forced origin to close via task manager, restarted origin removed the checkbox from start with windows, closed origin,
opened services.msc (went to start bar /admin/tools>services) scrolled down to ssdp and enabled that, then enabled upnp discovery, opened network sharing center >advanced sharing>checked network discovery on,
restarrted the pc, went and made a brew, came back right clicked origin on the desktop and removed the start as admin option from compatability tab in properties, started origin and it was just showing up again.
hopefully that was all easy enough to understand, but if not then i'll try and recreate the problem and log each process wiht screenshots in the future, although i suspect your pc knowledge is probably higher than mine
