Hi, Gareth North. Thank you for your reply. Because I have not upgraded to windows 10 yet I am unsure of the versions. I just assumed when people mention say 1903 that is with the latest updates from Microsoft. My concern is if we can't upgrade windows 10 and keep media center running what are the options ? because I know windows 7 stops receiving updates after January 2020 and so won't be a safe system to run. Surely if we can't update windows 10 with the latest updates that too would be unsafe ? Are we saying I could just stay with 1803 and have no problems ?
