Microsoft started rolling out a new wave of cumulative updates for Windows 10 last night. The company is releasing updates for almost all the supported versions of the OS, including the initial version of Windows 10, as well as the latest version.
As for the latest version, the Windows 10 May 2019 Update (version 1903), Microsoft has rolled out KB4503293, which brings the build number up to 18362.175. It’s a fairly minor update, and contains mostly security fixes:
- Addresses a security vulnerability by intentionally preventing connections between Windows and Bluetooth devices that are not secure and use well-known keys to encrypt connections, including security fobs. If BTHUSB Event 22 in the Event Viewer states, “Your Bluetooth device attempted to establish a debug connection….”, then your system is affected. Contact your Bluetooth device manufacturer to determine if a device update exists. For more information, see CVE-2019-2102 and KB4507623.
- Security updates to Windows Virtualization, Microsoft Scripting Engine, Internet Explorer, Windows App Platform and Frameworks, Windows Input and Composition, Windows Media, Windows Shell, Windows Server, Windows Authentication, Windows Cryptography, Windows Storage and Filesystems, Windows SQL Components, the Microsoft JET Database Engine, and Internet Information Services.
The update notably includes an issue with Windows Sandbox where the feature might not be able to start working for some users, so make sure to checkout the full changelog.
Microsoft has also released updates for the other versions of Windows 10:
If you are running any of these releases, I’d highly recommend updating your systems as soon as possible as there seem to be quite a lot of security-related fixes across the board.
