Microsoft releases Windows 10 build 15063.483, 14393.1480 and 10586.1007 - here's what's new

It's Patch Tuesday, which means that it's once again time for Microsoft to upgrade all versions of Windows 10. This includes the original version, currently known as 1507, even though Microsoft had said that it was ending support for it back in May.

If you're on the Creators Update, you're going to see build 15063.483, or KB4025342, which is available for PCs and phones. You can find it on the Microsoft Update Catalog here. This is what got fixed:

  • Addressed issue introduced by KB4022716 where Internet Explorer 11 may close unexpectedly when you visit some websites.

  • Addressed issue to improve MediaCreationTool.exe support for Setup Tourniquet scenarios.

  • Addressed issue with CoreMessaging.dll that may cause 32-bit apps to crash on the 64-bit version of the Windows OS.

  • Addressed an issue where Visual Studio or a WPF application may terminate unexpectedly (stops responding, followed by a crash) when running on a pen and/or touch enabled machine with Windows 10 Creators Update.

  • Addressed issue that causes the system to crash when certain USB devices are unplugged while the system is asleep.

  • Addressed issues with screen orientation that stops working after lid close and lid open transitions.

  • Addressed issue that causes .jpx and .jbig2 images to stop rendering in PDF files.

  • Addressed issue where users could not elevate to Administrator through the User Account Control (UAC) dialog when using a smart card.

  • Addressed issue where input using the Korean handwriting feature dropped the last character of a word or moved it to the next line incorrectly.

  • Addressed issue with a race condition between the App-V Catalog Manager and the Profile Roaming Service. A new registry key is available to control the waiting period for App-V Catalog Manager, which allows any third-party Profile Roaming Service to complete.

  • Security updates to Internet Explorer 11, Microsoft Edge, Windows Search, Windows kernel, Windows shell, Microsoft Scripting Engine, Windows Virtualization, Datacenter Networking, Windows Server, Windows Storage and File Systems, Microsoft Graphics Component, Windows kernel-mode drivers, ASP.NET, Microsoft PowerShell, and the .NET Framework.

There's an important note too, which also applies to the 1507 update:

  • After installing the security updates for CVE-2017-8563, administrators need to set registry key LdapEnforceChannelBinding to enable the fix for the CVE. For more information about setting the registry key, see Microsoft Knowledge Base article 4034879.

Finally, there is a known issue in this update that you should be aware of if you're using Comodo Internet Security Suite:

Symptom Workaround/Mitigation
If you have not installed the latest version of Comodo Internet Security Suite, you will not have this Windows Update offered to your device automatically.

Next up is build 14393.1480, which is for devices that are on the Anniversary Update, or version 1607. It's available for PCs, and phones that weren't eligible for the Creators Update. You can download KB4025339 manually here. Here's what's new:

  • Addressed issue introduced by KB4022723 where Internet Explorer 11 may close unexpectedly when you visit some websites.
