Kdyz nevis, zeptej se Woodyho....An explanation may be found at askwoody.com from @abbodi86 within this comment: they expired most of IE11 cumulative updates (around 14 updates)however, the supersedence chain for KB3008923 is now broken, the update that supersede it is expired – therefore and by metadata rules, KB3008923 is not superseded now.So, just hide update KB3008923 – and probably other updated (KB3003057 and KB2987107) within the broken update chain.
