How to Prepare for Windows 10 End of Life (October 2025)

As Microsoft officially sunsets support for Windows 10 in October 2025, organizations and individual users alike must begin planning their transition to a newer version of Windows. Without proper preparation, businesses may find themselves running unsupported systems lacking important security updates and technical support. The shift from Windows 10 to Windows 11—or another future release—presents not only an opportunity to upgrade features but also a need to evaluate system requirements, ensure hardware meets the minimum standards, and consider participation in the Extended Security Updates (ESU) program if upgrades are delayed. 

Upgrading to Windows is more than just a software refresh—it’s a strategic move that impacts web browsing performance, settings update security, and overall IT infrastructure. Many existing Windows PCs, especially those without a Trusted Platform Module (TPM) 2.0 chip, may not meet the hardware requirements for the latest operating system, necessitating new device purchases or adjustments to deployment plans. Organizations must assess which systems support the new version of Windows and ensure settings update security via Windows Update is streamlined and protected. 

This transition to Windows also introduces features like Copilot PCs and enhanced security features that offer long-term value but may require user training and configuration updates. Taking early action allows businesses to avoid disruptions, maintain compliance, and fully leverage Microsoft’s latest innovations. In this article, we’ll outline key steps to help you prepare, from evaluating your devices to managing updates and aligning your strategy with Microsoft’s roadmap for continued support for Windows. 

Evaluate Your Current Environment and System Requirements 

The first step in preparing for the end of support for Windows 10 is to conduct a thorough assessment of your current IT environment. Take inventory of all Windows PCs in use and determine whether each device meets the minimum hardware requirements for the next version of Windows. Microsoft has raised the baseline specifications for Windows 11, including the need for a Trusted Platform Module (TPM) 2.0, specific processor generations, and increased memory and storage thresholds. Many older machines may fall short, making them ineligible for a direct upgrade. 

This is also a good time to review which machines are critical to business operations and may require enhanced security features. Devices that no longer receive important security updates could become liabilities in your network, particularly those used for tasks involving web browsing, customer data, or financial transactions. Ensuring support for Windows 11 or other future versions will minimize these risks. 

In cases where systems do not meet requirements, you may consider replacing outdated hardware or enrolling in Microsoft’s Extended Security Updates (ESU) program as a temporary bridge. While ESUs offer a short-term safety net, they are not a substitute for long-term modernization. Proactively aligning your hardware strategy with the new operating system’s demands helps ensure a smooth transition to Windows and positions your organization to take advantage of upcoming technologies like Copilot PCs. 

Plan Your Upgrade and Deployment Strategy 

Once you’ve identified which devices support the new version of Windows, it’s time to create a structured upgrade and deployment plan. Upgrading to Windows isn’t just about installing a new operating system—it’s about minimizing downtime, preserving user data, and ensuring compatibility with your existing applications and infrastructure. For businesses, a phased rollout is often the most efficient method, allowing IT teams to test the upgrade process on a small group of systems before wider deployment. 

Start by backing up all critical data and confirming that essential software is compatible with the new OS. Pay special attention to legacy applications and line-of-business tools, as some may require updates or replacements. If you use system management platforms like Microsoft Endpoint Manager or Windows Autopilot, now is the time to configure them for the transition to Windows 11 or beyond. 

During this process, ensure that all settings, updates and security Windows configurations are reviewed and aligned with Microsoft’s best practices. Windows Update policies should be optimized to allow for timely delivery of patches and features, especially those related to enhanced security features. Organizations that manage remote or hybrid users will also want to verify that mobile device policies are enforced consistently across all endpoints. 

By developing a comprehensive upgrade strategy, you’ll ensure your transition to Windows is seamless and secure, paving the way for improved performance, better user experience, and long-term support for Windows PCs throughout your organization. 

Address Security Gaps and Consider ESU Options 

As the October 2025 deadline approaches, one of the most critical areas to focus on is security. Once Windows 10 reaches end of life, devices running the outdated operating system will no longer receive important security updates, leaving them vulnerable to emerging threats. This gap can expose sensitive data, disrupt operations, and increase the likelihood of compliance violations—especially for organizations in regulated industries. 

If immediate upgrading isn’t feasible for all systems, Microsoft’s Extended Security Updates (ESU) program offers a temporary solution. The ESU program provides critical security patches for a limited time after official support ends. While this can extend protection, it should be viewed as a short-term bridge—not a long-term strategy. Participating in the ESU program buys valuable time, but it also incurs additional costs and doesn’t include technical support or new feature updates. 

Security settings should be thoroughly reviewed and tightened during the transition to Windows. Use this opportunity to standardize settings update security Windows configurations, ensuring encryption, antivirus, and firewall protections are enabled across all devices. Organizations should also explore modern security features available in newer operating systems, such as hardware-based isolation, improved identity protections, and threat detection tools powered by AI—especially beneficial when moving to platforms like Copilot PCs. 

Support User Adoption with Training and Change Management 

Transitioning from Windows 10 to a newer version of Windows affects more than just hardware and technical infrastructure—it also impacts end users. A successful upgrade depends on user readiness and the ability to adapt to interface changes, new workflows, and enhanced security features. To minimize disruption and support productivity, organizations should implement a clear change management plan that includes training, communication, and user support. 

Start by identifying changes in the operating system that may affect day-to-day tasks. For example, Windows 11 introduces a redesigned Start Menu, taskbar behavior, and integration with features like Microsoft Copilot. Providing short, role-specific training sessions or video tutorials can help users become familiar with these updates and avoid confusion. Involving department heads or internal champions early in the process can also help reinforce adoption and ensure that key tools and processes are working as expected after the upgrade. 

It’s equally important to establish support channels during the transition to Windows. This includes preparing helpdesk staff for common questions, creating internal documentation for frequently updated settings, and ensuring that IT teams are equipped to troubleshoot compatibility issues. Updating policies to reflect the new operating environment—especially in terms of device usage, security, and web browsing standards—will reinforce consistency and reduce risks tied to user behavior. 

Future-Proof Your Environment with Modern Devices and IT Planning 

As you transition to a newer version of Windows, it’s also the perfect time to future-proof your IT environment. Investing in modern devices that meet the minimum hardware requirements not only ensures compatibility with the latest operating system but also positions your organization to take advantage of new innovations, such as AI-powered productivity tools, advanced endpoint protections, and Copilot PCs designed for hybrid work scenarios. 

When selecting new hardware, look for systems optimized for enhanced security features and long-term support for Windows updates. Devices with built-in Trusted Platform Modules (TPM 2.0), support for virtualization-based security, and firmware protections offer a stronger baseline for secure computing. Standardizing hardware across the organization can also simplify maintenance and reduce troubleshooting complexity. 

Additionally, align your IT roadmap with Microsoft’s release cycles and support timelines to avoid future end-of-life scrambles. Regularly revisiting your inventory, evaluating software dependencies, and scheduling routine upgrades will help maintain a secure and productive environment. Taking advantage of tools like Windows Update for Business and leveraging cloud-based management solutions can further streamline system maintenance and improve visibility across your device fleet. 

Preparing now ensures you won’t just be ready for the Windows 10 end of life—you’ll be ahead of it, with an infrastructure designed to support innovation, scalability, and security well into the future.
