Well for 80070002 problem
http://windows.microsoft.com/zh-HK/windows-vista/Windows-Update-error-80070002
Found some info for this error~~~
But I am thinking your meaning on "360 Update", it is Chinese AntiVirus? If yes, uninstall it and try again...
Because when u tried to install Service Packs, normally, it will prompt u to disable any antivirus and problem
before u continue, u do it?
And the remaining problem...
Think that is becase of Antivirus 360...
Hope that it can help u~~~
