First, make sure to back up your registry in case something gets messed up. Now open the registry editor by going to Start, then Run and then typing in REGEDIT.
Edit right click menu for files
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers\
All the folders listed under ContextMenuHandlers are applications that show up when you right click on a file in Windows. You can either delete the folder to remove the option or simply disable the folder, which is better in case you want to bring it back later on.
You can disable an application by clicking on the folder in the left pane and then right-clicking on the key value in the right pane and choosing “Modify“.
All you need to do is add a minus (-) in front of the key value.
Edit right click menu for Folders
You can follow the same steps as shown above for folders also, it’s just a different registry path. In order to edit the menu options for right clicking on folders, go here:
HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers\
Edit right click menu for specific file
For example, edit the popup menu for html files, go here:
HKEY_CLASSES_ROOT\htmlfile\shellex\
That’s it, easy??
