry. Registry is an important place for Windows system series to save system software and hardware configuration information. Incorrect operation may lead to disastrous consequences. Fortunately, Windows itself provides an application that can safely operate the startup project, that is, "System Configuration User". It can be started in the following ways: Start-& gt；; Run, enter "msconfig" and confirm.

You can see that there are six labels: general, Config.sys, Autoexec.bat, System.ini, Win.ini, startup. We have to deal with three tabs: Config.sys, Autoexec.bat and start. In fact, the items in Config.sys and Autoexec.bat can be unchecked, that is, all tick marks can be removed.

Enter the "Start" tab, and you can remove the box in front of the items irrelevant to normal operation. After confirmation, it needs to be restarted to take effect. Restart, and then look at the available resources of the system, is there a big change!

Of course, some special background programs still cannot be handled in this way. For example, in the StartCenter of RealPlayer, although the option can be removed from the "Start" tab, a line will be automatically added after restarting. In order to get rid of it, it is necessary to configure it in its running program.

Second, improve the performance of the file system.

Setting the machine file system as a network server allows Windows to use more physical memory for disk pre-reading (including CDs). However, Windows does not occupy the memory required by its applications, but automatically adapts to the memory requirements of various applications.

The specific method is as follows: My computer-> Control panel->; System, select the performance tab and click the file system button, select the network server from the drop-down list, and then confirm. This setting will take effect after a reboot.

Third, open the DMA mode of the file system.

This feature is aimed at Direct Memory Access (DMA, abbreviation of direct memory access) of hard disk and optical drive to maximize system performance, because the biggest bottleneck of personal computer now is the input and output of disk. DMA allows the PC to directly access the data on the hard disk drive, but it does not take up too much CPU time (compared with PIO mode) so that your CPU can perform other tasks.

The specific method is as follows: My computer-> Control panel->; System, select the "Device Manager" tab, expand the hard disk controller or CDROM item, select the corresponding driving device in the expansion, click "Properties", then select "Settings" and select the DMA check box, and then restart.

Of course, you should use DMA, and your CDROM and hard disk should support the corresponding functions. If your CD-ROM drive and hard disk are too old, you may not enjoy the benefits of this function.

Fourth, defragment the disk.

Windows9x series uses the FAT file system. Because of the existence of linked list, all sectors of the file are stored continuously at the beginning. However, as more files are created and deleted, newly created files begin to be distributed in discontinuous disk sectors, with sectors of other files and/or empty sectors in the middle. The more file operations, the more discrete empty sectors are scattered, which is called disk fragmentation. Not literally "there are small physical fragments on the disk"!

Defragmentation is to move files, so that files can be stored continuously by sectors, so that blank sectors can be gathered together, which reduces the time for moving the positioning head when the system reads and writes files, thus improving the reading and writing time of files.

Although Windows also provides a "Disk Defragmenter" to defragment disks, the algorithm of this program is rather stupid, which is not only time-consuming, but also prone to a lot of disk fragmentation after defragmentation.

You can use many disk defragmentation tools provided by third parties, such as Norton's Speeded Disk, which is fast and efficient. In addition, it is recommended to close any windows and background programs, such as antivirus software and network firewall, when tidying up the disk. Because these background programs will read and write disks from time to time. When the defragmenter detects a disk read or write operation, it will restart defragmentation.

After the above processing, I believe your system has been optimized to a considerable extent. When you run some big programs and open more windows, do you realize that it is different from before?
