What you need to know

  • June's "Patch Tuesday" updates are now available for Windows 10 PCs.
  • The cumulative updates contain no new features, but pack several bug fixes.
  • The updates are available now via Windows Update.

Microsoft is pushing out the latest round of "Patch Tuesday" updates for Windows 10 PCs today. As usual with these monthly updates, there are no new features to check out. However, the cumulative updates rolling out today bring fixes for people running the Windows 10 May 2019 Update and older.

For anyone running the May 2019 Update, you'll pick up KB4503293, which ticks the build number up to 18362.175. Here's what's included:

  • Addresses a security vulnerability by intentionally preventing connections between Windows and Bluetooth devices that are not secure and use well-known keys to encrypt connections, including security fobs. If BTHUSB Event 22 in the Event Viewer states, "Your Bluetooth device attempted to establish a debug connection….", then your system is affected. Contact your Bluetooth device manufacturer to determine if a device update exists. For more information, see CVE-2019-2102 and KB4507623.
  • Security updates to Windows Virtualization, Microsoft Scripting Engine, Internet Explorer, Windows App Platform and Frameworks, Windows Input and Composition, Windows Media, Windows Shell, Windows Server, Windows Authentication, Windows Cryptography, Windows Storage and Filesystems, Windows SQL Components, the Microsoft JET Database Engine, and Internet Information Services.

For PCs on the October 2018 Update, KB4503327 brings a little more to the table with build 17763.557. Here's a look:

  • Addresses an issue that may prevent the Windows Mixed Reality keyboard from rendering correctly in some applications.
  • Addresses a security vulnerability by intentionally preventing connections between Windows and Bluetooth devices that are not secure and use well-known keys to encrypt connections, including security fobs. If BTHUSB Event 22 in the Event Viewer states, "Your Bluetooth device attempted to establish a debug connection….", then your system is affected. Contact your Bluetooth device manufacturer to determine if a device update exists. For more information, see CVE-2019-2102 and KB4507623.
  • Addresses an issue that may prevent the Preboot Execution Environment (PXE) from starting a device from a Windows Deployment Services (WDS) server configured to use Variable Window Extension. This may cause the connection to the WDS server to terminate prematurely while downloading the image. This issue does not affect clients or devices that are not using Variable Window Extension.
  • Adds updated Broadcom Wi-Fi firmware to Microsoft HoloLens. For more information, see Advisory 190016.
  • Addresses an issue that may prevent Internet Explorer 11 from opening if the Default Search Provider is not set or is malformed.

The April 2018 Update, meanwhile, will see KB4503286, pushing the build number to 17134.829. Here's what's included:
