Windows 10 Build 16299.611 changelog
Microsoft has announced KB4343897 in the Windows support site referred it as “August 14, 2018—KB4343897 (OS Build 16299.611)”. If you’re already running the Windows 10 version 1709 on your PC, this update will address these problems:
Fixed bug KB4343897
- Offers protection against a new speculative “side-channel vulnerability” known as L1 Terminal Fault (L1TF) involving Intel® Core® processors and Intel® Xeon® processors (CVE-2018-3620 and CVE-2018-3646). Ensure that previous operating system protections against Specter Variant 2 and Meltdown vulnerabilities are enabled using the registry settings. (These registry settings are enabled by default for Windows Client OS editions, but disabled by default for Windows Server OS editions.)
- Fixes a problem that causes high CPU utilization, which leads to performance degradation on some systems with 15h and 16h family AMD processors. This issue occurs after installing the Windows Updates from Microsoft in June 2018 or July 2018 and the AMD microcode updates that address Specter Variant 2 (CVE-2017-5715 – Branch Target Injection).
- Update support for the draft version of the token binding protocol v0.16.
- Fixes an issue that causes Device Guard to block some ieframe.dll class IDs after installing the May 2018 cumulative update.
- Ensures that Internet Explorer and Microsoft Edge support the preload = “none” tag.
- Fixes an issue that displays “AzureAD” as the default domain on the login screen after installing the update on July 24, 2018 on a hybrid Azure AD-joined machine. As a result, users can not log in to hybrid Azure AD-joined scenarios by only providing their username and password.
- Fixes an issue where content that has been copied from Internet Explorer to other applications is given extra space.
- Fixes a vulnerability related to the export module member () function when used with a wildcard (*) and a dot sourcing script. After installing this update, existing modules on devices with Device Guard enabled will fail intentionally. The exception is “This module uses the dot source operator when exporting functions with wildcard characters, and this is not allowed when the system is in the application validation”.
- Security updates for Windows Server.
Known Issue #1:
Some non-English platforms may display the following string in English instead of the localized language: ”Reading scheduled jobs from file is not supported in this language mode.” This error appears when you try to read the scheduled jobs you’ve created and Device Guard is enabled”
Known Issue #2:
When Device Guard is enabled, some non-English platforms may display the following strings in English instead of the localized language:
- “Cannot use ‘&’ or ‘.’ operators to invoke a module scope command across language boundaries.”
- “‘Script’ resource from ‘PSDesiredStateConfiguration’ module is not supported when Device Guard is enabled. Please use ‘Script’ resource published by PSDscResources module from PowerShell Gallery.”
Known Issue #3:
After you install any of the July 2018 .NET Framework Security Updates, a COM component fails to load because of “access denied,” “class not registered,” or “internal failure occurred for unknown reasons” errors. The most common failure signature is the following:
Exception type: System.UnauthorizedAccessException
Message: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
