KB3074679 Windows Update released for Windows 10 Build 10240

by AshwinJuly 24, 2015

Microsoft has announced the release of KB3074679 Windows Update, for Windows 10 Build 10240.

KB3074679-Windows-Update-Windows-10

This is the third update for the so-called “RTM” build.

I almost didn’t notice the update had been downloaded automatically, and had it not been for the notification sound, I might have well missed it. A quick check on the action center, revealed that a message read “Restart required for updates”. It is really annoying to have to reboot after every update, but we have no choice.

And the Windows Update said that “Security Update for Windows 10 for x64-based Systems (KB3074679” was available. Since Microsoft does not reveal much about the changes in the Windows Update tab, and neither did Gabe Aul, who tweeted the following.

 #WindowsInsiders Another update now available on Windows Update for Windows 10 PC build 10240.

But it appears that Microsoft had already updated the knowledge base with details about the update. It was, as I suspected, yet another “Cumulative Security Update for Windows 10”.

Oddly enough, the article for KB3074679 reports about fixing three issues which have already been fixed recently. This includes the security vulnerability found in OpenType Fonts (fixed in KB3079904), Adobe Flash Player security holes in Internet Explorer (fixed in KB3074665), and an issue which allowed admin rights for custom scripts incorrectly executed by Windows Installer service (fixed in KB3074674).

This was followed by a message which stated that the update also includes “non–security-related changes” for adding new features and improving the performance of the operating system. This is actually a generic note which I have seen many times, in recent KB articles.

I think there is more to it than meets the eye, else why would the Redmond company re-release patches for issues which have already been fixed. Perhaps it checks whether the previous updates were successfully installed, or fixes issues related to failed installs for recently released updates, I did come across a few reports which mentioned such issues. But nevertheless, this proves the clause about Windows as a service, which requires all prior updates to be installed, to continue receiving updates.

If you haven’t received the update already, head over to the Settings App > Update & Security > Windows Update to download the update.

On a side note, Microsoft has also released KB3074686, which improves the out-of-box experience (OOBE) for Windows 10 installs.

Windows 10 is launching in five days from now, i.e., July 29th, and Microsoft appears to be ironing out issues rapidly. We only hope the final Build launches without any major bugs or security issues.
