'''Reg_SZ''' | |||
* Standard string | |||
'''Reg_EXPAND_SZ''' | |||
* Allows system variables like in <code>"'''%SystemRoot'''"\Notepad.exe %1</code> | |||

UserChoice | |||
If you set a default program for a file type, "UserChoice" will be created and point to that program and its (shell) context menu. | |||
Better do backup and restore it when your own changes get uninstalled. | |||

===Sub Menus=== | |||
For sub menus you need a '''SubCommands''' value. The commands may contain points in their name and are separated by semicolons. | |||
shell | |||
| | |||
+-- MenuName | |||
| | |||
+-- Name: Icon, Type: REG_SZ, Data: "PATH_to_exe" | |||
+-- Name: MUIVerb, Type: REG_SZ, Data: displayed name | |||
+-- Name: '''SubCommands''', Type: REG_SZ, Data: MenuName.commandName1;MenuName.commandName2;MenuName.commandNameN | |||
Individual commands are then stored at | |||
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell | |||
MenuName.commandName1 | |||
| | |||
+-- command | |||
MenuName.commandName2 | |||
