Features and fixes KB4343909 (17134.228) 1803

This update includes quality updates. New functions of the system are not presented. List of key changes:

Added protection against the speculative performance vulnerability of the side channel, known as L1 Terminal Fault (L1TF). The vulnerability affects Intel® Core® and Intel® Xeon® processors (CVE-2018-3620 and CVE-2018-3646). Ensure that previous safeguards against the Spectre Variant 2 and Meltdown vulnerabilities are enabled by using the system registry settings.
Fixed a problem that led to increased CPU consumption and performance degradation in systems with AMD Family 15h and 16h processors. This problem manifested itself after the installation of Windows updates from June 2018 and July 2018, as well as updates to the AMD firmware, which fixes the Spectre Variant 2 vulnerability (CVE-2017-5715 – manipulation of target branch address cache).
Fixed a problem that blocked receiving the distributed updates after the resume. Problems were observed in applications that used the spatial mapping grid and took part in the cycles “Dream” and “Renewal”.
Added support for preloading the “none” tag in Internet Explorer and Microsoft Edge.
Fixed an issue that prevented authentication in some applications running in HoloLens, such as a remote assistant. The problem manifested itself after the Windows 10 update from version 1607 to 1803.
Fixed an issue that significantly increased power consumption after upgrading to Windows 10 April 2018 Update (1803).
The problem that led to the blocking of ieframe.dll class identifiers by the Device Guard component after the installation of cumulative updates from May 2018 was fixed.
The vulnerability associated with the Export-Modulemember () function and the use of metacharacter (*) with a dot-sourcing script have been fixed. After installing the update, existing modules on the device for which Device Guard is enabled will intentionally shut down the system.
Security updates for Windows Server.

If you installed previous updates, this time only the new changes in the composition of the cumulative package will be applied.
