Computer response slow

Computer shop news [How can make the slow response computer faster] 1, consider the situation of the virus: restart the computer F8 key to select the safe mode to enter the safe mode - open your anti-virus software full anti-virus - - This way the anti-virus kill is relatively clean and thorough; 2, consider the hardware problem: open my computer - select D drive - right click on the property - tools - defragmentation - start finishing - analysis (analysis results need to be organized) - defragmentation You can relocate the disk space; 3. There are too many startup programs, you can remove some extraneous plug-ins and programs. In the lower right corner of the machine, you can choose to quit some useless programs. The more you open, the more you can run. If you have tried all of the above, you can reinstall the system. If necessary, you can reformat the partition (save important things). Do your usual anti-virus, scan for the poison, and go to my pocket. Look, optimize the background service. Or use software optimization like the optimization master. In the process of using XP, the system running speed will become slower and slower over time. Some friends may think of reinstalling the system, but after reinstalling, so many applications should be reinstalled. How to What is the speed of XP upgrade without installing the system? As long as you operate in the following nine aspects, I believe that your XP will run again at high speed. 1. Speed ​​up the power of the switch When you shut down in Windows XP, the system will send a message to the running program and the remote server, telling them that the system should be shut down, and wait for the response to start the system. To speed up the boot process, you can first set the auto-end task. First find HKEY_CURRENT_USERControl PanelDesktop, set the AutoEndTasks key to 1; then there is a "HungAppTimeout" under the branch, and change its value to "4000" (or less). ), the default is 50000; finally find HKEY_LOCAL_MACHINESystemCurrentControlSetControl, also set WaitToKillServiceTimeout to “4000”; By setting the shutdown speed significantly faster. 2, improve broadband speed Professional version of Windows XP by default retains 20% of the bandwidth, in fact, this is not useful for our individual users. In particular, let it be used as well as it is fully utilized. Enter gpedit.msc in "Start →Run" to open the Group Policy Editor. Find & ldquo; Computer Configuration & Rarr; Management Template & Rarr; Network & Rarr; QoS Packet Scheduler & rdquo;, select the right side of the "restricted bandwidth can be reserved", select "properties" & rdquo; open the limit can retain the bandwidth properties dialog box, select “Enable ”, and change the original “20” to “0”, thus releasing the reserved bandwidth. 3. Optimize Network Neighborhoods When Windows XP Network Neighborhood is used, the system will search for its own shared directory and printers that can be used as network shares and scheduled tasks related to the network in the scheduled tasks, and then display them, so the speed will obviously be much slower. These features can be removed if they are not very useful for us. Find HKEY_LOCAL_MACHINEsofewareMicrosoftWindowsCurrent VersionExploreRemoteComputerNameSpace in the Registry Editor, delete the (printer) and {D6277990-4C6A-11CF8D87- 00AA0060F5BF} (scheduled tasks), restart the computer, visit Network Neighborhood again, you will find a lot faster. 4, speed up the startup speed To speed up the startup speed of Windows XP. You can do this by modifying the registry. In the Registry Editor, find HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetchParameters, find the EnablePrefetcher primary key on the right, and change its default value of 3 to 1, so that the scroll bar scroll time will be reduced; Stop responding to the program Sometimes, XP will prompt you that a certain program stops responding, which is annoying. We can let it shut itself down by modifying the registry. In HKEY_CURRENT_USERControl PanelDesktop, change the value of the character whose value is AutoEndTasks to 1, and then re-logout or Start it. 6, speed up the menu display speed In order to speed up the display speed of the menu, we can set the following methods: we can find the "MenuShowDelay" key under HKEY_CURRENT_USERControl PanelDesktop, change its value to "ldquo;0”" can speed up the menu display The effect of speed. 7, clear the DLL file not used in memory In the registry HKKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersion, add an item AlwaysUnloadDLL in the Explorer, the default value is set to 1. Note: If the default value is set to 0, this function is disabled. 8, speed up the read-ahead ability to improve the boot speed Windows XP read-ahead settings can increase the system speed and speed up the boot. Modify the following method to further improve the efficiency of the CPU: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSessionManagerMemoryManagement], ?refetchParameters right window, change the value data of EnablePrefetcher as follows, if you use the PIII 800MHz CPU or above recommended to change the value data to 4 or 5, otherwise it is recommended to keep The numeric data is the default value of 3. 9, reduce the load-time loading project Many applications will be added to the system startup group when installing, each time the system will automatically run, which not only extends the startup time, but also the system resources have been consumed after the startup! Start “System Configuration Utility", listed in the "Startup" item, the project and source loaded at system startup, carefully check if you need it to load automatically, otherwise clear the check box before the project, load The fewer the projects, the faster the startup will naturally be. This item needs to be restarted to take effect.
