What will happen if I’m still using Windows Server 2012 R2 after the 10th Of October 2023?

If you are still using Windows Server 2012 R2 after the 10th October 2023, it will no longer be supported by Microsoft. This means that Microsoft will no longer provide security updates or technical support for the operating system.

This can leave your server and network vulnerable to security threats and vulnerabilities, as well as any compatibility issues with newer software and hardware.

Additionally, your organization will not comply with regulatory requirements such as PCI-DSS which requires to have all the systems updated and secure.

To break it down into bullet points you could face issues such as:

Security vulnerabilities: Microsoft will no longer release security updates for out-of-date versions of Windows Server, leaving your server and network vulnerable to security threats and vulnerabilities.

Compliance issues: Many regulatory requirements such as PCI-DSS, HIPAA, and SOX require that systems are kept up to date and secure, using an out-of-date version of Windows Server could put your organization out of compliance.

Lack of technical support: Microsoft will no longer provide technical support for out-of-date versions of Windows Server, which can make it difficult to troubleshoot and resolve technical issues.

• Compatibility issues: Out-of-date versions of Windows Server may not be compatible with newer software and hardware, which can make it difficult to run or maintain applications on the server.

Limited functionality: Out-of-date versions of Windows Server may not include features and functionality found in newer versions, which can limit the capabilities of your network and servers.

What to do if you are still using Windows Server 2012 R2?
