As we continue to wait for Microsoft to make the Windows 10 Fall Update publicly available, the company rolls out a new small cumulative update, which Microsoft simply calls “Cumulative update for Windows 10: November 10, 2015”.
The update is described as KB3105213 and it brings functionality improvements and resolves various security issues in the operating system, including the following issues:
- KB3105256 MS15-122: Security update for Kerberos to address security feature bypass.
- KB3104521 MS15-119: Security update in TDX.sys to address elevation of privilege.
- KB3104507 MS15-118: Security updates in the .NET Framework to address elevation of privilege.
- KB3105864 MS15-115: Security update for Windows to address remote code execution.
- KB3104519 MS15-113: Cumulative security update for Microsoft Edge.
- KB3104517 MS15-112: Cumulative security update for Internet Explorer.
The following KB updates contain information about this security update as it relates to individual product versions.
- KB3108638 Microsoft security advisory: Update to Hyper-V to address CPU weakness.
- KB3108604 Microsoft security advisory: Description of the security update for Windows Hyper-V.
Just to be clear update KB3105213 is not the Windows 10 Fall Update (Threshold 2), it’s a just another regular maintenance update. It’s also a cumulative update, therefore the package contains all the previously released fixes.
It’s worth to point out that Insiders running Windows 10 build 10586 will get the KB3105211 update, which Microsoft named “Cumulative update for Windows 10 version 1511: November 10, 2015” and fixes exactly the same issues.
Finally, Internet Explorer also gets updated with KB3103688, which includes fixes for Flash Player on Windows 10.
If your computer is up to date, only the new changes will download and install. The update should install automatically, but you can always go to Settings > Update & security > Windows update to check for the new update.
