Invalid URLs in (KB5023706, KB5025239) after UUP conversion

Windows[English]At the end of March 2023, Windows 11 switched to UUP. This seems to have led to collateral damage, as a blog reader told me this week. As a result, the offline package is shipped with invalid URLs, which then causes problems. Here is a brief overview of what is currently known.


Switching to UUP with Windows 11

I had reported in the blog post Reminder: UUP updates for Windows coming on March 28, 2023 that Microsoft had made its Unified Update Platform (UUP) active on March 28, 2023. 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 ship with an update, but administrators may need to prepare WSUS or SCCM accordingly.
