Normally, when Windows XP connects to other computers, it will check all the scheduled tasks on the other machine. This check will let you wait for 30 seconds or more. The way to get rid of is to start, modify the registry run key, cancel those few things that are not commonly used, such as Windows Messenger. Enable Registry Manager: Start → Run → Regedit → find the key value of “HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\Current \\Version\\Run\\MSMSGS”/BACKGROUND, right click → delete, the world is quieter, by the way What cfmon is doing. 2, modify the registry to reduce pre-read, reduce the progress bar waiting time, the effect is that the progress bar runs into the login screen after a lap, start → run → regedit start the registry editor, find HKEY_LOCAL_MACHINESYSTEM\\ Current\\Control\\SetControl\\ Session anagerMemory\\ManagementPrefetchParameters, there is a key EnablePrefetcher to change its value to "1". In addition, friends who do not frequently change hardware can set the device type on the bus device to none in the system properties. 3. Turn off the special effects in the system properties, which is a simple and effective way to speed up. Click Start → Control Panel → System → Advanced → Performance → Settings → In Visual Effects, set to adjust for optimal performance → OK. This way the desktop will be very similar to win2000. I still like the blue window of XP, so I put a tick on "Use visual styles on windows and buttons", so that you can see the beautiful blue interface and speed up. . 4, I use Windows commadner + Winrar to manage files, Win XP's ZIP support is not as good as mine, because no matter what I need, the boot system will open a zip support, the system resources are less and less. Points, click Start → Run, type: "regsvr32 /u zipfldr.dll" in the middle of the double quotes, and then press Enter to confirm, the success flag is a prompt window, the content is roughly: Dll UnrgisterServer in zipfldr.dll success. 5, it is said that XP's system service Qos, this scheduling has to occupy a certain network bandwidth, such as a hairless person I can not stand, remove the method is: Start menu → Run → type gpedit.msc, "Group Policy" appears Window, expand "Administrative Templates" → "Network", expand "QoS Packet Scheduler", right-click "Restrict Reservable Bandwidth" in the right window, and "Limit Retainable Bandwidth" in "Settings" in the properties. Select "Disabled" and confirm. After the above modification is completed and applied, the user can see the "QoS Packet Scheduler" in the general attribute tab column in the properties dialog box of the network connection. The modification is successful. Otherwise, the modification fails. By the way, the QoS protocol in the network attribute is also killed (uninstalled). 6. Quickly browse the local area network sharing Under normal circumstances, Windows XP will check all the scheduled tasks on the other machine when connecting to other computers. This check will let you wait for 30 seconds or more. The method to remove is Start → Run → Regedit → find HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\Current \\Version\\Explorer\\Remote\\Computer\\Name\\Space in the registry. Under this key value, there will be a D6277990-4C6A-11CF-8D87-00AA0060F5BF{} button, after deleting it, restart the computer, Windows XP will not check the scheduled task, hoho~~~, the speed is obviously improved La! 7, turn off the debugger Dr. Watson I seem to have never used this thing since the win95 era, you can cancel this: open the album, find the HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\Current\\Version\\AeDebug subkey branch, Double-click the Auto key name under it, change its "Value Data" to 0, and finally press F5 to refresh the settings, thus canceling its operation. Following this idea, we can cancel all options with debugging functions, such as memory.dmp that appears when the screen is blue, in "My Computer → Properties → Advanced → Settings → Write Debug Information → Select None" and so on.
