Disables the ability of a shortcut or window to be pinned to the taskbar or the Start menu. This property also makes the item ineligible for inclusion in the Start menu's Most Frequently Used (MFU) list.
This property must be set on a window before the PKEY_AppUserModel_ID property. After the PKEY_AppUserModel_ID property is set, changes to PKEY_AppUserModel_PreventPinning are ignored.
For more information about Application User Model IDs (AppUserModelIDs) and other methods of excluding an item from being pinned to the taskbar and from MFU inclusion, see Application User Model IDs (AppUserModelIDs).
To set this property on a window, use SHGetPropertyStoreForWindow to retrieve the window's property store, and use the methods of that retrieved IPropertyStore object to set the System.AppUserModel.PreventPinning property of that window.
Setting this property causes the following properties to be ignored:
