[German]At the end of March 2023, Microsoft has enabled the Unified Update Platform (UUP) for Windows 11 22H2. The platform is supposed to enable smaller and easier updates, as Microsoft explained. In this context, problems and shortcomings observed by users have been described to me. Microsoft employee Stefan Röll published a post in the tech community a few days ago that goes into detail about the Unified Update Platform (UUP) in connection with Intune.

UUP support only for Windows 11
I had reported in the blog post Reminder: UUP updates for Windows coming March 28, 2023, that Microsoft had made its Unified Update Platform (UUP) avilable on that date. The platform is intended to enable smaller and easier updates, as Microsoft explained on February 9, 2023 in the article Get ready for the first UUP on premises updates coming in March.
For now, the UUP release applies only to Windows 11 version 22H2 and is intended to bring the power of Windows Update and Windows Update for Business to local Windows clients. It will be delivered with an update, but administrators may need to prepare WSUS or SCCM accordingly.
For this purpose, an update of about 10 MBytes is to be installed in March or April 2023. However, users were surprised to see another 10 GByte download for UUP in May 2023. Dietmar Haimann points out this in the tweet below.
In addition, blog readers had reported that there were problems with wsusscn2.cab after the UUP changeover (see Invalid URLs in wsusscn2.cab (KB5023706, KB5025239) after UUP conversion).

Microsoft answers UUP questions
The days I came across the following tweet from Micosoft employee Stefan Röll, who is Cloud Solution Architect at Microsoft Germany for Intune and Microsoft Configuration Manager.
Stefan Röll has received many questions from customers about the Unified Update Platform (UUP) over the past few weeks, so he answered many questions about UUP in a Techcommunity post Unified Update Platform with ConfigMgr – Questions from the Field.
According to his article, UUP updates are a game changer for on-prem environments. You can want to use features that were previously reserved for online environments. However, each cumulative update (CU) is now about 10 GB in size, which can be a challenge for slowly connected systems.
Microsoft Configuration Manager (ConfigMgr), however, uses clever technologies to limit the impact on the back end. in his article, Röll also addresses the issue of downloading 10 GB to the source directory each month after downloading the first UUP update. Anyone managing UUP and Windows 10 22H2 under ConfigMgr should read the post.
