- Click Start
- Click Run
- Type in regedit and click ENTER
- Browse to the following:
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers
You simply delete or export then delete the keys you do not want.
There are several "kinds" of menu handlers, however, so you could browse to any of the following and perhaps find stuff you want to get rid of:
HKEY_CLASSES_ROOT\*\OpenWithList
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers
HKEY_CLASSES_ROOT\Directory\Background
HKEY_CLASSES_ROOT\Directory\shell
HKEY_CLASSES_ROOT\Directory\shellex\ContextMenuHandlers
HKEY_CLASSES_ROOT\Drive\shell
HKEY_CLASSES_ROOT\Drive\shellex\ContextMenuHandlers
HKEY_CLASSES_ROOT\Folder\shell
HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers
