Windows 10 support is ending. Windows 10 has been a reliable operating system for many users since its release in 2015. Like all software, it has a lifecycle, and Microsoft has announced that Windows 10 will reach its end of life on October 14, 2025. This means that after this date, Microsoft will no longer provide technical support, feature updates, or security updates for Windows 10. In this blog post, I’ll discuss what this means for users and what you can do to prepare for the transition.
What does end of lifecycle mean?
When an operating system reaches the end of its lifecycle, it means that the developer, in this case Microsoft, will no longer release updates or provide support for the product. This includes the following:
- Technical support: No more assistance from Microsoft in troubleshooting issues.
- Feature updates: No new features or improvements will be added.
- Security updates: No more fixes for vulnerabilities that could compromise the system.
Why should you care?
Security is a major concern for discontinued software. Without security updates, your system is more vulnerable to malware, viruses, and other cyber threats. Additionally, you won’t be able to use the latest features and improvements of newer operating systems, which can affect productivity and user experience.
What are your options?
- Upgrade to Windows 11: If your computer meets the hardware requirements, you can upgrade your operating system to Windows 11 for free. If your company uses Intune device management, you can use its features for the upgrade. Windows 11 can also be upgraded for free through Windows Update if no other technologies are in use. Windows 11 offers improved security, performance, and new features. Deploying Windows 11 with Intune is incredibly straightforward and efficient. With Intune’s cloud-based management platform, IT administrators can seamlessly configure, manage, and deploy Windows 11 across all devices in the organization. Thanks to its user-friendly interface and robust automation capabilities, Intune simplifies the entire deployment process from initial setup to ongoing management. Features like Autopilot enable zero-touch provisioning, ensuring new devices are ready to use right out of the box. Additionally, Intune’s integration with other Microsoft services ensures a unified and secure environment, making the transition to Windows 11 smooth and effortless.
- New hardware: If your organization’s current devices don’t meet Windows 11 requirements, you’ll need to replace the hardware. Many retailers and PC manufacturers offer trade-in programs for old devices; it’s worth discussing these with your hardware supplier.
- Extend Security Updates (ESU) program: If upgrading the Windows 10 operating system is not currently possible in your company for some reason, you can join Microsoft’s Extend Security Updates (ESU) program. The program is paid, currently $61 / device / year, and the cost doubles every year. However, with this program, it’s possible to extend the lifecycle of Windows 10 devices for 3 years. More information about the program can be found at the link: Extended Security Updates (ESU) program for Windows 10 | Microsoft Learn
Continue using Windows 10 with caution: If you decide to continue using Windows 10, which is not recommended at all, remember to back up your data regularly and protect your system from external security threats by other means. In this case, you should also consider placing devices in a closed network to prevent vulnerabilities from being exploited from the outside world. A closed network, of course, may bring other challenges in terms of usability.
Impact on Microsoft 365 Office tools
If you use Microsoft 365 (formerly Office 365) tools such as Word, Excel, PowerPoint, and Outlook, it’s important to note that these tools will continue to work in Windows 10 even after its end of life. However, there are some aspects to keep in mind:
- Security risks: Using Microsoft 365 applications on an unsupported operating system can pose security risks. Without Windows 10 security updates, your system and data may be vulnerable to cyber threats.
- Compatibility: Over time, new updates to Microsoft 365 applications may become incompatible with older operating systems like Windows 10. This can lead to degraded functionality or even inability to use certain features.
- Support: Support for Microsoft 365 subscribers may be limited when applications are used on an unsupported operating system. Microsoft may prioritize support for users of supported operating systems, such as Windows 11.
To ensure the best performance and protection, it is highly recommended to upgrade to Windows 11 if your computer meets the requirements. This way, you can continue to enjoy all the benefits of Microsoft 365 without the associated risks of using it on an unsupported operating system.
Windows 10 devices in Finland
According to the latest information, up to about 2.5 million devices in Finland still have the Windows 10 operating system, including both business and personal devices. This highlights the importance of the upcoming transition and the need to prepare for the end of life of this operating system. It’s not too late to act, but I recommend starting the transition project immediately, as we know time tends to pass very quickly in the hourglass.
How to prepare for the transition
- Back up your data: Make sure all your important files, photos, and documents are backed up to an external drive or cloud storage service like OneDrive.
- Check compatibility: Use the Windows 11 compatibility tool to see if Windows 11 will work on your current computer. You can download the PC Health Check app here.
- Plan the upgrade: Decide whether you want to upgrade to Windows 11, buy a new computer, or switch to an alternative operating system. Make a plan and set a schedule for the transition.
- Stay informed: Keep an eye on Microsoft’s official announcements and updates regarding the end of life for Windows 10 and the transition to Windows 11.
- If your company’s own resources are not sufficient to carry out the project, contact a trusted service provider with experience in Windows 11 deployments. In this matter, the consiglieri of AboveIT Oy can assist your organization.
