Notice

This update is included in the Security and Quality Rollup that's dated October 9, 2018. This update was previously released as part of the Preview of Quality Rollup on September 18, 2018.

Introduction

The September 2018 update for Windows 7 Service Pack 1 (SP1) and Windows Server 2008 R2 SP1 includes cumulative reliability improvements in .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, and 4.7.2. Additionally, this update includes cumulative quality and reliability improvements in .NET Framework 4.6 for Windows Server 2008 SP2. We recommend that you apply this update as part of your regular maintenance routines. Before you install this update, see the Prerequisites and Restart requirement sections.

Important

  • All updates for .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, and 4.7.2 require that the d3dcompiler_47.dll update is installed. We recommend that you install the included d3dcompiler_47.dll update before you apply this update. For more information about the d3dcompiler_47.dll update, see KB 4019990 for Windows 7 SP1 and Windows Server 2008 R2 SP1. Or, see KB 4019478 for Windows Server 2008 SP2.

  • If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see Add language packs to Windows.

Quality and reliability improvements

CLR1

  • Fixes an error that occurs when parsing Japanese dates that have a year number that exceeds the number of years in the Japanese era.

  • Fixes an issue that occurs when asynchronously reading a process output in which an IndexOutOfRangeException message is thrown if less than a character's worth of bytes is read at the beginning of a line.

  • Fixes an issue in the JIT compiler for a rare case of structure field assignments, as described on this GitHub page.

  • Fixes the DateTime.Now and DateTime.Utc properties so that they will always be synchronized with the system time. The DateTime and DateTimeOffset operations continue to work as they previously did.

  • Conditionally improves spin-waits in several synchronization primitives to run better on Intel Skylake and more recent microarchitectures. To enable these improvements, set the new COMPlus_Thread_NormalizeSpinWait configuration variable to 1.

  • Fixes JIT optimization that cause the removal of interlocked Compare Exchange operations.

WPF2

  • Fixes an issue that occurs in certain circumstances in which WPF applications that use the spell checker together with custom dictionaries throw unexpected exceptions and crash.

1 Common Language Runtime (CLR)
2 Windows Presentation Foundation (WPF)
