Nick - XP64 update question

Did my monthly manual Windows Update Thursday and it completed critical updates with no problems. However, since then, it takes almost a full minute longer to load XP64. Then tried to run O&O and find that the service will not start - not manually or on auto. 
Restored to before the updates - O&O is fine & XP64 loads a minute faster.
I guess I could try the updates again but wondered if you had run into anything similar with your XP64 system?
Thanx,
Vic
