SP2 and other Service Packs

  AngeTheHippy 09:38 10 Apr 2011

Morning Chaps, this is a question that's been with me since the windows 98 days! We download windows updates, lots of 'em, then a Service Pack arrives saying that 'all previous updates are contained in this service pack'. What I'd like to know is, are those previously d/loaded updates overwritten or are they then ALL on my HDD? Thing is, in time, there will be a large chunk of HDD that's just containing updates if not overwritten, surely?

I`m pretty sure that the Service Packs only add missing security updates. For example, I have applied Windows 7 SP1 to machines that are 12 months old and it takes far less time than a brand new computer which can take about 45 minutes to download and install the service pack.

Thanks Taff™, Mmm. Interesting that Taff™. Gotta say, I've installed SP2 on Vista this morning, and it took just a few minutes. Any more comments on this please?

is right. Before downloading the SP it will scan for which updates you already have. Then only those you do not have will be added.

If disk space is an issue and SP2 is installed with no problems you can run the included clean up tool to remove old SP1 backup files. Copy and paste the link below for an explanation of its use
