Microsoft says the best way to get Windows 11 is either to upgrade your existing PC to the new software, which should be available as a free download to millions, or to buy a new computer altogether.

Many Windows 10 users resent the idea of buying a new machine when they consider their current hardware working well. The only way to continue to receive security updates on Windows 10 after 14 October 2025 will be to pay for Microsoft's premium Extended Security Updates, which will cost consumers $30 (£24) per year.

Microsoft has published what it considers the minimum system requirements for WIndows 11. You can check that out here, and then see if your Windows 10 PC is deemed speedy enough to be able to run Windows 11. It likely will be compatible if it has a TPM 2.0 chip, a security chip generally required for Windows 11 to run smoothly.

But as spotted by Tom’s Guide, Microsoft has updated a page on its website that confirms you will be able to update your device to Windows 11 even if it does not meet the system requirements. Microsoft does not appear to intend to block updates even if you’re running lower-powered or aging hardware, though the firm does caveat that with some stern warnings.

“Installing Windows 11 on a device that doesn't meet Windows 11 minimum system requirements isn't recommended. If Windows 11 is installed on ineligible hardware, you should be comfortable assuming the risk of running into compatibility issues,” Microsoft said.

“A device might malfunction due to these compatibility or other issues. Devices that don't meet these system requirements aren't guaranteed to receive updates, including but not limited to security updates.”

A disclaimer that may appear on affected PCs at the installation stage states that installing Windows 11 on an incompatible PC “may result in compatibility issues”, and will ask users to accept the terms manually before proceeding.

A watermark will also be added to the Windows 11 desktop on devices that install it but don’t technically meet the minimum system requirements. Microsoft implies those affected will be able to revert back to Windows 10 if they encounter issues by going to Settings > System > Recovery, and selecting Go back under the Recovery options.

You may have to make a decision on this in the near future. Microsoft recently started prompting Windows 10 users with full screen alerts that urge users to move to Windows 11 or miss out on the “ultimate experience”. Part of its advice is to purchase a new device.
