Windows 10 Key: Genuine Licenses for PCs That Stay on Windows 10

Buy a Windows 10 key for a PC that stays on Windows 10

Your PC is not compatible with Windows 11, or you depend on software and drivers validated only on Windows 10? A genuine Windows 10 key brings the machine back to an activated, fully working system. Choose Windows 10 Home for personal use, Windows 10 Pro for work, or Windows 10 Enterprise LTSC 2021 for dedicated machines. Your key is delivered by email within minutes and activates on Microsoft’s official servers.

Good to know before you buy

• Windows 10 version 22H2 is the final release and the one to install.
• One key activates one PC, in either the 32-bit or the 64-bit version.
• The installation media can be downloaded free of charge from Microsoft’s website.
• A defective key is replaced free of charge for the lifetime of the license.

Windows 10 editions compared

All editions share the same interface and run the same software. The differences lie in business features and in how long Microsoft keeps shipping security fixes.

For most people, the choice is between Home and Pro. Pro is only worth it if you need disk encryption, remote access to this PC, virtual machines or a company network; for everything else, Home does the job. Our guide Windows 10 Home vs Pro vs Enterprise details every difference.

Every edition activates on Microsoft’s servers in the same way; only the features differ. One license covers one PC: for several computers, order one key per machine, or choose a multi-PC option where the product page offers one.

Windows 10 end of support: what it means for you

Microsoft ended standard support for Windows 10 on 14 October 2025. Your system keeps working, and security updates remain available through the Extended Security Updates (ESU) program:

• Personal devices: the consumer ESU program now runs until 12 October 2027 for Windows 10 version 22H2 Home and Pro. In the European Economic Area, enrollment is free with a Microsoft account.
• Organizations: paid ESU can be renewed year by year, up to October 2028.
• Enterprise LTSC 2021: it follows its own lifecycle, with security updates until 12 January 2027.

Windows 10 therefore remains a sensible choice for a computer that cannot run Windows 11, provided you plan the move when the hardware is replaced. Our article Windows 10 end of support: your options compares every solution, and if your PC is compatible, our Windows 11 key page explains how to switch.

How to install and activate Windows 10

1. Order your license and pay securely by card, Apple Pay, Google Pay or Bancontact.
2. Receive your key by email within minutes (48 business hours at most), with the activation instructions and a VAT invoice.
3. For a clean install, download Windows 10 version 22H2 from Microsoft’s website, create a USB stick and install the edition that matches your key.
4. Activate in Settings, Update & Security, Activation, then Change product key.

Before a clean install, back up your files: the process erases the system drive. And if the PC becomes compatible with Windows 11 later, for example once TPM 2.0 is enabled in the BIOS, your Windows 10 Home or Pro license carries over to the same edition of Windows 11 through Microsoft’s free upgrade.

Once activated, the license stays with your PC: after a reinstall on the same machine, Windows 10 reactivates automatically when it goes online. If a key does not activate, write to our support team with your order number: we reply by email 7 days a week within 2 hours on average.

Why a genuine Windows 10 key costs less

These keys are genuine licenses resold on the European second-hand software market. In its UsedSoft judgment (case C-128/11), the Court of Justice of the European Union ruled that a perpetual software license sold in the EU can be resold, provided the original owner no longer uses it. You therefore pay a second-hand market price, not the price of a new boxed copy.

What you install does not change: Windows 10 activated by Microsoft’s servers, without any third-party tool or “activator”. Be wary, on the other hand, of free “generic keys” shared on forums: they can start an installation, but they never activate Windows.
