Read this before buying: Windows 10 security updates end on 13 October 2026.

Mainstream support ended on 14 October 2025. The consumer Extended Security Updates programme runs until 13 October 2026 and cannot be extended further. After that date, newly discovered vulnerabilities stay unpatched permanently.

Also worth knowing: this key activates Windows 11 Pro as well. If your PC meets the Windows 11 requirements, you can install Windows 11 Pro with it instead — at no extra cost.

Windows 10 Professional — OEM licence key

A single-PC licence permanently tied to the first machine it activates on. Cheaper than Retail precisely because it cannot be moved. Delivered by email within minutes.

What you get

  • Your product key, delivered by email (usually within 1–5 minutes)
  • The official Microsoft ISO download link
  • A step-by-step activation guide
  • An invoice, sent automatically
  • Key replacement or full refund within 24 hours if activation fails

Is OEM the right choice for you?

Choose OEM if: the machine is a fixed desktop or workstation you plan to keep as it is. Office PC, home desktop, a build you are not going to change.

Choose Retail instead if: you upgrade hardware, swap motherboards, or expect to move the licence to a future PC. The price difference is small; the flexibility is not.

The distinction matters most when a motherboard fails. An OEM licence is bound to that board — replace it and the licence does not come back. This is a Microsoft rule, not a seller policy, so no reseller can work around it.

What Windows 10 Pro adds over Home

BitLocker drive encryption, Remote Desktop (host), Hyper-V, Group Policy Management, and Active Directory / Azure AD domain join.

System requirements

  • Processor: 1 GHz or faster
  • RAM: 2 GB (64-bit)
  • Storage: 20 GB free

Frequently Asked Questions

What is an OEM licence and how does it differ from Retail?

An OEM licence is permanently bound to the first PC it activates on and cannot be transferred to another computer. A Retail licence can be deactivated and moved to a new machine. OEM is cheaper for exactly this reason. If you are unsure which you need, ask yourself whether this PC is likely to be replaced or substantially rebuilt within the licence's useful life — if yes, choose Retail.

Can I use this key to install Windows 11 Pro instead?

Yes. A Windows 10 Pro key activates Windows 11 Pro. You can upgrade an existing installation through Windows Update or clean-install Windows 11 Pro and enter this key. The PC must meet the Windows 11 requirements: TPM 2.0, Secure Boot, a supported 64-bit CPU, 4 GB RAM and 64 GB storage. Note the licence remains OEM — it stays tied to this machine either way.

When does Windows 10 stop receiving security updates?

13 October 2026 for consumer machines under the Extended Security Updates programme. Mainstream support ended on 14 October 2025. Businesses can extend through the commercial ESU programme to October 2028 at most. After the applicable date Windows 10 keeps running, but stops receiving patches.

What happens if my PC breaks or I replace the motherboard?

The OEM licence cannot be reactivated on the new hardware. Replacing a hard drive, RAM or graphics card is fine — the licence is tied to the motherboard. If you anticipate a motherboard change, buy the Retail version instead.

Can I use this key to upgrade Windows 10 Home to Pro?

Yes. Go to Settings → Update & Security → Activation → Change product key and enter it. The edition upgrade happens in place and your files, applications and settings are preserved.

Does this include the Windows download?

You receive a link to the official Microsoft ISO alongside your key. You download Windows from Microsoft's own servers — we never distribute modified installation files.
