On June 13, when the June 2023 security update lands, the Windows 10 21H2 Home, Pro, Pro Education, and Pro Workstation editions will lose servicing and support, meaning they will stop receiving security and preview updates to protect against security threats.
Even if you’re happy to keep using Windows 10 21H2, Microsoft will be updating consumer and non-managed business devices at the end of servicing to 22H2 automatically. There’s no word when this upgrade will take place.
