Unfortunately, still no joy. Also, I have looked through most my TrueImage backup and I don't see any mention of a file by the name of UsoSettings.json. EDIT: One last step I forgot to check done it. My damned firewall was blocking the connection due to a custom rule I had set in ESET labelled "Telemetry?" I followed the list as detailed by @garoto and then saw @andom mention about firewall connections. All good now. Thanks everyone for the assistance!
The following is even simpler: Code: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection] "AllowTelemetry"=dword:00000001 "DisableOneSettingsDownloads"=dword:00000000 Firewall > Allow "mousocoreworker.exe" and "taskhostw.exe" and reboot.
In my case changing only "DisableOneSettingsDownloads" from 1 to 0 did the trick and now the EoS message is finally gone! Edit: and the "culprit" for that as someone else earlier said was indeed the O&O ShutUp 10++ which have the Disable downloading of OneSettings configuration settings (User behavior settings) as recommended to disable.
