Everything Dev Needs to Know About Windows Server 2012 End of Life

Hey Dev, are you aware that Windows Server 2012 has reached its end-of-life (EOL)? If you are running this version of Microsoft’s server operating system, now is the time to start planning for an upgrade. This article will guide you through everything you need to know about the Windows Server 2012 EOL, the risks of running an unsupported server, and the benefits of upgrading to a newer version.

What is Windows Server 2012 EOL?

Windows Server 2012 was released in September 2012, and Microsoft has announced that it will reach end-of-life on October 10, 2023. This means that after this date, Microsoft will stop releasing updates and patches for Windows Server 2012, leaving it vulnerable to security threats and other issues. This will put any business or organization that continues to use this operating system at a significant security risk.

What are the risks of running an unsupported server?

The risks of running an unsupported server are substantial. First and foremost, unsupported servers lack essential security updates, leaving them open to vulnerabilities that hackers can exploit. That means your sensitive company data and confidential information can be accessed by unauthorized parties, leading to a data breach, compliance violations, and financial losses. Additionally, unsupported servers may also fail to integrate with newer hardware and software, making it difficult to maintain their performance level and provide the necessary support to end-users.

What are the benefits of upgrading to a newer version?

Upgrading to a newer version of Windows Server has several advantages. First, it ensures that your business systems are secure and up-to-date with the latest patches and security features, minimizing the risk of data breaches and potential downtime. Second, newer versions of Windows Server often come with improved functionality and performance, such as better virtualization support and enhanced storage capabilities. Finally, running a supported server ensures that your business remains compliant with industry regulations and standards.

Which Versions of Windows Server are Supported?

If you are currently running Windows Server 2012, you need to upgrade to a newer version before the EOL deadline. Microsoft offers several supported versions of Windows Server, including:

Operating System
Release Date
End of Mainstream Support
End of Extended Support
Windows Server 2016

January 11, 2022

January 12, 2027
Azure Stack HCI
March 2020
October 21, 2025
October 21, 2030

What is the difference between mainstream support and extended support?

Mainstream support is the period during which Microsoft provides free updates, security patches, and bug fixes for a product. This period lasts for five years after the product’s release. After the mainstream support ends, extended support begins. During this period, Microsoft provides paid support, security updates, and bug fixes but does not release any new features or enhancements. Extended support lasts for five years and ends with the EOL date.

Can I still use Windows Server 2012 after the EOL date?

Yes, you can continue to use Windows Server 2012 after the EOL date. However, you should be aware that Microsoft will no longer provide any updates, patches, or support for this operating system. That means you will be running an unsupported server, which can expose your business to security risks and compliance issues.

What are the steps for upgrading to a new version of Windows Server?

Upgrading to a new version of Windows Server is a significant project that requires planning, testing, and coordination with your IT team. Here are the steps you should follow:
