[German]Short info and question, whether this can be confirmed. The update KB4522015 for Windows 10 V1809 dated September 23, 2019 is supposed to block the installation of the RSAT management tools.
Update KB4522015 for Windows 10 V1809
Update KB4522015 was released on September 23, 2019 for Windows 10 Version 1809, Windows Server Version 1809, and Windows Server 2019. The main purpose of this update was to close a vulnerability in Internet Explorer 11. I reported on this topic in the blog post Windows: Vulnerabilities in IE and Defender (09/23/2019).
Update KB4522015 is causing multiple issues
This security update has caused serious issues under Windows 10. After the installation there were printing issues, which Microsoft finally had to confirm (see Windows: Printer issues after Sept. 2019 Update confirmed).
I also reported that this update blocks the use of older versions of VMware Workstation on Windows 10. Details can be found in the article Windows 10: Update KB4517211/KB4522015 breaks VMware Workstation.
Is this update causing RSAT install issues?
Remote Server Administration Tools (RSAT) allow IT administrators to remotely manage roles and features in Windows Server from a computer running Windows 10, Windows 8.1, Windows 8, Windows 7, or Windows Vista. You can install RSAT only on the Professional or Enterprise editions of the Windows client operating system.
KB4522015 also breaks enabling RSAT tools installation. Uninstalling KB4522015 allows RSAT tools to install again.
Has anyone had the same experience? Since Microsoft has meanwhile released follow-up updates to close the IE vulnerabilities, the follow-up question: Are there any problems there?
