Windows 11 Product Key — Genuine Keys, Instant Delivery
A genuine Windows 11 product key activates a full, permanent copy of Microsoft's latest operating system — no subscriptions, no nag screens, and no grey-market risk. At Nerdused every key is a genuine Microsoft licence, delivered to your inbox in about 60 seconds, activated online, and covered by a 30-day money-back guarantee. Windows 11 Home is $29.99 and Windows 11 Pro is $29.99 — against the $139–$199 Microsoft charges at retail.
Which Windows 11 key do you need?
Windows 11 Home ($29.99) is right for almost every personal laptop or desktop: it includes the full Windows 11 experience — the redesigned Start menu, Snap Layouts, DirectX 12 Ultimate gaming, Microsoft Copilot, and every security update.
Windows 11 Pro ($29.99) adds the business-grade tools: BitLocker drive encryption, Remote Desktop hosting, Hyper-V virtual machines, Group Policy, and support for up to 2 TB of RAM.
If you're unsure, our rule of thumb: buy Home unless you specifically know you need BitLocker or Remote Desktop — and if you're upgrading from Windows 10 Pro, stay on Pro so your licence type matches.

How activation works (3 steps)
- Order your key — it arrives by email in about 60 seconds along with step-by-step instructions.
- Enter it in Settings → System → Activation → Change product key (or during a fresh Windows 11 installation when prompted).
- Windows verifies the key online with Microsoft's servers and activates permanently. The licence is tied to your hardware and reactivates automatically if you reinstall.
If anything doesn't work, our support team fixes it or refunds you: that's the 30-day guarantee, and why we hold a 4.9★ Trustpilot rating.
OEM vs Retail keys — what you're actually buying
Most cheap Windows keys online are OEM licences: legal, genuine Microsoft keys originally intended to be sold with hardware. They activate exactly like retail keys and receive identical updates; the practical difference is that an OEM licence stays with the first PC it's activated on, while a retail licence can be moved to a new PC later. We label every product clearly so you know which you're getting — and unlike marketplace sites where anonymous third-party sellers list keys of unknown origin, we source ours directly through authorised distribution, which is why we can offer a real guarantee.
Why are Nerdused keys so much cheaper than Microsoft's?
Volume licensing and regional distribution. Software has no manufacturing cost — Microsoft sells licences to large distributors at a fraction of the retail sticker, and unsold volume ends up with resellers like us. It's the same key, the same activation servers, the same updates. What you're skipping is the retail markup. This is a legal and established market: we're an authorised Microsoft partner, we've completed over 800,000 activations, and every order is backed by a receipt and guarantee.
