When the customer must become a geek to stop services and unistall video and sound drivers to get Windows updates to install then it is "Houston, we have a problem." time. After getting the updates working I now get intermittent .Net Framework error messages.
Do you have .Net Framework installed? It's the same as on 7, you need to add it through Control Panel, Programs & Features, Add or Remove Windows Features, Dotnet 2.0 & 3.0 (it's one selection for both).
Many apps don't use 4.0 yet, so just check if it is active. I had to activate it today, because I needed to install a Vodafone modem.
