Can't Upgrade to Windows 11? How to Keep Your PC Safe and Usable

As October 14, 2025, approaches, marking the end of Windows 10 support, a unique challenge emerges for many users, particularly those relying on second-hand or older computers that don’t meet the hardware requirements for Windows 11. Whether running a small business on a tight budget or using a personal laptop bought gently used, the end of support can’t be ignored.

The question becomes: what options exist when upgrading to Windows 11 isn’t feasible?

Why Does the End of Windows 10 Support Matter to You?

Windows 10 has been a reliable operating system for millions, but without security updates past mid-October 2025, continuing to use it becomes a security risk. Most of these devices lack the Trusted Platform Module (TPM 2.0) or Secure Boot features mandated by Windows 11, making a straightforward upgrade impossible. For many, replacing these laptops with new hardware isn’t an option due to cost, resource constraints, or concerns about electronic waste disposal.

The Security Implications

Without continuing updates, these older systems become vulnerable to malware and intrusions. Hackers particularly target unsupported operating systems, using unpatched vulnerabilities as entry points for ransomware, data theft, and system hijacking. Businesses that use these laptops to manage sensitive customer data or financial information face a particularly high risk of breaches and operational interruptions.

Consider smart alternatives when Windows 11 is not an option.

Don't worry if your hardware can't run Windows 11; you can still have a secure and productive computing experience by exploring these viable alternatives today:

1. Try other supported operating systems.

If hardware restrictions prevent you from upgrading to Windows 11, try another operating system optimised for older PCs:

Using a friendly Linux distro, like AnduinOS, Ubuntu, Zorin OS, Linux Mint, or Solus, are popular and brings new life to older hardware. They are free, actively maintained, and work well on devices with modest specs. Many applications are available as free, open-source alternatives to Windows software, like LibreOffice and OnlyOffice word processors, making this an excellent choice for budget-conscious users.

ChromeOS Flex, which is Google’s lightweight operating system, designed specifically to extend the life of older PCs and Macs. It’s cloud-centric, secure, and simple, ideal for internet-focused tasks.

2. Use a Virtual Desktop Service

If you need to retain specialised software or Windows environments, cloud-based virtual desktops allow users to access Windows 11 on an old device by streaming it over the internet. This approach keeps hardware refresh costs low while maintaining security and software compatibility. But if you would like to cut costs entirely, you can repurpose your older laptop or desktop by setting up an open-source virtualisation platform like Proxmox server.

This option gives you the benefit of running multiple virtual machines locally or remotely, offering a customisable, cost-effective way to maintain modern OS environments on legacy hardware. Additionally, using platforms like Proxmox helps extend the life of your older computers, reducing the need to discard them and thereby cutting down on electronic waste.

3. Enrol in the Extended Security Updates (ESU) Program

Microsoft Extended Security Updates (ESU) is a paid program that extends Windows 10 security patches until October 2026. To be eligible for this program, your computer must be running Windows 10 version 22H2.

If you are using an enterprise version of Windows 10 for your business, you can acquire the licenses via the Microsoft Volume Licensing Program at a cost of $61 USD per device for the first year. Subsequently, the price will double each consecutive year, with a maximum duration of three years.

However, if you reside in the European Economic Area (EEA), these updates are free for an additional year, provided you sign in with a Microsoft account. It is important to note that this program is a potential short-term safety net while you consider longer-term choices.

4. Consider Hardware Upgrades Where Possible

If your computer was built with right-to-repair principles in mind, you can purchase and install a Windows 11-compatible motherboard along with all necessary components, such as a supported processor, TPM 2.0, and sufficient RAM. This upgrade can breathe new life into your device by meeting Windows 11 hardware requirements and allowing for a smooth transition to the newest operating system. However, it’s important to note that in some cases, the combined cost of a motherboard, processor, and other parts may approach or exceed the price of a new computer, making a full replacement a more economical and practical choice.

5. Continue using Windows 10 as it currently stands (Not Recommended)

Ignoring the deadline and sticking with your current Windows 10 version is technically possible but highly risky. Without security updates, your systems will remain exposed to new threats. If you go this route, beefing up security with third-party security tools and limiting network exposure is a necessary step, but it is not a long-term solution.

This transition might seem daunting at first, but with thoughtful planning and the right guidance, it presents an opportunity to upgrade not only your operating system but also your skills by learning how to apply new technologies to your portfolio.
