Aug 10, 2025

Microsoft will officially end support for Windows 10 on October 14, 2025.

🔚 What You Need to Know About the End of Windows 10 Support 

The end of support for a Microsoft operating system (OS) is a critical milestone in its lifecycle. This stage marks the point at which Microsoft ceases to provide updates, patches, and technical assistance for the OS. Understanding this phase is essential for all Windows 10 users and organizations to ensure their systems remain secure and functional. In this post, we will explore the implications of end of support for an OS and why it is crucial for businesses to take proactive measures to safeguard their IT infrastructure. 

Windows 10 was released on July 29, 2015, beginning its lifecycle according to Microsoft’s Modern Lifecycle Policy1. The final iteration, version 22H2, became available on October 18, 2022, with the end of support scheduled for October 14, 20252. Until this date, all editions of Windows 10 will continue to receive monthly security updates.  

The end of support for a Microsoft operating system (OS) is a critical milestone in its lifecycle. This stage marks the point at which Microsoft ceases to provide updates, patches, and technical assistance for the OS. Understanding this phase is essential for users and organizations to ensure their systems remain secure and functional. 

⚠️ What Happens at the End of Support? 

When an OS reaches its end of support, Microsoft stops delivering the following: 

Security Updates 

One of the most critical aspects of the end of support is the discontinuation of security updates. Microsoft stops releasing patches that protect the OS from new vulnerabilities, malware, viruses, and other cyber threats. Without these updates, systems become increasingly susceptible to attacks, which can lead to data breaches, loss of sensitive information, and other security incidents. 

Non-Security Updates 

In addition to security updates, Microsoft also halts non-security updates. These updates typically include bug fixes, performance improvements, and new features that enhance the overall functionality of the OS. Without these updates, users may experience unresolved issues, reduced performance, and a lack of new functionalities that could improve their experience. 

Technical Support 

Technical support from Microsoft is also discontinued at the end of support. This means that users can no longer rely on Microsoft’s assistance for troubleshooting, resolving issues, or answering questions related to the OS. Organizations that depend on Microsoft’s support for maintaining their systems may face challenges in managing and resolving technical problems independently. 

Learnings from running previous Windows versions after the end of support 

Reverse Engineering of Security Updates 

After the end of support, attackers reverse-engineered security updates for supported versions of Windows to find vulnerabilities in Windows XP, leading to increased attacks. 

Persistent Zero-Day Vulnerabilities 

Any newly found software vulnerabilities in Windows XP became perpetual zero-day vulnerabilities, posing significant risks to organizations. 

Post-Retirement Patching Record 

Microsoft had to resurrect Windows XP and Windows Server 2003 to push patches for critical vulnerabilities, highlighting the ongoing security risks even after end of support 

Implications for Users 

The end of support for a Microsoft OS has several significant implications that users and organizations need to be aware of to ensure their systems remain secure and functional. 

Increased Security Risks 

One of the most critical implications is the increased security risks. Without security updates, the OS becomes vulnerable to new threats, including malware, viruses, and other cyber-attacks. These vulnerabilities can lead to data breaches, loss of sensitive information, and other security incidents. Users must be aware that continuing to use an unsupported OS can expose their systems to significant risks. 

Compliance Issues 

Organizations that must adhere to regulatory standards may face compliance challenges if they continue using an unsupported OS. Many regulations require systems to be up-to-date with security patches and updates to ensure the protection of sensitive data. Using an unsupported OS may result in non-compliance, which can lead to legal and financial consequences. 

Compatibility Problems 

As technology evolves, new software and hardware may not be compatible with an outdated OS. This can lead to functionality issues, where users are unable to leverage new technologies or run the latest applications. Compatibility problems can hinder productivity and limit the ability to take advantage of advancements in technology. 

Operational Challenges 

Without technical support from Microsoft, users and organizations may face operational challenges in managing and resolving issues independently. This can be particularly problematic for organizations that rely on Microsoft’s support for maintaining their systems. The lack of support can lead to increased downtime and difficulty in troubleshooting problems. 

Financial Implications 

Continuing to use an unsupported OS can have financial implications. Organizations may need to invest in third-party security solutions to mitigate risks, and the costs associated with non-compliance can be substantial. Additionally, the need to upgrade to a supported OS may require significant financial resources for planning, budgeting, and implementation. 

In summary, the end of support for a Microsoft operating system is a crucial phase that requires careful planning and action to ensure continued security and functionality. Upgrading to a supported OS is the best way to protect systems and data from potential threats.
