The end of support for Windows 10 is fast approaching—October 14, 2025 marks the final day Microsoft will provide technical assistance, feature updates, and security patches for the operating system. While many organizations have already begun transitioning to Windows 11, recent data shows just nearly 45% of users are still running Windows 10, leaving a significant portion of businesses exposed to potential risks.
Why This Matters for Businesses
Running on unsupported software poses serious security and compliance risks. Once support ends, Windows 10 devices will no longer receive Microsoft’s weekly security updates, making them vulnerable to cyberattacks. These vulnerabilities become public knowledge with each ESU update, meaning unpatched systems are easy targets.
For businesses in regulated industries—such as healthcare, finance, legal, and education—remaining on unsupported systems can lead to non-compliance, fines, and reputational damage.
Business Options for Staying Supported
Microsoft offers several paths forward for organizations still using Windows 10:
Upgrade to Windows 11
Migrating to Windows 11 is the most secure and future-proof option. It supports the latest Microsoft business apps, offers enhanced security features, and ensures long-term compatibility. Upgrading now helps businesses avoid ESU licensing fees and ensures a smoother transition.
Adopt Cloud PCs
Businesses using Windows 365 Cloud PCs or other Azure-based virtual machines are eligible for free Extended Security Updates (ESU) for Windows 10. This includes:
- Windows 365
- Azure Virtual Desktop
- Azure VMs and Dedicated Hosts
- Azure VMware Solution
- Nutanix Cloud Clusters on Azure
- Azure Stack Hub, Edge, and Local
Cloud-based PCs provide businesses with secure remote access, centralized data management, and built-in compliance features, making them an ideal solution for organizations seeking agility during their Windows 11 transition.
Purchase ESU Licenses
For businesses not using Cloud PCs, Microsoft offers paid ESU licenses:
Year 1: $61 per device
Year 2: $122 per device
Year 3: $244 per device
If a business delays enrollment, cumulative fees apply. For example, enrolling in Year 2 costs $183 (Year 1 + Year 2), and enrolling in Year 3 costs $427 (all three years combined).
This option provides breathing room for organizations to plan their transition without rushing, but it’s a temporary solution because all ESU support ends in 2028.
The Business Risks of Unsupported Windows 10: Why Staying Current Matters
Even with other cybersecurity measures in place, unpatched systems are inherently vulnerable. Microsoft’s weekly updates fix bugs and patch security holes—without them, your network is exposed. This means that with the end of security support coming up for Windows 10, they will no longer be patching new known vulnerabilities.
For businesses, staying supported from a security perspective is not optional…it’s essential. This support is critical for:
- Protecting sensitive data
- Maintaining regulatory compliance
- Avoiding operational disruptions
- Ensuring compatibility with Microsoft business apps
