KB3105213 Cumulative Windows Update and KB3103688 Flash Player update rolls out to Windows 10

by AshwinNovember 12, 2015

Microsoft has released two new Windows Updates for systems running on Windows 10.

Windows Update KB3103688 KB3105213 cumulative

The two updates are codenamed KB3105213 and KB3103688.


KB3105213 is a Cumulative Windows Update, and you know what that means. It mostly consists of security fixes for the operating system.

One of the bugs fixed in the update, was related to the Kerberos network authentication protocol, which could have been bypassed on computers which have BitLocker enabled. But the issue could only be exploited if the attacker had physical access to the PC, which not have a PIN or USB key, and is domain joined.

A security flaw in the Winsock, the component which enables the PC to connect to the internet, could have allowed attackers elevation of privilege (admin rights). Similar issues were found in the Microsoft .NET Framework, which involved a malicious script injected via a browser,

Bugs which could have allowed remote execution of malicious codes when the user viewed a dangerous webpage have been fixed in both Microsoft Edge and Internet Explorer.

Security issues in Windows’ Hyper-V (virtualization system), which could trigger a denial of service in some chipsets have been fixed.


KB3103688 Windows Update updates the built-in Adobe Flash Player plugin in Internet Explorer (Windows 8 and above) and Microsoft Edge, to include the latest security fixes.

And just like with all cumulative Windows Updates, you will need to restart the computer to finish installing the updates. If you would like to read more technical details about the updates, head to the official knowledgebase articles here and here.

Windows 10 Fall Update to be named 1511?

Oh and interestingly, the KB3103688 Windows Update has revealed the official name for the Windows 10 Fall Update. The knowledgebase article for the update says that the update is available for the following versions:


Microsoft Edge in Windows 10 and Windows 10 version 1511

I was still able to install the update on my computer running Windows 10 RTM Build 10240. So, the odd statement quoted by Microsoft, means the first major update for Windows 10 will be called Windows 10 version 1511. That is Fifteen Eleven, to represent the year and month it will be released in. No wonder the Microsoft Engineer who confirmed the update’s arrival a week ago, referred to it as the November Update. It’s not a really catchy name to be honest, and in fact calling it 1511 sounds more like a trivial update than a “major one”.

We are expecting Microsoft to release the Windows 10 Fall Update, er…, version 1511 sometime later today.
