After you set up a client computer, it will take a few minutes before it appears on the Computers page in the WSUS console.
For client computers configured with an Active Directory-based GPO, it will take about 20 minutes after Group Policy refreshes (that is, applies any new settings to the client computer).
If you enable this policy, the system does not wait for Group Policy updates to complete before inviting the user to log on.
Although there are additional Group Policy settings related to the Windows Update Web site, all the new Group Policy settings for WSUS are contained within the file.
If the computer you are using to configure Group Policy has the latest version of Wuau.adm, you do not need to load the file to configure settings.
All our GP settings apply perfectly on our Dell desktops and have never had any issues until now.
We've ordered newer Dell desktops but still running Win 7.
In a simple environment, link the GPO with the WSUS settings to the domain.
