Every time I appear to have a huge memory leak / svchost shows to be using between 600MB and 1.5 gb of RAM in taskmanager. In the meanwhile, having found the culprit service (Windows Update) if I disable the Windows update service, the svchost.exe memory drops to like 80mb and the system speeds up, as desired.

Now the question, how can I fix the Windows update service, what can be the cause, if this happens im not using Windows update and its just idling (not checking, or installing updates) the huge spikes usually happen from system start to service shutdown or a long time after bootup if i don't. I cannot enjoy speed on my Vista PC without having toggled the service off temporarily.. Windows is up to date well with SP2 so it cant be a patch to mem leak i missed out on, either.
