Defective putty, or cracked putty, will need to be removed before any new putty can be applied.

Some of the putty is likely to break away during the cleaning and preparations of old window frames.   After preparing surfaces, the bare timber can be primed and any defective putty be replaced with a new putty.    Any defective putty that has not broken away, will be fixed to the window frame and will not need to be replaced.  There may be a gap between the old putty and the window whereby a new putty will have to be forced into the space in order to prevent further water ingress.  This gap must be completely resealed by forcing in a new putty using a putty knife.
