Note: Additional information on these improvements is not available. The VSTS bug number provided with each improvement is a unique ID that you can give Microsoft Customer Support, include in StackOverflow commentsor use in web searches.

Security Compliance Guidance

This guidance is for companies that want to install the minimum set of security updates each month. If you want security and quality updates, do not follow this guidance.

Guidance for this month:

• Install Windows 10 updates (the Windows 10 LCU).
• Do not install pre-Win10 .NET Framework updates.

Explanation: .NET Framework updates for Windows 10 are included with the Windows 10 LCU (which include Windows security updates), while pre-Windows 10 .NET Framework updates are separate updates (which only include quality updates this month).

Note: You can look at the Classification release attribute to see if a .NET Framework update falls under either “Security Updates” or “Updates” category. See this month’s Windows 10 1709 and Windows 7 releases as examples.

The Security and Quality Rollup is available via Windows Update, Windows Server Update Services, Microsoft Update Catalog, and Docker.
