Add Any Application To Right Click Menu of Folder

I will add cmd to right click menu of folders here. You can add any other application that you use most frequently using this method. 

1. First of all open registry editor. To open registry editor press Ctrl+R. Now type regedit in RUN window and press enter.
2. Now go to HKEY_LOCAL_MACHINE -> SOFTWARE -> Classes -> Folder -> shell.
3. Right click on shell and make a new Key. You can name it anything. I will name it as cmd.
4. Now right click on newly created key (cmd) and create a new key value again and name it as command.
5. Under command key value craete a new String Value by right clicking anywhere under command key.
6. Double click on new String Value and change its Value data. If you want to make shortcut to cmd then its Value data will be – C:\Windows\System32\cmd.exe 
7. Close the registry editor. Now right click on any folder to see the changes.
