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.
