Microsoft rolled another update out, KB4056892 basically fixes stuff from the latest patchday back last year. After applying the update you OS gets updated to 16299.192.

There also other out-of-patchday updates released today like KB4056888 , KB4056890KB4056891 and KB4056893.

Improvements and fixes
This update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:

  • Addresses issue where event logs stop receiving events when a maximum file size policy is applied to the channel.
  • Addresses issue where printing an Office Online document in Microsoft Edge fails.
  • Addresses issue where the touch keyboard doesn’t support the standard layout for 109 keyboards.
  • Addresses video playback issues in applications such as Microsoft Edge that affect some devices when playing back video on a monitor and a secondary, duplicated display.
  • Addresses issue where Microsoft Edge stops responding for up to 3 seconds while displaying content from a software rendering path.
  • Addresses issue where only 4 TB of memory is shown as available in Task Manager in Windows Server version 1709 when more memory is actually installed, configured, and available.
  • Security updates to Windows SMB Server, the Windows Subsystem for Linux, Windows Kernel, Windows Datacenter Networking, Windows Graphics, Microsoft Edge, Internet Explorer, and the Microsoft Scripting Engine.

More information is available here. The KB is on the catalog and downloadable as direct link (around 1 GB). I haven’t had much problems with the update but I’m in general a lucky guy because I use a homebrew Windows 10 version which means I not face much issue since a lot of features are excluded.

Update

In the meantime Microsoft released the Update for all current Operation Systems.

I also changed the topic (link is the same) to make it clear that Intel/MS are aware of the problems and that there already fixes available.
