Cumulative Update KB4497935 for Windows 10 v1903, May 29, 2019

Microsoft is releasing a new cumulative update for Windows 10 version 1903 'May 2019 Update'. The patch KB4497935 raises the operating system version to build 18362.145, and comes with the following change log.

Key changes include:

• Addresses an issue that may prevent Custom URI Schemes for Application Protocol handlers from starting the corresponding application for local intranet and trusted sites on Internet Explorer.
• Addresses an issue that prevents certain apps from launching when you set folder redirection for the Roaming AppData folder to a network path.
• Addresses an issue that my turn off Night light mode during display mode changes.
• Addresses an issue that may distort the rendering of a full-screen game when the Microsoft Game bar is visible on top of the game.
• Addresses an issue that prevents the removal of Bluetooth® peripheral devices from some systems with specific Bluetooth radios.
• Addresses an issue that may cause event 7600 in the Domain Name System (DNS) server event log to contain an unreadable server name.
• Addresses an issue in which the dots per inch (DPI) of the guest does not match the host.
• Addresses an issue that may cause an external USB device or SD memory card to be reassigned to an incorrect drive during installation. For more information, see "This PC can't be upgraded to Windows 10" error on a computer that has a USB device or SD card attached.
• Addresses an issue in which a File Share Witness does not remove Server Message Block (SMB) handles, which causes a server to eventually stop accepting SMB connections.
• Addresses an issue that prevents an application protocol URL from being opened when hosted on an intranet page.
• Addresses an issue with BranchCache when it is in distributed cache mode. BranchCache may use more disk space than assigned for the republication cache. To fully address the issue, devices that have exceeded the disk space assignments should empty BranchCache using the netsh branchcache flushcommand.
• Addresses an issue that may prevent some Direct3D applications and games from entering full-screen mode if the display’s orientation has been changed from the default.
• Addresses an issue with creating a Windows catalog file on an x64 system using Windows System Image Manager. For more information, see What's new in ADK kits and tools.
• Addresses an issue that causes a delay when loading many unsigned Domain Name System (DNS) zones related to the Domain Name System Security Extensions (DNSSEC) feature. This issue occurs after configuring the following registry setting:

Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters

Setting: EnableFastLoadUnsignedZones

Type: DWORD Value: A value of 1 enables the feature. A value of 0 disables the feature.

Restart the operating system or the DNS server after changing the registry values.
