OK, aside from the fact that builds 143-28/32/42 won't even install in my UEFI desktop unless I disable secure-boot first (installs either lock up or simply revert to 14316 if attempted with secure-boot on), once I get 14342 installed and try to install Feedback @ Settings/System/Apps & Features/Manage Optional Features/Add a Feature...the build tells me there are no optional features available for installation! Meaning, with yet another build, I am unable to supply Feedback.
Comments appreciated...
