Remove items from CONTEXT menu

When you right-click a file or folder, you'll see the list of context menu items out of which some may be invalid.

You can remove items from the context menu by editing the registry. The items are contained in the following registry key: HKEY_CLASSES_ROOT \ * \ shellex \ ContextMenuHandlers

Delete the keys for the items you don't want. Be sure to back up the registry before editing it.
