Computer acceleration problem

You can optimize the processing (WinXP) according to the following methods to speed up the system operation: 1. Use anti-virus software to kill virus and ensure that the system is virus-free. 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 \, change the numerical data of string value [hungaptimeout] to [0], and change the numerical data of 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 add it. (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. When starting the computer, run the Defrag program to start the registry editor, find HKEY _ local _ machine \ software \ Microsoft \ dfrg \ bootpoptimize function, and set the string value [Enable] as: [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 paging execution in memory. 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: Open the book table, find HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ Current Version \ AE Debug, change the numerical data of the string value [Auto] to [0], press F5 to refresh the setting to take effect, and then cancel 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 the system backup file: Start → Run → sfc.exe/Purge Cache. 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%\ has many files similar to $ ntuninstallq311889 $,all of which have been deleted. 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 methods that are 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 at regular intervals. 12 and 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.

[Edit this paragraph] Eight tricks to make the computer start faster

Eight tricks to make the computer start faster think that it is a common problem for every computer fan to start the computer too slowly. It is everyone's common wish to make the computer start faster. In the process of using the computer, I summed up the "eight styles" to speed up the computer startup and shared them with you. 1.bios optimization is set on the first page 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 maximum transmission rate of the hard disk using UDMA/33,66, 100 technology is 33mb/s, 66mb/s,1000 MB/s, which is theoretically an ide hard disk (here refers to pio mode4 mode, and its transmission rate is 16.6mb/s). 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. 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. Six, regular maintenance system. If there are too many games, too many applications and too many old materials in the system, your computer will be slower and slower, and the boot time will be longer and longer. So it's best to do a comprehensive maintenance of the computer every once in a while. Click Start → Programs → Accessories → System Tools → Maintenance Wizard, and then click OK to comprehensively maintain the computer and keep it in the best condition. For the hard disk, it is best to do "defragmentation" every two weeks, which will obviously speed up the startup of the program. Just click System Tools → Disk Defragmenter. Pay attention to the disk where the system is located when defragmenting the disk, so as to really speed up the startup sequence of windows. 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.

[Edit this paragraph] Skills to improve network speed

1. Delete irrelevant options.

In Windows XP, double-click the folder option in Control Panel, click the View tab, and then scroll the mouse pointer to the bottom of the window. You can see that there is an item "automatically search network folders and printers", which is selected by default and removed. In this way, when we print, Windows XP will not take the initiative to find the printer and install the driver on the local area network, in order to prevent confidential documents from being inadvertently typed into printers of other departments but not found by itself. At the same time, after this item is removed, when we access the local area network computer through "Online Neighborhood", it will not automatically find the * * * shared folder on it, which will speed up some.

2. Adjust the network card to full speed.

Press Win+Pause/Break, click the hardware tab, then click the device manager to open the device manager, double-click the corresponding network card under the network card, click the advanced tab in the opened window, select the link speed/duplex mode, and then select 100 full mode under it. Of course, if you are using a wireless network, just turn it to the highest speed. This is my wireless network card D-Link Air Plus XtremEG+DWL-G650+ Wireless Cardbus Adapter # 2, and I set its desired basic speed to the highest 54Mbps.

3. Get rid of irrelevant agreements

Open the network connection window, right-click the local connection, select Properties, and then delete unnecessary protocols in the opened window. If Windows 98 is used, TCP/IP-Dial adapter, Microsoft friendly login, Microsoft virtual private network adapter and IPX/SPX compatible protocol can all be removed, because these components are rarely used, and if selected, it will affect the normal Internet access and browsing of workstations.

4. Set an empty password to log in.

If you don't save sensitive data on the computer, just put some public resources, you can set an empty password to log in. In this way, users can enter directly without providing a password, which can save time and make it more convenient to tell others the password. Press Win+R, enter gpedit.msc, open the group policy editor, find the computer configuration → "Windows Settings → Security Settings → Local Policy → Security Options", and then double-click the account: local accounts with empty passwords can only log in to the console, and set it as disabled in the opened window. Next, open the Explorer on this machine, select Tools → Folder Options, click the View tab, and then uncheck "Delete Simple Files * * * Enjoy (Recommended)".

5. Log on to the LAN automatically.

If you need to access a * * * folder every day, you don't need to double-click "My Neighbors" step by step, then find the server, double-click and enter the user name and password before accessing. For example, if you want to visit a computer named server, the user name is User and the password is 8888, you only need to write a bat file, and enter the following statement in it: net use server IPC $ "8888"/user: "user", and then drag the bat file to the "Start → Program → Start" group, so that the system will use User as the user name, 8888. If you are using Windows XP, you can enter your user name and password at the first boot, and then select the "Remember my password" option, so you won't ask us for the password next time.

6. Cancel the firewall

If the firewall is enabled in Windows XP and * * * enjoys the drive, then it is possible that others will not be able to browse the * * * shared drive in my network neighborhood. At this point, you can right-click the Local Area Connection, select Properties, click the Advanced tab, click the Configure button, and select the "Close (Not Recommended)" item in the window that opens. Because our LAN computer itself is connected to the router, we can consider setting a firewall on it. In this way, the machines in the LAN will not be attacked by the outside world, but the access of the machines in the LAN will be faster.

7. Multi-system fast mutual access

If you find that Windows 2000 machine is particularly slow to access 98 machine, you can press Win+R on 2000 machine, enter "regedt32", find [HKEY _ local _ machinesoftwarewindows current version exploreremote computernamespace] in the registry editor, find and delete the KEY under this branch, and then double-click 98 colleague's machine.

8. Quickly back up/update data

If you often need to back up data to a file server in the LAN, do you want to select the file on the local hard disk and then switch to the file server to paste it? This is too much trouble. In fact, as long as we know the name of the file server (such as file_bck) and its user name (such as user) and password (such as 123456), we can run a batch file now. The contents of this batch file are as follows: set source = d: workset dest = file _ bckbackupnetusefile _ bcipc $ "1234"/user: "user" xcopy% source%% dest%/e/v/r/y/ Save z as batchcopy.bat, and then double-click this bat file to back up all files of d:work to file _ bckbackup.

9. Quickly map drive letters

Open the root folder of * * * enjoyment machine, such as homepc, then select the corresponding folder, and right-click the "Map Network Drive" command to map the folder to a drive letter immediately. If we directly choose Tools → Map Network Drive, we need to choose the mapping path.

[Edit this paragraph] Seven ways to speed up computer operation

1. Delete the LJ file left over from the Internet, simply clean the disk, open IE browser, select Tools/"Internet Options" in the menu bar, select the General tab in the dialog box that appears, and click the Delete File button in the Internet Options area to delete the LJ file left over from the Internet. When cleaning up LJ files, you can use some optimization tools, such as "windows Optimizer" and "Super Rabbit Magic Settings" to clean up LJ files. For the above two softwares, there is an introduction later. For basic system cleaning, you can select Start/Accessories/System Tools/Disk Cleaning in turn on the desktop, start the disk cleaning tool, select the drive letter to be cleaned, check the cleaning option, and click OK to start cleaning. It should be emphasized that there is not much space to clean up here, but the significance is that these small files will affect the performance and efficiency of the system because they are too fragmented. 2, turn off all visual effects XP default visual effects are beautiful, but it also consumes system resources. Right-click the "My Computer" icon, select the "Performance" area of the "Properties"/"Advanced" tab, click the "Advanced" button, and select "Adjust to Best Performance" in the "Visual Effects" tab to restore the system style before 2000. If you want to study XP style and optimize it, there is a way for you to have your cake and eat it: in the visual effects tab, select custom, and in the column below, just check three options: use visual styles on windows and buttons, use shadows for icon labels on the desktop, and use common tasks in folders. 3. Restore the classic start menu XP's new start menu. Every time you open it, you always keep searching for the recently opened program shortcuts. In order to improve the speed, you can change it to the "start" menu similar to 98. Right-click the blank space of the taskbar and select the "Properties" command to open the "Taskbar and [Start] Menu Properties" setting window. Go to the [Start] menu tab and select the [Classic] menu. 4. In XP system, the automatic playback function of CD is blocked. When the user puts in a CD with automatic playback function, the system will automatically start running the CD content; Even if it is an ordinary CD, the system will try to call the wizard to let you choose a way to run the CD. If you don't want the system to interrupt your current job in this way, turn it off. Enter gpeidt.msc in Start/Run to start the group policy, and then select Computer Configuration/Management Template/System/Play Off, set it to Enable, and play automatically for all drives. If autoplay is enabled, simply set the property to Not Configured. Turning off the "autoplay" function is not only worry-free, but also safety is the main thing. 5. Disable the error reporting function. The function of "Error Reporting" is to automatically report software errors to Microsoft when there are errors in the operating system, which is generally of little use and can be turned off. Right-click My Computer, select Error Reporting in the Properties/Advanced tab, select Disable Error Reporting, and then select Notify me when a serious error occurs. This function depends on the situation. The advantage of the "Error Report" function is that once a system error occurs and the user selects "Send", Microsoft will record the error. When many users send the same problem, Microsoft will take measures to solve the problem. After the user sends the same error report, IE will automatically pop up the solution to this error. 6. Turn off redundant services Many services that are turned on by default under XP can be turned off for stand-alone users. Click Start/Control Panel, and then double-click Manage Devices/Services. In the window that appears, the existing service components of the system will be automatically listed, and some components will be closed appropriately according to the actual situation. " Windows Optimizer provides automatic optimization of system services, which is very suitable for lazy people. 7, improve the network card transmission rate XP By default, the network card transmission rate is adaptive. Every time the network card starts to work, you need to repeatedly check the network card transmission rate and manually specify a fixed transmission rate, which can improve the network speed (provided that you know what your real transmission rate is). Right-click my computer, select the Device Manager button in the Properties/Hardware tab, select the network card device under the network card tree, right-click the Properties command to open the property setting window, and you will see various property settings about the network card hardware in the Advanced tab. Locate and set the Link Speed/Duplex Mode parameter.
