What end of support means
- /Microsoft stops releasing security updates and fixes. Vulnerabilities discovered after that date stay open for good.
- /Nothing switches off on that day. That is exactly why it is easy to put off, and why an unsupported system becomes an easier target every month.
- /Insurers, auditors and large customers increasingly ask whether you run unsupported systems.
