Update KB5019959 fixes and changes for Windows 10

These are the fixes and improvements coming to the next update of Windows 10:

  • Addresses security issues for your Windows operating system.
  • Addresses an issue that affects Distributed Component Object Model (DCOM) authentication hardening. It automatically raises the authentication level for all non-anonymous activation requests from DCOM clients to RPC_C_AUTHN_LEVEL_PKT_INTEGRITY. This occurs if the authentication level is below Packet Integrity.
  • Addresses a DCOM issue that affects the Remote Procedure Call Service (rpcss.exe). It raises the authentication level to RPC_C_AUTHN_LEVEL_PKT_INTEGRITY instead of RPC_C_AUTHN_LEVEL_CONNECT if RPC_C_AUTHN_LEVEL_NONE is specified.
  • Addresses an issue that causes an OS upgrade to stop responding, and then it fails.
  • Addresses an issue that affects the Microsoft Azure Active Directory (AAD) Application Proxy connector. It cannot retrieve a Kerberos ticket on behalf of the user. The error message is, “The handle specified is invalid (0x80090301).”
  • Addresses an issue that affects the font of three Chinese characters. When you format these characters as bold, the width size is wrong.
  • Addresses an issue that affects Microsoft Direct3D 9 games. The graphics hardware stops working if the hardware does not have a native Direct3D 9 driver.
  • Addresses graphical issues in games that use Microsoft D3D9 on some platforms.
  • Addresses an issue that affects Microsoft Edge when it is in IE Mode. The titles of pop-up windows and tabs are wrong.
  • Addresses an issue that affects Microsoft Edge IE mode. It stops you from opening webpages. This occurs when you enable Windows Defender Application Guard (WDAG) and you do not configure Network Isolation policies.
  • Addresses an issue that might cause an application to stop responding. This might occur when the input queue overflows.
  • Addresses an issue that affects input method editors (IME) from Microsoft and third parties. They stop working when you close the IME window. This occurs if the IME uses Windows Text Services Framework (TSF) 1.0.
  • Addresses an issue that affects the lasso tool in a graphics editing program.
  • Addresses an issue that affects Miracast advertisements. This issue occurs on Surface Hub devices under certain conditions.
  • Addresses an issue that affects some drivers. They use more power when you play hardware-protected digital rights management (DRM) content.

  • Addresses an issue that affects a remote desktop virtual desktop infrastructure (VDI) scenario. The session might use the wrong time zone.
  • It updates the Windows kernel vulnerable driver blocklist that is in the DriverSiPolicy.p7b file. This update also ensures that the blocklist is the same across Windows 10 and Windows 11. For more information, see KB5020779.
