Windows 11 Adoption: 72% Share & Windows 10 Decline

The share of Windows 11 installations has reached 72%, according to recent data, signaling a continued, though not universally welcomed, shift away from Windows 10. Even as this marks a significant milestone for Microsoft’s latest operating system, the transition isn’t being driven by widespread user enthusiasm. Instead, it’s largely a consequence of the impending conclude of support for Windows 10, stricter hardware requirements for Windows 11, and a series of updates to Windows 10 that some users have found problematic.

The End of an Era for Windows 10

Windows 10, released in 2015, enjoyed a long and successful run, becoming one of the most widely adopted operating systems in history. Microsoft initially promised free upgrades for life, fostering a large user base. However, support for most versions of Windows 10 is now ending. Specifically, Microsoft ended support for Windows 10 version 22H2 on October 14, 2025. Microsoft Learn details the lifecycle of Windows versions, and the end of support means no further security updates, leaving systems vulnerable to emerging threats. This looming deadline is a primary driver behind the increase in Windows 11 adoption, as users and organizations seek to maintain security, and compatibility.

Hardware Requirements and the Upgrade Path

The move to Windows 11 isn’t seamless for everyone. Microsoft implemented stricter hardware requirements for Windows 11, including a requirement for a Trusted Platform Module (TPM) 2.0 security chip and specific processor generations. This effectively excluded a significant number of older PCs from being able to upgrade, creating frustration among users with perfectly functional hardware. While workarounds exist, they are not officially supported and may introduce instability. The requirement for TPM 2.0, a cryptographic processor, is intended to enhance security by providing hardware-based protection for encryption keys and other sensitive data. However, it also adds a layer of complexity and cost for users who demand to upgrade their hardware.

Patching Problems and User Sentiment

The transition hasn’t been without its hiccups. Recent reports indicate that some Windows 10 updates have introduced issues, further pushing users towards Windows 11 as a more stable alternative. A Reddit thread highlighted issues with recent Microsoft updates, though the problems appeared to be isolated to Windows 10/11 Enterprise editions. Reddit users reported problems, and Microsoft responded with emergency updates to address the issues. This pattern of problematic patches has contributed to a sense of unease among some users, making the prospect of a fresh start with Windows 11 more appealing, despite the hardware requirements and learning curve.

Security Concerns and the Importance of Updates

The urgency to upgrade is also fueled by growing cybersecurity threats. Forbes reported on CISA warnings to patch Microsoft Windows vulnerabilities, emphasizing the critical need for users to maintain their systems updated. Outdated software is a prime target for attackers, and the end of support for Windows 10 versions means those systems will become increasingly vulnerable over time. Microsoft regularly releases security updates to address newly discovered vulnerabilities, and installing these updates is essential for protecting against malware and other threats. The two-week security deadline highlighted by CISA underscores the severity of some vulnerabilities and the importance of prompt patching.

Understanding the Long-Term Servicing Channel (LTSC)

Windows Server 2025, Microsoft’s latest Long-Term Servicing Channel (LTSC) release, offers a different approach to updates. As detailed on Microsoft Learn, LTSC releases prioritize stability and security with a focus on long-term support. This contrasts with the more frequent feature updates delivered through the standard Windows release cycle. Windows Server 2025 is available as an optional update for Windows Server 2022 and 2019, allowing organizations to upgrade at their own pace. The LTSC model is particularly attractive to businesses and organizations that require a stable and predictable operating environment.

What Comes Next: A Gradual Transition and Ongoing Support

The transition to Windows 11 is expected to continue gradually over the next few years, driven by the end of support for Windows 10 and the increasing availability of compatible hardware. Microsoft will likely continue to offer incentives and promotions to encourage users to upgrade. Microsoft will continue to release feature updates and security patches for Windows 11, enhancing its functionality and addressing emerging threats. For organizations, careful planning and testing are crucial to ensure a smooth transition to Windows 11, minimizing disruption and maximizing compatibility with existing applications and infrastructure. The Windows Updates API in Microsoft Graph provides a programmatic way for IT administrators to stay informed about Windows update status and known issues.

Looking ahead, the focus will be on refining the Windows 11 experience, addressing user feedback, and ensuring a secure and reliable operating environment. Microsoft’s commitment to ongoing development and support will be key to maintaining user confidence and driving further adoption of Windows 11.
