2. Run the disk defragmenter to defragment and eliminate disk fragmentation.
3. Clear startup items: Start → Run →msconfig→ Start, and close unnecessary startup items.
4. Accelerate startup and shutdown: start the registry editor (Regedit.exe), find HKEY _ current _ user \ control panel \ desktop, and change the numerical data of the string value [HungAppTimeout] to [0] and the numerical data of the string value [WaitToKillAppTimeout] to [1000]. In addition, in HKEY _ local _ machine \ system \ currentcontrolset \ control, the numerical data of the string value [HungAppTimeout] is changed to [0], and the numerical data of the string value [waittokilservicetimeout] is changed to [1].
5. Automatically close the stop response program: start the registry editor, find HKEY _ current _ user \ control panel \ desktop, change the numerical data of the string value [AutoEndTasks] to [20], and then restart. Automatic shutdown stop response program when shutdown: look up HKEY _ user \. Default \ control panel \ desktop (or HKEY _ current _ user \ control panel \ desktop), change the numerical data of [AutoEndTasks] to [1] in the right window, and log off or restart.
6. Clear the unused DLL files in the memory: start the registry editor, find HKEY _ local _ machine \ software \ Microsoft \ Windows \ currentversion \ Explorer, create a new DWORD value [always sunloadDLL], and set its value to [1]. Note: If this value is set to [0], this function will be disabled.
7. Speed up broadband access:
(1) Home Edition: Start the Registry Editor, find HKEY _ local _ machine \ software \ policies \ Microsoft \ Windows, create a new project named [Psched], create a new Dword value [nonbestforlimit] in the right window of [Psched] and set its value to [0].
(2) Business Edition: [Start] → [Run] → type [gpedit.msc], open the local computer policy, select [Computer Configuration] → [Management Template] → [Network ]→[QoS Packet Scheduler] in the left window, double-click "Restrict reserved bandwidth" in the right window, and select "Enable" to limit bandwidth.
8. Fast browsing LAN * * * Enjoy: Start the registry editor and find HKEY _ local _ machine \ software \ Microsoft \ Windows \ current version \ resource manager \ remote computer \ namespace. There is a project under this project {D6277990-4C6A-1KLOC-0/CF-8D87-00A0060F5 BF}. Delete it, restart the computer, Windows XP will no longer check the scheduled tasks, and the speed will be significantly improved.
9. Use the L2 cache of CPU to improve the overall performance: Start the Registry Editor and find HKEY _ Local _ Machine \ System \ Current Control Set \ Control \ Session Manager \ Memory Management in the right window. Change the numerical data of Dword value [SecondLevelDataCache] to the same decimal value as CPU L2 cache: for example, P4 1.6G is 5 12Kb for an L2 cache, and change the numerical data to decimal value [5 12].
10. Run the defragmenter when you start the computer.
Start the registry editor, find HKEY _ local _ machine \ software \ Microsoft \ dfrg \ bootoptimizefunction, and set the string value [Enable] to: [Y] equals on, [N] equals off.
1 1, memory performance optimization
There are several options to optimize memory performance in Windows XP, which are located under the registry: HKEY _ Local _ Machine \ System \ Current Control Set \ Control \ Session Manager \ Memory Management.
(1) Disable the memory paging executor.
In general, XP will write the fragments in the memory to the hard disk, which can prevent it from doing so and keep the data in the memory, thus improving the system performance. Users with more than 256M memory can use this setting. The name of this setting is [Disable Paging Management]. Changing its value from [0] to [1] can disable memory page scheduling.
⑵ Improve the system cache: change the key value of [large system cache] from [0] to [1], and Windows XP will allocate all system memory except 4M to the file system cache, which means that the XP kernel can run in the memory, which greatly improves the system speed. The remaining 4M memory is used for disk cache, and XP will allocate more if necessary under certain conditions. Generally speaking, this optimization will improve the system performance, but it may also reduce the performance of some applications. There is more than 256M of memory to activate the large system cache.
12. Prioritize IRQ interrupt requests: IRQ interrupt numbers are set for the main components of the computer. Optimization can be achieved by modifying the priority of IRQ requests. The main optimization object is the system /CMOS real-time clock, and the performance is improved through the motherboard. First, determine which component needs higher performance and find the hardware IRQ interrupt number. Open the system properties, select the Hardware tab, click the Device Manager button, right-click the component whose IRQ number you want to check, select Properties and click the Resources tab. You can see the IRQ interrupt number used by the device. Write down the interrupt number, run the registry editor, expand HKEY _ local _ machine \ system \ currentcontrolset \ control \ priority control, create a name [IRQ # priority] ("#" is the specific IRQ interrupt number), and set its value to [1]. If the IRQ interrupt number of the system CMOS real-time clock is 8, the name of the value to be established is [IRQ8Priority]. After restarting, you will find that the performance of the newly optimized components has improved. This method is strongly recommended to optimize the CMOS real-time clock of the system. You can also increase the priority of multiple IRQ interrupt numbers, but the effect is not very good, which may cause system instability. To undo this optimization setting, just delete the registry key value you just created.
13. close the debugger. Dr. Watson: start-run-regedit opens the book table, finds HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ currentversion \ AE debug, changes the numeric data of the string value [Auto] to [0], presses F5 to refresh to make the setting effective, and then cancels its operation.
14, turn off the special effects in the system properties, which is a good way to speed up. Start → Control Panel → System → Advanced → Performance → Settings → In the visual effect, adjust the settings to the best performance → OK. In this way, the desktop will be very similar to win2000. If you like the blue windows of XP, you can check "Use visual styles on windows and buttons".
15, using Windows commadner+Winrar to manage files, Win XP's ZIP support is even worse than chicken ribs, because no matter whether it is necessary or not, the boot system will open a zip support, which reduces the already scarce system resources by one point. Start → run, type "regsvr32/u zipfldr.dll" and press enter to confirm. The sign of success is that a prompt window appears: DLL is in zipfldr.dll.
16. Turn on DMA: select the IDE ATA/ATAPI controller in the device manager, enter the advanced settings of the main/auxiliary IDE channel, and set all the transmission modes to use DMA (if any), and the system will automatically turn on DMA support (also set it to support DMA in the BIOS first).
Ways to save hard disk space:
1. Delete system backup file: Start → Run → sfc.exe/purgecache..
2. Delete the driver.cab driver backup file in the %windows%\driver cache\i386 directory.
3. If you are not used to reading Help, you can delete all the contents in the %windows%\help directory.
4. After patching (or upgrading), you will find that %windows%\ still has many files like $ TERM $ TERM $NtUninstall, and delete them all.
5. Put the virtual memory file pagefile.sys on a disk other than the system disk: control panel → system → performance → advanced → virtual memory → change. Please note that the Settings will take effect.
6. Uninstall the uncommon components: use Notepad to modify %windows%\inf\sysoc.inf, use the find/replace function, enter, hide in the find box, and replace all with ",". In this way, all the "hiding" is removed. After saving the disk, run "Add-Remove Program", and you will see many more options in "Add/Remove Windows Components". Delete games, code watches and other unused things.
7. Delete the input method that is not used under \windows\ime. Reinstall your own input method.
9. Turn off system restore, which will take up a lot of hard disk space. Right-click my computer on the desktop, select Properties, find System Restore, and then select Turn off System Restore on all drives.
10, turn off hibernation: this function takes up four or five hundred megabytes of hard disk space. Closing method: Right-click the blank of the desktop and press Properties to open the display properties window → Select the screen saver page → Press the power (O) key in the lower right corner to open the power options properties window → Select the hibernation page → Remove the check before enabling hibernation (H) and confirm all the way.
1 1. Move the temporary folder of the system and users out of the system disk: right-click my computer on the desktop, select Properties, select the Advanced tab in the pop-up system properties dialog box, and then click the environment variable button to pop up the environment variable dialog box, and select under XXX user variables. In the pop-up Edit User Variables dialog box, change the variable value from the default "C:/documents and setting/user name/Temp" to "X:/eee/temp" (X stands for the drive letter of the disk to be moved, and YYY stands for the parent folder of "temp"), then click OK to return to the Environment Variables dialog box, and then select "Environment Variables". Similarly, change the values of variables "Temp" and "Tmp" under "system variables" to "X:/YYY/Temp", and then make sure to return to the desktop and restart the machine all the way before the changes take effect. It is recommended to delete files in this folder regularly.
12. Move the temporary Internet files folder out of the system disk: Control Panel →Internet Options → General → Temporary Internet Files → Settings → Move the folder. It is recommended to delete files in this folder regularly.
Nine ways to edit this paragraph to make the computer start faster
Nine tricks to make the computer start faster
It is the common wish of every computer fan that the computer starts too slowly, and it is everyone's wish to start the computer faster. In the process of using the computer, I summed up the "eight formulas" to speed up the computer startup and shared them with you.
First, the optimization of bios settings
On the homepage of bios settings, we enter the "Advanced bios Function" option, move the cursor to the "First Boot Device" option, and press "pageup" and "pagedown" to select. The default value is "floppy", which means that the system will first read the startup information from the floppy drive when starting, which will shorten the startup time of the machine and shorten the life of the floppy drive. So we have to choose "hdd-0" to boot directly from the hard disk, which takes a few seconds to boot. In addition, it is recommended to select "Disabled" for "above 1 bmmemorytest" in bios settings, and select "Enabled" for "quickpoweronselftest".
The settings in "Advanced Chipset Features" have a great influence on the acceleration of the machine, please pay more attention. Change "bank 0/ 1 dram timing" from "8ns/ 10ns" to "fast" or "turbo". "Turbo" is faster than "Fast", but it is unstable. It is suggested to choose "Fast". If the memory quality is good, you can try "Turbo Frequency", and if it is unstable, you can change it back to "Fast".
For memory chips with good memory quality, it is suggested to set it to "2" in the "sdram cas latency" option, which can speed up the speed.
Newer motherboards all support agp4x. If your graphics card also supports agp4x, activate it in "agp-4xmode", that is, select "enabled", which can give full play to the capabilities of the graphics card and speed up the system startup.
Second, start dma mode to improve the speed of hard disk.
The highest transmission rates of hard disks using udma/33, 66 and 100 technologies are 33mb/s, 66mb/s and 100mb/s respectively, which is 3 ~ 6 times of the ide hard disk transmission rate in theory (in pio mode4 mode here, the transmission rate is16.6mb/).
The specific method is as follows: open the control panel → System → Device Manager window, expand the disk drive branch, double-click the udma hard disk icon, enter the Properties → Settings → option, tick in front of dma, then press OK to close all dialog boxes and restart the computer.
Third, remove the boot sign of windows (only valid for windows98).
First, you should open the Start → Settings → Folder option, and check "Show all files" in the "Advanced Settings" list box of the "View" tab. Then open drive C, find the file msdos.sys, cancel its "read-only" attribute, open it, and add a line under the "options" paragraph: logo=0, so that the boot mode running windows will not be loaded, and the boot time can be shortened by 3 seconds.
Fourth, optimize the "starting" group.
Novices love to try all kinds of software and delete it quickly, but often for some inexplicable reasons, these software will still stay in the "startup" project (especially when using some D-version software), and windows will waste a lot of time when starting. To solve this problem, it is actually very simple. You can open Start → Run, select and enter msconfig in the open bar of the dialog box that appears, then click OK to bring up the system configuration utility, click the Start tab, and remove the √ in front of the program that does not need to load the startup group. In this way, the startup time can be shortened by at least 10 second.
5. Organize and optimize the registration form.
After windows is turned on, the system should read the relevant information in the registry and temporarily store it in ram. Most of the time windows is open is spent on this. Therefore, it is necessary to sort out and optimize the registry. For the optimization of the registry, software such as windows Optimizer can be used. With windows Optimizer, click "Clean up registration information" → "Scan", and the software will automatically clean up the garbage in the registry for you. After scanning, a menu will pop up for you to choose whether to back up the registry. It is recommended to select backup, and click "Clear" after backup. Seven, expand the virtual memory capacity.
If your hard disk is large enough, turn on the system in the control panel and turn on the virtual memory in the performance options. Select the second option: users set their own virtual memory settings, point to a hard disk that is rarely used, and set the maximum and minimum values to a fixed value, which is about twice the size of physical memory. In this way, when using hard disk in virtual memory, you don't have to accommodate the size difference, but use fixed space as virtual memory to speed up access. It is best to set the virtual memory after "disk defragmentation", so that the virtual memory can not be divided into continuous space without fragmented files and can play a better role.
Eight, get rid of fancy settings such as "wallpaper" and "screen saver".
Needless to say, these settings occupy system resources and seriously affect the startup order of windows. The way to get rid of them is to right-click in the blank space of the desktop, select properties in the pop-up menu, select the labels of background and screensaver in the pop-up dialog box respectively, and set the wallpaper and screensaver to none.
Nine, try to reduce the startup items.
Many softwares are started by default, just disable them.
