Late last night, Windows 10 spokesman Gabe Aul tweeted that there's "another update now available" for Windows 10 build 10240. He must have been referring to KB 3074679. Then sometime in the middle of the night Redmond time, KB 3074686 also flew out the Windows Update chute.
KB 3074679 is billed in the delivery window as a "Security Update for Windows 10 for x64-based Systems." The KB article explains:
This security update resolves the following vulnerabilities in Microsoft Windows:
- The vulnerability could allow remote code execution if a user opens a specially crafted document or visits an untrusted webpage that contains embedded OpenType fonts. To learn more about the vulnerability, see Microsoft Security Bulletin MS15-078.
- The vulnerability impacts Adobe Flash Player in Internet Explorer. To learn more about the vulnerability, see Microsoft security advisory 2755801 and Adobe Security bulletin APSB15-18.
- The vulnerability could allow elevation of privilege if the Windows Installer service incorrectly runs custom action scripts.
Additionally, this update includes non-security-related changes to enhance the functionality of Windows 10 through new features and improvements.
Of course, the non-security changes aren't listed or explained.
This patch triggers a reboot.
KB 3074686 is similarly labelled "Update for Windows 10 for x64-based Systems." The KB article says it's an improvement to the "Out of Box Experience" (I've always loved that phrase. I wonder if that's what Count Dracula encounters every evening) for Windows 10. Per the KB article:
This update improves the Windows 10 out-of-box experience (OOBE). This update applies only to the Windows 10 OOBE process and will be available only at the time that OOBE updates are installed.
Presumably, OOBE updates will be installed after July 29 as part of the giant whooshing sound when people first install Windows 10.
There's also a new Intel HD Graphics Driver in the update mill.
Hey, at least Microsoft posted the KB articles.
