The full patch for .NET Framework 4.7 for Windows 7 SP1 is not detecting as relevant.
Each month Microsoft releases a “security only” update and “security quality” update (which includes non-security fixes) for .NET Framework on Windows 7. They should both detect as relevant on the same systems, for obvious reasons. This month they have sequential KB numbers, 4495587 and 4495588.
MS19-MAY: Security Only Quality Update - Security Only - Windows 7 SP1 - .NET Framework 4.6/4.6.1/4.6.2/4.7/4.7.1/4.7.2 - KB4495587 (x64)
MS19-MAY: Security Monthly Quality Rollup - Windows 7 SP1 - .NET Framework 4.6/4.6.1 - KB4495588 (x64)
4495587 is detecting as relevant on our systems, but 4495588 is not. When running Windows Update against Microsoft servers, 4495588 comes up as needed.
