Today is Patch Tuesday, the second Tuesday of the month, when Microsoft releases new cumulative updates for all supported versions of Windows 10. That includes all versions except for the first feature update, version 1511.
If you're on the Windows 10 May 2019 Update, or version 1903, you'll get KB4512508, bringing the build number to 18362.295. You can manually download it here. This month's changelog is broken down into highlights and fixes. Here is the highlight:
Updates to improve security when using Internet Explorer, Microsoft Edge, Bluetooth, networking technologies, and input devices such as a mouse, keyboard, or stylus.
Here's what got fixed:
- Addresses an issue that may prevent devices from starting up or cause them to continue restarting if they are connected to a domain that is configured to use MIT Kerberos realms. Domain controllers and domain members are both affected.
- Security updates to Windows App Platform and Frameworks, Windows Storage and Filesystems, Microsoft Scripting Engine, Windows Input and Composition, Windows Wireless Networking, Windows Cryptography, Windows Datacenter Networking, Windows Virtualization, Windows Storage and Filesystems, the Microsoft JET Database Engine, Windows Linux, Windows Kernel, Windows Server, Windows MSXML, Internet Explorer, and Microsoft Edge.
Also, there are a few known issues to be aware of:
|Windows Sandbox may fail to start with "ERROR_FILE_NOT_FOUND (0x80070002)" on devices in which the operating system language is changed during the update process when installing Windows 10, version 1903.||Microsoft is working on a resolution and will provide an update in an upcoming release.|
|Devices that start up using Preboot Execution Environment (PXE) images from Windows Deployment Services (WDS) or System Center Configuration Manager (SCCM) may fail to start with the error "Status: 0xc0000001, Info: A required device isn't connected or can't be accessed" after installing this update on a WDS server.||
For mitigation instructions, see KB4512816.
We are working on a resolution and will provide an update in an upcoming release.
If you're on an older version of Windows 10, you'll also get a cumulative update today, which fixes some things, but may also add some known issues to be aware of:
