  • Addresses an issue where touch and mouse events were handled differently in Windows Presentation Foundation (WPF) applications that have a transparent overlay window.
  • Addresses a reliability issue in applications that have extensive window nesting.
  • Addresses an issue in the Universal CRT that sometimes causes the AMD64 FMOD to return an incorrect result when given very large inputs.
  • Addresses an issue in the Universal CRT that causes the _get_pgmptr() function to return an empty string.
  • Addresses an issue in the Universal CRT that causes isprint() to return TRUE for a tab when using the C locale.
  • Addresses an issue where Microsoft Edge or other UWP applications can’t perform client authentication when the private key is stored on a TPM 2.0 device.
  • Addresses an issue that causes computer certificate enrollment or renewal to fail with an “Access denied” error after installing the April 2018 update. This issue occurs when the registry process has a lower process ID (PID) than all other processes except SYSTEM.
  • Addresses an issue that, in some cases, failed to clear decrypted data from memory after a CAPI decryption operation was completed.
  • Addresses an issue that prevented the Device Guard PackageInspector.exe application from including all the files needed for an application to run correctly once the Code Integrity policy was completed.
  • Addresses an issue where not all network printers are connected after a user signs in. The HKEY_USERS\User\Printers\Connections key shows the correct network printers for the affected user; however, the missing list for network printers from this registry key isn’t populated in any app, including Microsoft Notepad, or in Devices and Printers. Printers may disappear or stop functioning.
