. You have been using Windows XP for a long time, and you are already very familiar with the Windows XP operating system! Below, the author will share some of the experience accumulated in the process of using Windows XP operating system, so that everyone can master the use of XP more skillfully, and better enjoy the powerful functions brought by XP system. 1. Recover corrupted WinXP system files If Windows XP system files are corrupted by viruses or other reasons, we can recover those corrupted files from the Windows XP installation disk. Specific method: Search for the corrupted file in the installation disk of WindowsXP. It should be noted that the last character of the file name is replaced by the bottom line "_". For example, if you want to search for "Notepad.exe", you need to use "Notepad." Ex_" to search. Once you have found it, open the command line mode (enter "cmd" in "Run") and enter: "Full path to the full path object file of the EXPAND source file". For example: EXPANDD: SETUPNOTEPAD.EX_C: WindowsNOTEPAD.EXE. One thing to note is that if there are spaces in the path, you need to include the path in double quotes (quotation marks). Finding is of course the best, but sometimes we can't find the files we need when searching on the Windows XP disk. One reason for this is that the file you are looking for is in the "CAB" file. Since Windows XP treats "CAB" as a folder, for Windows XP, just drag and drop the "CAB" file to the appropriate directory. 2, refused to "group similar taskbar" Although the Windows XP "group similar taskbar button" setting can make your taskbar less open window, keep it clean, but for some work that needs to open multiple windows of the same kind is very inconvenient. If you use QQ communication software to chat with people online, if there are more than two friends talking to you at the same time, you will immediately feel the inconvenience caused by XP default settings every time you want to switch conversation objects, You must first click on the group, then select the friends you want to talk in the pop-up menu, and each friend displays the same icon in the group. When there are many conversation objects, you may have to click one by one to see exactly Whoever replied, waiting for your reaction, and choosing the wrong one, has to choose from the group, it is very troublesome. Obviously, this is not as good as opening a few windows, and clicking on each small window in the taskbar can start chatting. Change method: Click “Start → Control Panel → Appearance and Theme → Taskbar and ‘Start Menu”. In the pop-up window, remove the hook in front of the “Group similar taskbar button” option. 3. Uninstalling the useless dynamic link through the registry The resource manager often leaves useless dynamic links in memory. To eliminate this phenomenon, you can open the registry editor and set the key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows CurrentVersionEXPlorerAlwaysUnloadDLL=DWORD:1 Set to 0 and this feature will be turned off. Note: In order for the settings to take effect, you will need to restart your computer. 4, clear the prefetch file in the prefetch folder When WinXP is used for a period of time, the files in the pre-read folder will become very large, there will be dead chain files, which will slow down the system time. Recommendation: Delete these files on a regular basis. (Windowsprefetch) 5, WindowsXP weight loss method The following method is my current WinXP weight loss method, after use, I feel safer, the effect is obvious, at least can reduce the space of 300m. Note: It is not recommended for beginners. Remove the driver backup: Driver.cab file (73MB) in the WindowsDrivercachei386 directory, but we must insert the Windows installation CD each time we install new hardware. Delete system file backup (usually not used): Run the command line sfc/purgecache to delete the alternate dll file: as long as you copy the installation file or have an installation CD, you can do so. Files under Windowssystem32dllcache (minus 200 - 300mb). 6, understand WinXP startup time Although the startup speed of WindowsXP has made us satisfied, but Microsoft still provides us with a gadget to understand the specific startup time of WindowsXP startup, and to check the CPU usage. , DiskI/O, etc., because the tool is displayed graphically, so it is clear at a glance. This gadget is useful if you can upload it if you need it. 7, recovery EXE file associated EXE file association error is very troublesome, because the occurrence of this situation is mostly caused by the virus, and the main file of the anti-virus software is EXE file, since the EXE file association error, how can run anti-virus Software? Fortunately, XP provides a command line tool in safe mode for us to use, you can use the command line tool to solve this problem. In safe mode, type: assoc.exe=exefile, and “.exe=exefile” will appear on the screen. Now close the command prompt window, press Ctrl+Alt+Del to bring up the “Windows Security” window, press the “Shutdown” button and select the “Restart” option. After starting Windows in normal mode, all EXE files will be normal. Run it! 8, let WinXP automatically update When Windows has an update, the automatic update system will prompt you to upgrade Windows, of course, this feature will have a real effect after the Internet. One thing to be sure is that in order to achieve automatic updates, the system must collect the user's computer information, and then send it to the Microsoft site, through feedback to decide whether to upgrade. This setting is also in the "System Properties" window. Switch to the "Automatic Updates" tab. You can see that there are three choices here. The last one is "Close Auto Update", so the system will not prompt you to automatically update. If you are not using the genuine Windows XP operating system, I suggest you turn off this feature, because he may let you upgrade the system to Windows XP SP2 without knowing it, which will cause system instability.
