IVsChangeTrackingUndoManager allows you to remove the asterisk in the title bar, which indicates that the document has been changed, or is dirty. For example, a user opens a document, types a character and hits undo. If you do not use IVsChangeTrackingUndoManager, the document remains dirty and does not revert to the clean state.

Notes to Callers Call this interface to receive notification of when a document returns to the clean state. To obtain a pointer to IVsChangeTrackingUndoManager, call QueryInterface on IOleUndoManager for IID_IVsChangeTrackingUndoManager. Call AdviseTrackingClient to receive notification from the undo manager of when the document is clean following an undo action.
