lgtm - perhaps "Windows 10 and later" rather than enumerating each version?

[timsneath]

The risk is that some putative future Windows "12" might change the GUID, of course. For safety and conformance with Microsoft's guidance, I copied the sample manifest to the letter: https://docs.microsoft.com/en-us/windows/win32/sysinfo/targeting-your-application-at-windows-8-1
