When you right-click a blank space on your desktop or in File Explorer (not Quick access), you’ll see a context menu that includes New.
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 and removing the hyphen you added.
