I have just received build 10158 and am trying to update to 10159. I am on a Wireless network with 10Mbps bandwidth. When the Windows Update service is trying to get the new build all computers on the local network are unable to browse the Internet. When I switch off the Delivery Optimization service browsing capability is immediately restored.
I suspect this has to do with the number of connections where the Delivery Optimization service is trying to discover nearer parts of the build else where on the local network or on the Internet. I have tried turning off the option to look on both the local network and on the Internet and selecting just the local network, but there is no option to turn this feature off except for disabling the service entirely via the Service control panel.
Is this a known issue and one of the reasons 10158 was replaced with 10159?
