Microsoft Extends M365 App Support on Windows 10: What You Need to Know

Microsoft Extends M365 App Support on Windows 10: What You Need to Know

Microsoft has made a significant announcement for users still running Windows 10: security updates and support for Microsoft 365 (M365) applications will continue until October 2028. This extension provides a safety net for those not yet ready or able to migrate to Windows 11, but it comes with important considerations.

Continued Security for M365 Apps

The core message is clear: if you're a Microsoft 365 subscriber using Windows 10, you'll receive security patches for your familiar applications like Word, Excel, and PowerPoint through the usual channels until October 10, 2028. This is welcome news, especially given the looming end-of-support date for Windows 10 itself.

The Windows 10 End-of-Life Context

Windows 10's official end-of-life is October 14, 2024. After this date, Microsoft will no longer provide free security updates for the operating system. Users who wish to continue receiving updates will need to purchase an Extended Security Update (ESU) license, incurring additional costs.

Support Caveats and the Push to Windows 11

While the extended M365 app support is beneficial, it's not without strings attached. Microsoft is clearly incentivizing users to upgrade to Windows 11. Here's what you need to know about the support limitations:

  • Windows 11 as the Baseline: If you encounter an issue with M365 apps on Windows 10, Microsoft support will first determine if the problem exists on Windows 11.
  • Upgrade Recommendation: If the issue is specific to Windows 10, Microsoft will strongly recommend upgrading to Windows 11.
  • Limited Troubleshooting: If upgrading to Windows 11 isn't feasible, Microsoft will offer troubleshooting assistance, but technical workarounds may be limited or unavailable.
  • No Bug Fixes or Product Updates: Support incidents for M365 apps on Windows 10 will not include the option to log bugs or request product updates. This means you're essentially receiving security patches, but not new features or fixes for non-security-related issues.

Why the Hesitation to Upgrade?

Despite Microsoft's push, many users remain on Windows 10. Several factors contribute to this reluctance:

  • Hardware Requirements: Windows 11 has stricter hardware requirements than Windows 10, particularly regarding the processor, TPM (Trusted Platform Module), and boot method (UEFI). Many older machines that run Windows 10 perfectly well are not compatible with Windows 11.
  • Cost of New Hardware: Upgrading to Windows 11 may necessitate purchasing new computers, which can be a significant expense, especially for businesses with numerous devices.
  • User Interface Changes: Some users dislike the changes to the user interface in Windows 11, preferring the familiar look and feel of Windows 10.
  • Perceived Lack of Benefit: Some users don't see a compelling reason to upgrade, feeling that Windows 11 doesn't offer enough new features or improvements to justify the effort and potential cost.

The Surface Issue

The hardware incompatibility issue is particularly frustrating for owners of older Surface devices. Many Surface Books, Surface Pros, Surface Laptops and Surface Studios are not compatible with Windows 11, despite being relatively high-end devices when released.

Market Share Realities

The continued popularity of Windows 10 is reflected in market share data. According to Statcounter, Windows 10 still holds a significant portion of the Windows desktop market, surpassing Windows 11. This indicates that a large number of users are either unable or unwilling to upgrade.

Implications for Businesses

The extended M365 app support has significant implications for businesses:

  • Breathing Room: It provides more time to plan and execute a Windows 11 migration strategy.
  • Cost Management: It allows businesses to defer hardware upgrades, potentially saving money in the short term.
  • Security Considerations: While M365 apps will be secured, the underlying Windows 10 operating system will become increasingly vulnerable without ESU licenses.
  • Compatibility Testing: Businesses need to test their applications and workflows on Windows 11 to ensure compatibility before migrating.
  • Support Planning: IT departments need to be aware of the support limitations for M365 apps on Windows 10 and factor this into their support strategies.

Recommendations

Given the situation, here are some recommendations for Windows 10 users:

  • Assess Hardware Compatibility: Determine which of your devices are compatible with Windows 11.
  • Evaluate Upgrade Costs: Calculate the cost of upgrading hardware versus purchasing ESU licenses for Windows 10.
  • Plan Your Migration: Develop a detailed plan for migrating to Windows 11, including timelines, testing, and user training.
  • Consider ESU: If upgrading to Windows 11 is not immediately feasible, consider purchasing ESU licenses to maintain security for Windows 10.
  • Stay Informed: Keep up-to-date with Microsoft's announcements and recommendations regarding Windows 10 and Windows 11.

The Bottom Line

Microsoft's decision to extend M365 app support on Windows 10 is a pragmatic one, acknowledging the realities of hardware limitations and user preferences. However, it's crucial to understand the support caveats and plan accordingly. The long-term goal should still be to migrate to Windows 11, but this extension provides valuable time to do so strategically.

Windows 10: A Look Back

Windows 10 was released in July 2015 and was initially offered as a free upgrade to users of Windows 7 and Windows 8.1. It was positioned as the "last version of Windows," with Microsoft planning to deliver ongoing feature updates rather than releasing entirely new versions. However, this strategy changed with the introduction of Windows 11 in 2021.

Key Features of Windows 10

  • Cortana: Microsoft's virtual assistant, integrated into the operating system.
  • Microsoft Edge: The successor to Internet Explorer, designed to be a faster and more modern web browser.
  • Universal Apps: Apps that could run on multiple devices, including PCs, tablets, and smartphones.
  • DirectX 12: A new version of Microsoft's graphics API, offering improved performance for games and other graphics-intensive applications.
  • Windows Hello: A biometric authentication system that allowed users to log in using facial recognition or fingerprint scanning.

The Legacy of Windows 10

Windows 10 has been a successful and widely adopted operating system. It is known for its stability, compatibility, and user-friendly interface. While Windows 11 is now the latest version of Windows, Windows 10 will continue to be supported for several years to come, providing a reliable platform for millions of users.

The Future of Windows

Microsoft is committed to the Windows platform and continues to invest in its development. Windows 11 introduces a redesigned user interface, improved performance, and new features such as Snap Layouts and Microsoft Teams integration. As technology evolves, Windows will continue to adapt and provide a platform for innovation and productivity.

Extended Security Updates (ESU) Program

For users who need to continue running Windows 10 after the end-of-life date, Microsoft offers the Extended Security Updates (ESU) program. This program provides security updates for up to three years, allowing organizations to maintain security while they plan their migration to a newer operating system.

How ESU Works

  • Annual Subscription: ESU is offered as an annual subscription, with the price increasing each year.
  • Specific Devices: ESU licenses are assigned to specific devices, allowing organizations to choose which machines to protect.
  • Security Updates Only: ESU provides security updates only, not new features or non-security-related fixes.
  • Volume Licensing: ESU is typically purchased through Microsoft's volume licensing programs.

Alternatives to Windows 11

While Windows 11 is the recommended upgrade path, there are alternative operating systems that users may consider:

  • Linux: A free and open-source operating system that offers a high degree of customization and security.
  • macOS: Apple's operating system, available only on Apple hardware.
  • ChromeOS: Google's operating system, designed for web-based applications and cloud computing.

Choosing the Right Operating System

The choice of operating system depends on individual needs and preferences. Factors to consider include hardware compatibility, software compatibility, security requirements, and budget.

Conclusion

Microsoft's extended support for M365 apps on Windows 10 provides a valuable safety net for users who are not yet ready to upgrade to Windows 11. However, it's important to understand the support limitations and plan accordingly. Whether you choose to migrate to Windows 11, purchase ESU licenses, or explore alternative operating systems, the key is to make an informed decision that meets your specific needs.
