Microsoft released a new cumulative update to Window Insider program Slow, Fast and Release Preview rings. If you have updated to Build 18356.30 or a later build – your device will be offered this build. This update also includes updates that come as part of the normal monthly release cycle. Key changes include:
- Provides protections against a new subclass of speculative execution side-channel vulnerabilities, known as Microarchitectural Data Sampling, for 64-Bit (x64) versions of Windows (CVE-2019-11091, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130). Use the registry settings as described in the Windows Client and Windows Server articles. (These registry settings are enabled by default for Windows Client OS editions and Windows Server OS editions).
- Addresses an issue that decreases Internet Explorer’s performance when you use roaming profiles or you don't use the Microsoft Compatibility List.
- Addresses an issue that may cause the text, layout, or cell size to become narrower or wider than expected in Microsoft Excel when using the MS UI Gothic or MS PGothic fonts.
- Adds "gov.uk" to the HTTP Strict Transport Security Top Level Domains (HSTS TLD) for Internet Explorer and Microsoft Edge.
