If you are running either of these versions of Windows, you update will come in the form of KB4598242 and it includes the following highlights:
Updates to improve security when using external devices, such as game controllers, printers, and web cameras.Updates to improve security when Windows performs basic operations.
And here is the full list of fixes in today’s update:
Addresses a security vulnerability issue with HTTPS-based intranet servers. After installing this update, HTTPS-based intranet servers cannot, by default, use a user proxy to detect updates. Scans using these servers will fail if you have not configured a system proxy on the clients. If you must use a user proxy, you must configure the behavior using the policy “Allow user proxy to be used as a fallback if detection using system proxy fails.” To ensure the highest levels of security, also use Windows Server Update Services (WSUS) Transport Layer Security (TLS) certificate pinning on all devices. This change does not affect customers who are using HTTP WSUS servers. For more information, see Changes to scans, improved security for Windows devices.Addresses a security bypass vulnerability that exists in the way the Printer Remote Procedure Call (RPC) binding handles authentication for the remote Winspool interface. For more information, see KB4599464.Security updates to Windows App Platform and Frameworks, Windows Media, Windows Fundamentals, Windows Kernel, Windows Cryptography, Windows Virtualization, Windows Peripherals, and Windows Hybrid Storage Services.
If automatic updates enabled on your system, you should see the new updates in the next couple of days. Or, you can stay on top of things by manually heading to Settings > Update & Security > Microsoft Update to check. Older versions of Windows 10 are getting updates today as well. Make sure to read the documentation on the Windows 10 Update History page for your version’s full release notes. If something breaks after you install today’s updates and cannot be resolved by Microsoft’s documented workarounds you can roll them back.
