Let’s take a look at how to remove New from the context menu in Windows 10.
Go to: HKEY_CLASSES_ROOT > Directory > Background > shellex > ContextMenuHandlers > New.
Double-click the Default in the right pane.
Add – (hyphen) to the beginning of the Value data field.
Then click OK.
So that’s it.
You can get back New by following the above steps but by removing the hyphen that you added.
