Microsoft Get Windows 10 Free? What You Need to Know

Updated 5 November 2026 · Standard formula, shown below

Yes—Microsoft offered Windows 10 as a free upgrade to eligible computers running genuine Windows 7 or Windows 8.1 during its original limited-time offer, and qualifying Windows 10 devices can still be reinstalled without paying again. However, the free-upgrade period has ended, Windows 10 support has ended, and a new installation does not automatically give every computer a free licence.

How the free Windows 10 upgrade worked

Microsoft launched Windows 10 in 2015 and promoted a free upgrade for most users of genuine Windows 7 and Windows 8.1 editions. The offer was available for a limited period, officially ending on July 29, 2016. It was intended to move eligible existing PCs to Windows 10, not to provide a free copy for any computer or for people who had no qualifying Windows licence.

During the offer, users could upgrade through Windows Update or Microsoft’s installation tools. Activation generally established a digital licence associated with the upgraded device. Once activated, the same device could usually have Windows 10 reinstalled later and reactivate online, provided its hardware and edition remained eligible. A major hardware change, such as replacing the motherboard, could affect activation.

Microsoft later continued to allow many Windows 7 and 8.1 product keys to activate Windows 10 installations. That behavior was not a promise that the original free offer remained open indefinitely. Microsoft’s current guidance and activation systems may change, so an old key should not be treated as a guaranteed way to obtain a new free licence today.

Can you get Windows 10 free now?

It depends on whether the computer already has a valid Windows entitlement. If Windows 10 was previously activated on that PC, reinstalling the same edition on the same device will generally reactivate when the computer connects to the internet. During setup, you can select the option indicating that you do not have a product key; activation can occur later if the device has a matching digital licence.

A computer that has never had an activated Windows licence is different. Downloading Microsoft’s installation media is free, but the download itself is not a licence. Installing Windows without a valid entitlement does not make the software legitimately activated, and Microsoft does not currently advertise the expired Windows 7/8.1 upgrade offer as an available free upgrade.

Previously activated Windows 10 PC: A clean reinstall of the same edition usually costs nothing if the device’s digital licence is still valid.
PC with a valid Windows 7 or 8.1 licence but no Windows 10 history: Do not assume that the old free-upgrade route will work; current eligibility and activation are not guaranteed.
New or unlicensed PC: You need an appropriate Windows licence to activate Windows. Check the PC’s documentation and Microsoft’s current purchasing and licensing information.

Windows 10 support has ended

Even if Windows 10 is already activated, support is a separate issue. Microsoft ended free support for Windows 10 on October 14, 2025. The operating system can continue to run, but ordinary free security updates, feature updates, and technical support are no longer provided through standard support for Windows 10 Home and Pro.

This matters when deciding whether to install Windows 10 on a computer today. An activated copy is not necessarily a safe long-term choice for everyday internet use. Microsoft offers an Extended Security Updates (ESU) program for eligible consumer devices, subject to its terms and enrollment requirements; availability and conditions should be checked directly with Microsoft. ESU does not turn Windows 10 into a currently supported feature-release platform.

For a computer that meets the requirements, moving to a supported Windows release is usually the more practical option. Check compatibility before upgrading: hardware requirements, available drivers, application compatibility, and the PC maker’s support for the device can all affect the result.

Check activation and edition before reinstalling

Before wiping a computer, confirm whether Windows is activated and which edition is installed. In Windows 10, open Settings > Update & Security > Activation. The page reports activation status and may indicate that Windows is activated with a digital licence. Also note whether the edition is Home or Pro; a licence for one edition does not automatically activate the other.

For a reinstall, use Microsoft’s official Windows 10 download page and installation media rather than unofficial download sites. Select the same edition that the device is licensed for. If setup asks for a product key and the computer has a digital licence, choose the option to skip entering a key. Connect to the internet after installation and check the Activation page again.

Back up personal files and make sure you have any needed recovery information.
Check activation status and write down the Windows edition.
Create installation media using Microsoft’s official instructions.
Install the matching edition on the same licensed device.
Connect to the internet and verify activation in Settings.

Common activation problems

A reinstall may fail to activate if the wrong edition was installed, the device was substantially changed, the original licence was not genuine, or the activation servers cannot verify the entitlement. A product key from a different edition or a key intended for another device may not work. A used computer may also have a licence that was never transferred to its current owner.

Start by checking the edition and activation status, then run the Activation troubleshooter from the Activation settings page if it is available. Make sure the device is online and that you are using the same Microsoft account associated with the digital licence, if applicable. If those checks do not resolve the issue, consult Microsoft Support or the computer manufacturer and provide proof of purchase or licence details. Avoid unofficial activation tools: they can be unreliable and may expose the computer to unwanted software.

Windows 10 versus upgrading to Windows 11

Windows 11 is not a free Windows 10 upgrade for every PC simply because Windows 10 was once offered free. Eligible, activated Windows 10 devices that meet Windows 11’s hardware requirements can generally upgrade without buying another licence, subject to Microsoft’s current offer and compatibility rules. PCs that do not meet the requirements may need different hardware or another supported operating system.

Use Microsoft’s compatibility guidance or the PC manufacturer’s specifications to check the exact model. Do not rely only on a processor being fast enough: requirements such as supported hardware and security capabilities also matter. If the computer cannot run a supported Windows version, consider whether the manufacturer offers another supported operating system or whether replacing the device is the better long-term choice.
