July 'Patch Tuesday' fixes now rolling out for April 2018 Update PCs

July 10 marks the second Tuesday of the month, which means its time for another batch of fixes from Microsoft. Like prior Patch Tuesday releases, July's include a number of fixes but nothing in the way of new features.

For those running the latest Windows 10 release, the April 2018 Update, today's fixes are included in KB4338819 (build 17134.165) (opens in new tab), and there aren't many to keep track of. Here's a look:

  • Improves the ability of the Universal CRT Ctype family of functions to correctly handle EOF as valid input. Enables debugging of WebView content in UWP apps using the Microsoft Edge DevTools Preview app that's available in the Microsoft Store.
  • Addresses an issue that may cause the Mitigation Options Group Policy client-side extension to fail during GPO processing. The error message is "Windows failed to apply the MitigationOptions settings. MitigationOptions settings might have its own log file" or "ProcessGPOList: Extension MitigationOptions returned 0xea." This issue occurs when Mitigation Options has been defined either manually or by Group Policy on a machine using Windows Defender Security Center or the PowerShell Set-ProcessMitigation cmdlet.
  • Evaluates the Windows ecosystem to help ensure application and device compatibility for all updates to Windows.
  • Security updates to Internet Explorer, Windows apps, Windows graphics, Windows datacenter networking, Windows wireless networking, Windows virtualization, Windows kernel, and Windows Server.

If you're still running the Fall Creators Update, there's a similarly short list of fixes rolling out as KB4338825 (build 16299.547) (opens in new tab). Here's a look:

  • Addresses an issue that, in some cases, causes the wrong IME mode to be chosen on an IME-active element.
  • Addresses an issue with form submission in Internet Explorer.
  • Addresses an issue where DNS requests disregard proxy configurations in Internet Explorer and Microsoft Edge.
  • Addresses additional issues with updated time zone information.
  • Addresses an issue that causes the latest versions of Google Chrome (67.0.3396.79+) to stop working on Cobalt devices.
  • Evaluates the Windows ecosystem to help ensure application and device compatibility for all updates to Windows.
  • Security updates to Internet Explorer, Microsoft Edge, Microsoft scripting engine, Windows apps, Windows graphics, Windows datacenter networking, Windows virtualization, Windows kernel, and Windows Server.

Similar updates are also rolling out across prior versions of Windows 10, including the Creators Update and Anniversary Update. For the full list of changes, you can check out Microsoft's comprehensive release notes (opens in new tab). Otherwise, each cumulative update should now be available to download via Windows Update.
