KB4503327 Windows 10 1809 17763.557 Cumulative update improvements and fixes

Here is the changelog of the update –

  • The patch addresses Windows Mixed Reality keyboard that cannot render correctly in some applications.
  • KB4503327 includes an improvement for security vulnerability via intentionally obstructing connections between Bluetooth devices and Windows 10. This is for the devices that are not secure and use familiar keys to encrypt connections, including security fobs. Your system gets affected after BTHUSB Event 22 in the Event Viewer says – “Your Bluetooth device attempted to establish a debug connection……” In such a situation, you need to go to your Bluetooth device manufacturer in order to ascertain if any updates exist. For details, read KB4507623 and CVE-2019-2102.
  • Cumulative update tries to settle down “Preboot Execution Environment (PXE)” that cannot start a device from a “Windows Deployment Services” server which is configured to use Variable Window Extension. The bug will possibly lead the connection to the “WDS server” to terminate prematurely during downloading the image. This problem doesn’t have an impact on either clients or devices who are not running the Variable Window Extension.
  • The patch includes updated Broadcom WiFi firmware in Microsoft HoloLens. See details here – Advisory 190016.
  • KB4503327 Patch Tuesday package addresses Internet Explorer 11 that cannot open if the Default Search Provider is not set or is malformed.
  • This cumulative update includes Security updates to various Microsoft components.
