1. "Windows + R" to open "Run", enter "Regedit" to open "Registry".

Addition and deletion of some special commands:

1. Resource Manager.

In Windows systems, the "Explorer" command is available in the right-click menu of ordinary folders, drives, recycle bins, etc. If you only want to keep this command in the drive, you can first select "HKEY_CLASSES_ROOT" \folder\shell" primary key, delete the explore subkey, and then create a new "explore\command" subkey in the "HKEY_CLASSES_ROOT\drive\shell" primary key, making the commmand key value "C:\WINDOWS\Explorer.exe/e, /idlist,%I,%L".

2. Empty the Recycle Bin.

First find out the source of the "empty recycle bin" command, and then copy it to "HKEY_CLASSES_ROOT\＊". We open "HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\shellex\ContextMenuHandlers" and we can find a subkey named "{645FF040-5081-101B-9F08-00AA002F954E}" under it. Create a new subkey named "{645FF040-5081-101B-9F08-00AA002F954E}" under "HKEY_CLASSES\ROOT\*\shellex\ContextMenuHandlers".

3. Add and delete subcommands of the new command.

Open "HKEY_CLASSES\ROOT\.htm", add a primary key shellnew, and then create a new string value NullFile. The key value is empty. Right-click on the desktop and the "Delete" option will appear.
