May's 'Patch Tuesday' updates are now rolling out to Windows 10

All eyes may be on Build 2018 this week, but it's also Patch Tuesday, which means Microsoft has updates to ship out. As with prior Patch Tuesday releases, May's include bug fixes and security improvements for Windows 10 PCs. This month also happens to be the first Patch Tuesday release for the Windows 10 April 2018 update.

For April 2018 Update users, May's update is rolling out as KB4103721 and build 17134.48. Here's a look at what's fixed:

  • Addresses an issue with the April 2018 Windows Servicing update that causes App-V Scripts (User Scripts) to stop working.
  • Addresses an issue that prevents certain VPN apps from working on builds of Windows 10, version 1803. These apps were developed using an SDK version that precedes Windows 10, version 1803, and use the public RasSetEntryProperties API.
  • Addresses an issue that may cause some devices to stop responding or working when using applications, such as Cortana or Chrome, after installing the Windows 10 April 2018 Update.
  • Addresses additional issues with updated time zone information.
  • Addresses an issue that may cause an error when connecting to a Remote Desktop server. For more information, see CredSSP updates for CVE-2018-0886.
  • Security updates to Windows Server, Microsoft Edge, Internet Explorer, Microsoft scripting engine, Windows app platform and frameworks, Windows kernel, Microsoft Graphics Component, Windows storage and filesystems, HTML help, and Windows Hyper-V.

If you're still on the Fall Creators Update, you'll see KB4103727 with version 16299.431. Here's what's been fixed:

  • Addresses an issue in Internet Explorer that might cause communication between web workers to fail in certain asynchronous scenarios that involve multiple visits to a web page.
  • Updates Internet Explorer and Microsoft Edge to respect the video preload flag in certain scenarios.
  • Addresses an issue on AMD platforms that causes intermittent loss of USB port functionality after resuming from Hibernate (S4).
  • Increases the user account minimum password length in Group Policy from 14 to 20 characters.
  • Addresses an issue with the April 2018 Windows Servicing update that causes App-V Scripts (User Scripts) to stop working.
  • Addresses an issue that prevents customers from typing Hangul correctly with Microsoft's Korean IME in Microsoft Word Online.
  • Addresses an issue that prevents customers from selecting a Microsoft add-in on a second monitor.
  • Addresses a known issue in KB4093105 that may cause the message "We couldn't download Windows Mixed Reality software" to appear on some Windows 10 Mixed Reality devices.
  • Addresses an issue that may cause an error when connecting to a Remote Desktop server. For more information, see CredSSP updates for CVE-2018-0886.
  • Security updates to Microsoft Edge, Internet Explorer, Microsoft scripting engine, Windows app platform and frameworks, Device Guard, Windows kernel, Microsoft Graphics Component, Windows storage and filesystems, Windows Hyper-V, Windows virtualization and kernel, HTML help, and Windows Server.

The Fall Creators Update patch also includes a single known issue:

  • Some non-English platforms may display the following string in English instead of the localized language: "Reading scheduled jobs from file is not supported in this language mode." This error appears when you try to read the scheduled jobs you've created and Device Guard is enabled.

Microsoft says it is working on a solution for the issue, and it will be provided in an upcoming release.

Patch Tuesday updates are also rolling out to other currently supported versions of Windows, including older Windows 10 releases and Windows 10 Mobile.
