Information on files' associations are stored in
HKCU\SOFTWARE\Classes Windows' registry branches (among others). Each entry there can have
OpenWithProgIDs key which adds programs named in it's values to the list of programs accessible from Open With entry in the context menu. Many of these keys have
REG_NONE type. However regedit doesn't allow to create keys of this type - this type is absent from the list of key types available under New entry of the context menu.
How can I create a registry key of type
REG_NONE to add new program to the list or to recreate previously deleted key?
