Back in October of 2022, Microsoft had announced the public preview of on-premises UUP (Unified Update Platform) which promised faster and smaller Windows updates. About a month and a half before the rollout, the company shared more details about UUP claiming up to 30% faster and smaller downloads. Microsoft also added that .NET update performance will also be significantly better on Windows 11 22H2 due to as .NET Framework updates would now be a part of UUP as well. Of course, it wasn't bug-free as there was a WSUS upgrade issue caused by the accidental removal of necessary UUP MIME types.
UUP on premises finally began rolling out at the end of March and Microsoft re-assured that udates sizes would be slimmer after an initial one-time 10GB download. As it has been a month since then, Microsoft has shared a helpful FAQ today. This FAQ covers a lot of the best practices that IT and system admins should be aware and it is based on the feedback Microsoft has received.
