  • Household sharing limits reached for Windows

Fix steps

FIX
  1. Shut everything down, wait one minute, bring the modem/router online first, then the TV, then Windows.
  2. Install available Windows updates over Ethernet if Wi‑Fi is weak, then relaunch.
  3. Sign out of Windows on the TV, clear cache, power-cycle once, then sign in again.
  4. Reserve a DHCP lease for the TV, reboot network gear, and try Windows again.
