What the end of support means
- After the final end date the software keeps running, but the vendor no longer ships fixes or security patches. Known vulnerabilities stay open, and compliance or cyber-insurance requirements may treat it as unsupported software.
- Extended Security Updates (ESU) extends security fixes for a limited time for a fee. Treat it as a bridge to an upgrade.
