I want my Windows 7 to get windows update from my local WSUS server instead of getting updates from the internet.
Make Windows to get updates from WSUS
There are two parameters you need to tell Windows where to get the updates.
On Specify intranet Microsoft update service location you need to set the hostname or IP address of the WSUS server and enable it.
Use regedit to check the settings. The registry path is Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
Download the updates
Got an error 80072EE6, this is because the WSUS URL is misconfigured.
Updates need to be approved prior for the client stations to download. WSUS will advise how many needed updates are for the machines.
