Winxp System Optimization Guide

1. Cancel the waiting time before the disk scan When using Windows XP, if you encounter power failure, crash, etc., Windows XP will automatically scan the disk after restarting the computer. Before performing a disk scan, the system will give a 10-second countdown time for you to choose whether to skip the disk scan. If you don't want the countdown before the disk scan, you can cancel it. Select “Start/All Programs/Accessories/Command Prompt" in the Command Prompt window, press the key "CHKNTFS /T:0”", and press Enter to change the countdown time before the automatic disk scan to 0 seconds. .
2, delete the file backup into the "Windows\\System32\\dllcache" directory (the default is hidden directory), which stores about 360MB files, they are Windows XP system files backup, the folder can not be directly deleted, to At the command prompt, type “sfc.exe /purgecache” (with spaces before the slash) command to delete.
3, delete the driver backup Windows XP comes with a large number of hardware drivers, Windows\\DriverCache\\i386” directory, find the compressed file named "Driver.cab", delete it.

To delete it, go to “Control Panel\\Date, Time, Language and Regional Settings\\Region and Language Selection", select the "Language" tab, and remove the hook in front of the East Asian Language Installation File” , click "OK" and follow the prompts to remove the unwanted language options. After restarting, delete the “chtime”,“imju8_1”,“imk6_1” three folders (for traditional Chinese, Japanese, and Korean) directly in the “Windows\\ime” folder, which can release 85MB. Hard disk space
5, clear the system temporary files in the "\\Documents and Settings\\username\\LocalSettings\\Temp" directory (the default is hidden directory) stored in the temporary folder and discarded when the software installation goods run The documentation can free up hundreds of megabytes of hard drive space. This method can be used frequently.
6, Windows XP appears in the taskbar "fake death" phenomenon is more common, in addition to the installation of Microsoft's official patch to solve the problem, you can also prevent the taskbar from appearing by closing the advanced text service "fake death" Phenomenon (because the advanced text service is enabled, it consumes a lot of system resources, and may also conflict with some software, such as handwriting recognition, Chinese keyboard input, etc.), as follows:

7, every time you start Windows XP, the blue scroll bar will tirelessly walk a few laps. For those who pursue high efficiency, do you really want it to take a few laps? In fact, we can completely reduce its scrolling time to speed up the startup. To do this, open the Registry Editor, expand the HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Session Manager Memory Management PrefetchParameters branch, and find the EnablePrefetcher subkey in the middle window of the right window, and change its default value “3” to “ 1”. Next, right-click on the desktop and click "My Computer", select the "Properties" command, select the "Hardware" tab in the window that opens, click the "Device Manager" button . In the “Device Manager” window, expand ““IDE ATA/ATAP Controller”, double-click the “Secondary IDE Channel” option, and select ““Advanced” tab in the pop-up dialog box, at &ldquo In the device type & rdquo; in the device & rdquo;, the original & ldquo; automatic detection & rdquo; changed to & ldquo; no & rdquo;, & ldquo; OK & rdquo; and then exit. “ The main IDE channel & rdquo; modification method is consistent. Now restart your computer and see if your scroll bar scrolling time is reduced? Note: Friends who use the VIA chip motherboard must not modify the "VIA BUS MASTER IDE CONTROLLER" option. In addition, if you do not choose to create multiple different hardware profiles, or if you want to automatically load the default hardware profile during startup without displaying the list items, you can select “ seconds in the <quo;hardware profile selection” Enter in “0” Pressing the space bar when you need to select will display the list.
8. When Windows XP Network Neighborhood is used, the system will first search for its own shared directory and printers that can be used as network shares and related tasks in the scheduled tasks. The scheduled task is then displayed, which will directly affect the speed of the computer. If it is not necessary, it should be deleted. The specific steps are as follows: In the Registry Editor, find HKEY_LOCAL_MACHINE\\sofeware\\Microsoft\\Windows\\Current Version\\Explore\\RemoteComputer\\NameSpace, delete the {2227A280-3AEA-1069-A2DE08002B30309D} (printer) and {D6277990-4C6A- 11CF8D87- 00AA0060F5BF} (scheduled task), then restart the computer, when you visit the network neighborhood again, it is found that the running speed has increased.
9, when shutting down in Windows XP, the system will always send a message to the running program and the remote server, notify them that the system should be shut down, and wait for the response to receive the system before the system starts to shut down. If we want to speed up the boot, we can first set the time to automatically end the task. To do this, open the Registry Editor, expand the HKEY_CURRENT _ USER Control Panel Desktop branch, and locate the AutoEndTasks subkey, setting it to 1. Then set the "HungAppTimeout” subkey under the branch to “1000”, and <;WaitTOKillService” to “1000” (default is 5000). By resetting this way, the computer's shutdown speed can be significantly accelerated.
10, we all know that the professional version of Windows XP retains 20% of the bandwidth by default, in fact, this does not have much effect for our individual users. Instead of being idle, use it as follows: 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 “Disable” After this reset, you can release the reserved 20% of the bandwidth.
