Have you noticed that some applications like Antivirus, WinZip, and others, add
some items to the context menu when you right-click on a file or folder?
Apart from above, these software install shell extensions to add applications
in the right-click context menu. If you delete the appropriate shell extension
in the registry, you won’t get these additional menu items.
I am trying to remove the Open Presentation and Open Drawing items from the
Right Click “new” menu.
Note: Make sure you have made a proper backup
of your Registry. In case you have mistakenly removed the wrong folder, the
backup will come handy in restoring the lost folder.
to remove the New OpenDocument Text
from the menu, go to Registry Editor:
HK_CLASSES_ROOT > .odt > opendocument.WriterDocument.1
There you will see the ShellNew entry,
remove it. After you do it, refresh your desktop and you won’t see the New
OpenDocument Text entry anymore. Do that for any of the other filetypes you want
