Windows Vista Errore windows update kb921896

[skek]

Windows Update dice che c'è un aggiornamento importante da installare:

Microsoft sql Server 2005 Express Edition Service Pack 2 (KB 921896).

Però il sistema non riesce ad installare questo aggiornamento restituendomi
l'errore: 8004100F

Girando un pò sul forum ho visto che potrebbe essere utile inserire il
