Is there a way to make WSUS Offline download only missing updates for current system?
I've made custom Windows 7 instalation DVD which has many updates integrated.
I would like to automate downloading and instaling updates with WSUS Offline, but I dont need download all the updates every time.

I was thinking about listing installed updates and adding them to exclusion list.
How it could be done?

Add them to the two exclusion lists for Win7, ensure they are entered properly:
ExcludeList-w61-x86.txt
ExcludeList-w61-x64.txt

You may also want to untick the uption to include Servicepacks in the Update Generator. If you already included Dotnet 3.5/4.x in your installation media you may want to remove those from \static\StaticDownloadLinks-dotnet.txt

BTW WOU downloads updates only once and keeps them until marked as replaced.
