This security update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:

  • Addressed issue where UI elements, including menu bars, are missing from Windows and Java applications running on computers with multiple monitors (multimon).

  • Addressed issue where the WordPad application can sometimes crash on launch. The was a known issue first reported in KB4025337.

  • Re-release of MS16-087- Security update for Windows print spooler components.

  • Addressed issue where applications that have LDAP referral chasing options enabled use a TCP dynamic port connection that doesn’t close until the applications close or the calling OS restarts. With sufficient time and volume, these applications may completely consume all TCP dynamic ports. If that occurs, network communications will fail for any protocol or operation that uses dynamic ports. This issue was introduced by the July and August 2017 cumulative updates, starting with KB4025337 and KB4025341.

  • Security updates to Microsoft Graphics Component, Windows kernel-mode drivers, Windows shell, Windows Hyper-V, Windows kernel, and Windows Virtualization.
