Windows 10 Updates KB4497934, KB4499183 (May 21, 2019)

[German]On May 21, 2019 (3rd Tuesday of the month), Microsoft released several cumulative updates for Windows 10 (V1809 and V1803) and its Windows Server counterparts. Here is an overview of the relevant packages

Remarks on Windows 10 Updates

The information can be found in the Windows 10 Update History page. Please note that support for older Windows 10 versions has expired. Windows 10 Home and Windows 10 Pro will then no longer receive updates.

Feature updates are not auto installed

Starting with the May 21, 2019 updates (for example, Update KB4497934), Microsoft changes the procedure for upgrading to new versions of Windows 10. Users can decide when to install feature updates. I reported about this in the blog post Windows 10 May 2019 Update brings back Update control. This method was recently tested for the first time (see Windows 10 V1903 update KB4497093 with new distribution method).

In the Event Viewer, Event 31000 shows the source as "Microsoft-Windows-AssignedAccess/Admin" and displays the error message, "The group used to assign the application can't be found."
• Addresses an issue that prevents a Generation 2 virtual machine from starting on a Windows Server 2019 Hyper-V host. In the Microsoft-Windows-Hyper-V-Worker-Admin event log, Event ID 18560 displays, "VM name was reset because an unrecoverable error occurred on a virtual processor that caused a triple fault."

This update is optional and will only be offered if the user explicitly requests the search for updates in the settings page.
