3. Close the debugger, Dr. Watson.
Dr.Watson is a crash analysis tool of Windows XP, which will automatically pop up when the application crashes. By default, the memory related to the error will be saved as a dump file for programmers to analyze. However, recording dump files will not help ordinary users, but will bring great inconvenience: because Dr. Watson will record the memory when the application crashes, it will take a long time to read and write from the hard disk, and it will take a long time to close the program, and dump files will take up a lot of disk space.
Close the debugger Dr. Watson: run drwtsn32 and delete everything except "dump all thread contexts". Otherwise, once a program goes wrong, the hard disk will ring for a long time and take up a lot of space. If you have encountered this situation before, please find the user.dmp file to delete, which may save tens of meters of space. This is the scene of the wrong program, which is useless to us. In addition, the memory.dmp that appears when the screen is blue can also be deleted. You can turn off the dump when you turn off BSOD in My Computer/Properties. To close Dr.Watson, you can open the registry editor, find the branch of "HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ current version \ AEDebug", double-click the Auto key name under it, change its "numerical data" to 0, and finally press F5 to refresh the setting to take effect, thus canceling its operation. Similarly, we can cancel all options with debugging function when the screen is blue, such as memory.dmp. We can select the Advanced tab in the system properties dialog box, click the Settings button in the startup and recovery column, and select "Write debugging information" as "None" in the startup and recovery dialog box that pops up.
4. Turn off system backup. Right-click my computer, select Properties, and under the System Backup tab, select Turn off system backup for each drive, which can save a lot of hard disk space. (Used)
5. Optimize system properties
Right click on my computer. Under the "Properties-Advanced-Appearance Effects" tab, you can choose the appropriate appearance according to the machine and your own performance. (Used)
Under the Advanced tab, select the application under application response and the application in memory use, so that the system will allocate more resources to the foreground program to make it run faster.
Select the change option under Virtual Memory under the Advanced tab, and set the value of virtual memory to 2.5 times of your physical memory, and the maximum value is the same as the minimum value; And try to avoid setting virtual memory on the same partition as system files. (Used)
6. Invalidate the reading ability of ZIP documents
By default, Windows XP turns on support for ZIP files, which takes up some system resources. You can choose Start → Run, type "regsvr32/u zipfldr.dll" in the Run dialog box, and press Enter to cancel XP's support for zip decompression, thus saving system resources.
7. Clear the page file when closing.
Open the control panel, click Administrative Tools → Local Security Policy → Local Policy → Security Options, double-click the "Shut Down: Clean up Virtual Memory Page Files" item, click the "Enable" option in the pop-up menu, and then click "OK". (Used)
8. Use a simple interface
Although the default appearance scheme of Windows XP is beautiful, it also takes up a lot of system resources, so it can be changed into a classic appearance to get better performance.
Right-click an empty place on the desktop and select the "Properties" command from the pop-up shortcut menu to open the "Display Properties" dialog box. Select "Windows Classic" as the theme on the Theme tab, and change the appearance to a more economical Windows Classic appearance.
9. Speed up the menu display.
Run the Registry Editor and enter "HKEY _ Current _ User \ Control Panel \ Desktop" to change the data value named MenuShowDelay from the original default value of 400 to 0. After the modification, the display speed of XP start menu and even the menu of application software will be obviously accelerated.
10. Accelerated window display
We can change the pop-up of the window from the taskbar and minimize the action of returning to the taskbar by modifying the registry. The steps are as follows: Open the Registry Editor, find the subbranch of HKEY _ Current _ User \ Control Panel \ Desktop \ windowmetrics, and find the MinAniMate key value in the window on the right, with the type of REG_SZ. By default, the value of this key value is 1, which means that the animation displayed in the window is open. If it is changed to 0, animation will be prohibited. Then, select the Logout command from the Start menu to activate the changes you just made. (Used)
1 1. Enable DMA transfer mode.
The so-called DMA, that is, direct memory storage mode, means that computer peripherals (mainly hard disks) can directly exchange data with memory, which can speed up the reading and writing speed of hard disks and improve the speed of data transmission.
Open the system properties dialog box, select the device manager button in the hardware tab, open the device manager window, select the IDE ATA/ATAPI controller in the device list, double-click the main IDE channel or the auxiliary IDE channel, and check whether DMA mode has been started in the advanced settings tab of its properties dialog box. Generally speaking, if the device supports it, it will. (This machine has been set automatically)
12. Reduce the pre-reading and waiting time of the progress bar.
A progress bar will appear when Windows XP starts. We can modify the registry so that the progress bar will enter the login screen only once.
Select the Run command from the Start menu, type the regedit command in the Run dialog box, and then press enter to start the Registry Editor and look for:
HKEY _ LOCAL _ MACHINE \ system M \ current Control set \ Control \ Session Manager \ Memory
Management\PrefetchParameters, select the EnablePrefetcher key under it and change its key value to "1". (Used)
13. Reduce the waiting time for scanning the startup disk.
When the restart caused by abnormal shutdown or crash is recorded in the Windows log, the system will automatically run ScanDisk at startup. By default, each partition will wait 10 seconds before scanning. If each partition has to wait 10 seconds to start scanning, plus the time required to scan itself, it will take a long time to complete the startup process. In this case, we can set the waiting time for canceling disk scanning, or even prohibit scanning disk partitions.
Select "Start → Run" and type "chkntfs /t:0" in the run dialog box to set the waiting time of disk scanning to 0; If you want to ignore scanning a partition, such as drive C, when the computer starts, you can enter the command "chkntfs/x c:"; If you want to resume the scanning of drive C, you can use the command "chkntfs /d c:" to restore all the default settings of chkntfs except automatic file check countdown.
14. Set the processor L2 cache capacity.
Windows XP cannot automatically detect the processor's L2 cache capacity, so we need to manually set it in the registry. First, open the registry and find:
"HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management", select "SecondLevelDataCache" under it and set it according to the processor you use. For example, PIII· Copamin/P4 Willamette is "256", Athlon XP is "384" and P4 Northwood is "5 12". (Used)
15. Change the visual effect
Windows XP enables almost all visual effects by default, such as fading in and out and showing shadows under menus. Although these visual effects are beautiful, they will have a certain impact on the system performance, and sometimes even lead to the suspension of application software. Generally speaking, it is recommended to use less or cancel these visual effects.
Select the "My Computer" icon on the desktop, click the right mouse button, and select the "Properties" command in the shortcut menu to open the "System Properties" dialog box. Select the Advanced tab and click the Settings button in the Performance column to open the Performance Options dialog box. You can turn off all visual effects by selecting the "Adjust to Best Performance" radio box, or select "Customize" and then select the visual effects you want.
Open the System properties, open the Advanced tab, click the Settings button in the Performance column, and then open the Performance Options dialog box. After you select Custom in the Visual Effects tab, only the following will be retained: Smooth screen font edge, Use background picture for each folder type, Show semi-transparent selection rectangle and In window. "Use common tasks in folders" and "Use shadows for icon labels on the desktop". Don't check the others. Click "OK" to exit after setting.
16. Reasonable setting of page virtual memory
Also in the Performance Options dialog box, select the Advanced tab, click the Change button in the Virtual Memory column, select the virtual memory as the custom size, and then set its value. In general, it is advisable to set the virtual value to not less than 256M and not more than 382M, and the maximum and minimum values are the same. (You can also consider setting it to 2 times the physical memory, which is better. )
17. Turn off unused equipment.
Windows XP always tries to install and manage drivers for all devices of the computer, which will not only slow down the system startup, but also cause a lot of system resources. In view of this situation, you can disable devices that are not commonly used, such as PCMCIA cards, modems, infrared devices, printer ports (LPT 1) or serial ports (COM 1), by double-clicking the device to be disabled and selecting Do not use this device (disable) in the General tab of its Properties dialog box. Settings will take effect when you restart, and then enable these devices from Device Manager when you need to use them. (printer port (LPT 1) or serial port (COM 1) is used.
18. Turn off error reporting
When the application fails, a window will pop up to send an error report. In fact, such an error report is almost meaningless to ordinary users, and it is a wise choice to close it.
Select the Advanced tab in the system properties dialog box, click the Error Reporting button, select the Disable Error Reporting option in the Error Reporting dialog box that pops up, and finally click OK.
In addition, we can turn off error reporting from the group policy: type gpedit.msc from Run, run the group policy editor, expand the computer configuration → management template → system → error reporting function, double-click the report error in the setting bar on the right, and select the disable radio box in the pop-up properties dialog box to disable error reporting.
19. Eliminate menu delay
Removing the delay when the menu pops up can speed up XP to some extent. The location of the key to be modified is "HKEY _ Current _ User \ Control Panel \ Desktop". Modify the "MenuShowDelay" key under it, change the default 400 to 0, and press F5 to refresh the registry to take effect. (revised to 50)
20. Clear the pre-read file
Although the pre-reading setting of Windows XP can improve the system speed, after a period of use, the number of files in the pre-reading folder will become quite large, resulting in a longer system search time. Moreover, some applications will produce dead-chain files, which will increase the search burden of the system. So these pre-read files should be deleted regularly. The expected files are stored in the Prefetch folder of the Windows XP system folder, and all files under this folder can be deleted.
2 1. Turn off the autoplay function.
In Windows XP, when a CD is inserted into a CD-ROM drive or USB hard drive and connected to a computer, the system will automatically scan the CD-ROM drive or USB hard drive and prompt you whether to play pictures, videos, music and other files inside. If it is a large-capacity USB hard disk with multiple partitions, the scanning time will be longer, and it is very troublesome to manually close the prompt window several times. In this case, we can turn off the automatic playback function of Windows XP.
Run the group policy program. In the left column of the Group Policy window, open the computer configuration, select the system under the management template, then find "Turn off autoplay" in the configuration column on the right, and double-click it to open the "Turn off autoplay properties" dialog box. Select Enable in the Settings tab, and select All Drives in the Turn off AutoPlay drop-down list. In this way, you don't have to worry about the trouble caused by the "automatic play" function of Windows XP in the future.
