Microsoft will end Extended Support for Windows Server 2016 on January 12, 2027. After this date, there will be no security updates or patches, leaving your systems vulnerable to cyberattacks and compliance risks.
View the Windows Server 2016 Lifecycle.
As a reminder, running unsupported servers can lead to:
- No Security Updates: Unsupported servers will not receive critical patches, leaving them exposed to new vulnerabilities and cyberattacks.
- Compliance Failures: Many regulations require supported software. Using outdated systems can lead to failed audits and fines.
- Vendor Support Ends: Third-party applications and hardware vendors often stop supporting older OS versions, causing compatibility issues.
- Higher Operational Costs: Emergency fixes, downtime, and breach recovery are far more expensive than planned upgrades.
- Increased Risk of Data Breach: Unsupported systems are prime targets for ransomware and other exploits.
While a year may seem like a long way away, it’s important to start planning now to avoid rushed projects as server migrations can take time and need to be handled with care an attention.
