Did you know that 80% of the content in Microsoft Update (MU) is drivers? Drivers represent a huge amount of content, so if your organization has standard devices, or you know what drivers are needed by your users, you can dramatically reduce the amount of metadata and content in your WSUS server by not syncing the "Drivers" category to WSUS.
Instead, you can selectively import drivers from the catalog by using a feature in the WSUS UI. Please note, this is only available through a WSUS Management Console of same version as the WSUS Service that is connected to in remote scenarios.
Once you have downloaded the update using the Microsoft Update Catalog, the update will appear in "All updates." From there, you can approve the update, assign it to target groups, and set deadlines.
