●Set whether the screen saver uses a password:
Open the HKEY_CURRENT_USER\Control Panel subkey branch, create a new DWORD value in the window on the right, name it "ScreenSaverSecur", and set its value to 1. In this way, when the screen saver is over and back to the original interface, it will be prompted to enter a password. This is very beneficial for preventing others from using your computer and protecting the computer security when people walk away.
●Delete the redundant color scheme:
Open the HKEY_CURRENT_USER\Control Panel\Appearance\Schemes sub-key branch. At this time, the existing color schemes in Windows XP will appear on the right side of the pane. If you don't think you need so many and some of them are not available at all, you can delete all the schemes you think you don't need, and only the schemes you need to use are retained.
●Set the background used by the active desktop:
Open the HKEY_CURRENT_USER\Control Panel subkey branch, create a new string value in the window on the right, name it "ConvertedWallpaper", and set its key value to the background file (must be full path), such as D:\pictures\landscape\best\.
●Modify the refresh frequency of the monitor:
Open the HKEY_CURRENT_CONFIG\Display\Settings subkey branch, and modify the key value of the key item "RefreshRate" in the window on the right to 85, so that the refresh frequency of the monitor will be set to 85Hz.
●Prohibit icons on the desktop prompt message:
Open HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced subkey branch, change the item value of the ShowInfoTip key value item to 0 in the window on the right, and refresh the desktop and take effect immediately. This way, when you move the familiar table to a "My Computer", the prompt message "Show drives and hardware connected to this computer" will no longer appear.
● Block the "Nearest Computer" icon in "Online Neighbors":
This is mainly for security reasons. Open HKEY_CURRENT_USER \Software\Microsoft \Windows\CurrentVersion \Policies\Explorer subkey branch, create a new DWORD value in the window on the right, name it "NoNetConnectDisconnect", and set its value to 1.
●Hide a server in "Online Neighbors":
Open HKEY_LOCAL_MACHINE\System\Current ControlSet\Services\LanmanServer\Parameters subkey branch, create a new DWORD value in the window on the right, name it "Hidden". If it already exists, you don't have to create it yourself. Set its value to 1.
●Hide the "Enterprise Network" icon in "Online Neighbors":
Open HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer subkey branch, create a new DWORD value in the window on the right, name it "NoEntireNetwork", and set its value to 1.
●Clean off the remaining information after accessing "Online Neighbors":
Users in Windows XP LAN access "Online Neighbors" and leave some information in their registry, including the accessed host name, application name, etc. This information is basically useless and can be cleaned up. Open the HKEY_CURRENT_USER\Network\Recent subkey branch, and delete all the key-value item data under the primary key Recent.
●Show file extension:
In Windows XP, the default format of a file is to only display the file name, not the extension, so that users do not know what type of the file is. Sometimes it is inconvenient. By modifying the registry, the extension of the file can also be displayed, which looks clear at a glance. Open HKEY_CURRENT_USER\ Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced subkey branch, and then change the value of the key value item "HideFileExt" in the right window to 0 to display the file extension.
●Implement automatic refresh of "Explorer":
When the content in Explorer changes, press the F5 function key to refresh the content in the Explorer pane. If it is not refreshed, the content remains unchanged, and the refresh function can be automatically performed by modifying the registry. Open the HKEY_LOCAL_MACHINE\System\Current ControlSet\Control\Update subkey branch, change the value of "UpdateMode" to 00 in the window on the right, and restart takes effect.
●Preview BMP files in icon format in Explorer:
Is it more convenient to preview the picture? :) Open HKEY_CLASSES_ROOT\\DefaultIcon subkey branch and change the "default" key value name in the right window to "%1".
