September Windows 10 'Patch Tuesday' updates now rolling out

Today marks the second Tuesday of September, meaning it's time for Microsoft to ship out another batch of "Patch Tuesday" updates. Like prior releases, these are cumulative updates with no new features in tow. Instead, each update brings a number of fixes and addresses security issues for currently supported versions of Windows 10.

For those running Microsoft's latest Windows 10 feature update, the April 2018 Update, you'll pick up a relatively small list of fixes via KB4457128 (build 17134.285) (opens in new tab). Here's a look at what's included:

  • Provides protection against a Spectre Variant 2 vulnerability (CVE-2017-5715) for ARM64 devices.
  • Addresses an issue that causes the Program Compatibility Assistant (PCA) service to have excessive CPU usage. This occurs when the concurrency of two simultaneous add and remove programs (ARP) monitoring threads is not handled correctly.
  • Security updates to Internet Explorer, Microsoft Edge, Microsoft scripting engine, Microsoft Graphics Component, Windows media, Windows Shell, Windows Hyper-V, Windows datacenter networking, Windows virtualization and kernel, Windows Linux, Windows kernel, Microsoft JET Database Engine, Windows MSXML, and Windows Server.

Meanwhile, the Fall Creators Update and Creators Update are getting a single fix via updates KB4457142 (build 16299.665) (opens in new tab) for the former and KB4457138 (build 15063.1324) (opens in new tab) for the latter.

  • Security updates to Internet Explorer, Microsoft Edge, Microsoft scripting engine, Windows graphics, Windows media, Windows Shell, Windows cryptography, Windows virtualization and kernel, Windows datacenter networking, Windows hyper-V, Windows Linux, Windows kernel, Microsoft JET Database Engine, Windows MSXML, and Windows Server.

The above security updates are also rolling out to Windows 10 Mobile (opens in new tab) devices, along with PCs on prior versions of Windows 10.

For more, you can check out the release notes for all of today's updates at the Windows support site (opens in new tab). Otherwise, hit up Windows Update to pick up all of the latest bug and security fixes for your PC.

  • Good. I used to often see the compatibility assistant using a lot of CPU time. I hope this fixes it. Sometimes the antivirus goes nuts when not scanning too. How much wasted power does high CPU usage instead of an idle usage on 700 million PCs potentially waste?
  • Wait, there's a version of Spectre that targets ARM? Didn't hear about that.
  • ARM, AMD, Intel, all effected in some kind of way by it
    till newer device without the Vulnerability.
  • so its all about security but tell me whens 1809 is gonna release ?
  • October. Possibly on it's Patch Tuesday.
  • Rockin' 15063.1324 on my mobile device! Windows Mobile forever! (Or until 2019, whichever comes first.)
  • Finally, the security update! I really don't understand why they need IE support , when they have Edge.
  • Legacy support for those who need it.
  • great
