  • Updates Internet Explorer’s default visibility for the button that launches Microsoft Edge.
  • Addresses issue where users of SQL Server Reporting Services may not be able to use the scrollbar in a drop-down list.
  • Addresses issue that caused Windows Pro devices on the Current Branch for Business (CBB) to upgrade unexpectedly.
  • Addresses issue where applications may stop responding for customers who have internet or web proxies enabled using PAC script configurations. This is a result of a reentrancy deadlock in WinHTTP.dll. This can result in the following:

    • Internet Explorer and Microsoft Edge can’t render any content (including local computer content, local network content, or web content).
    • Cisco Jabber stops responding, which blocks messaging and telephony features.
    • Any application or service that relies on WinHTTP is affected.
  • Addresses additional issues with updated time zone information.
  • Security updates to the Microsoft Scripting Engine, Microsoft Edge, and Windows Server.
