hat Is the Microsoft Windows 10 Pro Key?
The Microsoft Windows 10 Pro Key is a genuine product licence for one of the most widely used and trusted operating systems in the world. Designed for professionals, small businesses, and power users who need advanced security, remote access, and device management tools, Windows 10 Pro delivers a reliable, feature-rich computing experience on a vast range of hardware. Please note that Microsoft ended mainstream support for Windows 10 Pro on October 14, 2025, meaning the operating system no longer receives security updates or technical assistance from Microsoft. If your PC meets the requirements, we strongly recommend upgrading to Windows 11 Pro for continued security and support. If your hardware does not qualify for Windows 11, a Microsoft Windows 10 Pro Key remains a practical solution to activate and use your existing machine.

Important Notice — Windows 10 End of Support
Microsoft officially ended support for Windows 10 Pro on October 14, 2025. From this date, Windows 10 Pro no longer receives security updates, bug fixes, or technical support from Microsoft. Your PC will continue to function normally, but without ongoing security patches it becomes increasingly vulnerable to malware, viruses, and cyber threats over time. We recommend the following:
- If your PC meets the minimum hardware requirements, upgrade to Windows 11 Pro for continued security, support, and access to the latest features including Microsoft Copilot.
- If your PC does not meet Windows 11 requirements, consider enrolling in Microsoft’s Extended Security Updates (ESU) programme, which provides additional paid security updates for Windows 10 until October 2026.
- If you are running a mission-critical system that cannot be upgraded, a Microsoft Windows 10 Pro Key remains a valid and legitimate activation solution for your existing hardware.

Not Sure Which Windows Is Right for You?
If your PC supports it, upgrading to Windows 11 Pro is the best long-term investment for security, performance, and access to the latest Microsoft features. For organisations requiring the highest level of security and compliance, explore our Windows 11 Enterprise edition. Browse our full range of Windows 11 licences to find the right fit, or pair any Windows licence with a genuine Microsoft Office key for the complete Microsoft experience at the best UK price.
Is it still worth buying a Microsoft Windows 10 Pro Key in 2025?
It depends on your situation. If your PC hardware does not meet the requirements for Windows 11 — particularly TPM 2.0 — then a Microsoft Windows 10 Pro Key is a valid and cost-effective way to activate your machine. However, since Microsoft ended support on October 14, 2025, we strongly recommend upgrading to Windows 11 Pro if your hardware allows it, to ensure ongoing security and protection.
Will Windows 10 Pro still work after the end of support date?
Yes. Your PC will continue to function normally after October 14, 2025. However, Microsoft will no longer release security updates, bug fixes, or provide technical support. This means your device becomes increasingly vulnerable to new security threats over time. If you cannot upgrade to Windows 11, consider enrolling in Microsoft’s paid Extended Security Updates (ESU) programme for an additional year of protection until October 2026.
Is the Microsoft Windows 10 Pro Key I receive genuine?
Yes. Every Microsoft Windows 10 Pro Key sold at Digi Union is 100% genuine and Microsoft-authorised. Your key activates directly on Microsoft’s servers, confirming it as a fully legitimate licence.
How will I receive my Microsoft Windows 10 Pro Key?
Your key is delivered instantly to your email address upon confirmed payment. There is no physical shipping and no waiting — you can begin your installation or activation within minutes of completing your purchase, 24 hours a day, 7 days a week.
Can I upgrade from Windows 10 Pro to Windows 11 Pro using this key?
No. A Windows 10 Pro Key activates Windows 10 Pro only. To upgrade to Windows 11 Pro, you would need a separate Windows 11 Pro licence key. If your PC already runs a genuine Windows 10 Pro installation and meets the hardware requirements, the upgrade to Windows 11 Pro may be available for free via Windows Update.
What is the difference between Windows 10 Pro and Windows 10 Home?
Windows 10 Pro includes all features of Windows 10 Home plus a range of business-grade tools including BitLocker drive encryption, Remote Desktop hosting, Hyper-V virtualization, Windows Sandbox, Group Policy management, and domain or Azure Active Directory join capabilities. If you only need a basic home computing experience, Windows 10 Home is sufficient. For professional or business use, Windows 10 Pro is the right choice.
Is Microsoft Office included with the Microsoft Windows 10 Pro Key?
No. Microsoft Office is not included with Windows 10 Pro and must be purchased separately. Visit our Microsoft Office page to find the right Office edition at the best UK price, with instant digital delivery included.
