I screwed up and killed a bunch of autostart features - it helped my PC running Windows in a number of ways, however plex no longer auto starts. I just downloaded it and reinstalled but plex doesn’st start and I don’t even remember where it was - registry, services, msconfig, startup folder.
I can manually start plex media server but I’d like to put the entry back if someone knows, please let me know.
Have you tried to simply enable the autostart option from the PMS icon in the system tray? In case it’s already checked… disabling and re-enabling the option might do the trick.
