Which Windows Server Version is Most Used?

Windows Server has been a dominant force in enterprise IT environments for decades. With multiple versions available, businesses often wonder which version is the most widely used and why. While the exact popularity of each version depends on factors like industry, company size, and specific IT needs, we can analyze usage trends and determine the most commonly deployed version.

Current Most Used Windows Server Version

As of 2025, Windows Server 2019 remains the most widely used version. It strikes the perfect balance between stability, security, and modern features. However, Windows Server 2022 is gaining traction, especially among organizations prioritizing long-term support and cloud integration.

Why is Windows Server 2019 So Popular?

Long-Term Support (LTS) – Windows Server 2019 is part of Microsoft’s Long-Term Servicing Channel (LTSC), meaning it receives regular security updates and support for an extended period.
Proven Stability – Many organizations prefer stability over the latest features, and Windows Server 2019 has had years of refinement and bug fixes.
Hybrid Cloud Capabilities – It offers seamless integration with Azure, making it ideal for businesses transitioning to hybrid cloud environments.
Application Compatibility – Many enterprise applications and services are optimized for Windows Server 2019, reducing the risk of compatibility issues.
Performance and Security – Features like Windows Defender ATP, Shielded Virtual Machines, and improved networking capabilities make it a secure and efficient choice.

What About Windows Server 2022?

Windows Server 2022 is the latest release, and while its adoption is growing, many businesses are waiting for broader industry adoption before upgrading. It introduces enhancements in:

Security (Secured-core server, TLS 1.3 enforcement)
Hybrid Cloud (Better Azure integration, improved Windows Admin Center)
Performance (Support for larger memory and CPU configurations)

Windows Server 2016 and Older Versions

Although Windows Server 2016 still has a presence in enterprise environments, many organizations are migrating away due to its nearing end of mainstream support. Older versions like Windows Server 2012 R2 and Windows Server 2008 R2 are rapidly being phased out, as they no longer receive security updates unless covered under extended support agreements.

Conclusion: Should You Upgrade?

If your organization is still running Windows Server 2016 or earlier, it's advisable to consider upgrading to Windows Server 2019 or 2022. While Windows Server 2019 remains the most widely used due to its stability and support, Windows Server 2022 is quickly becoming the go-to choice for businesses looking to future-proof their IT infrastructure.

For organizations heavily leveraging Azure and cloud-based services, Windows Server 2022 is a strong contender. However, if stability and proven performance are your top priorities, Windows Server 2019 is still the safest bet.
