Windows 11 Pro vs Home vs Pro N: which key do I need?
| Feature | Windows 11 Pro (this key) | Windows 11 Home | Windows 11 Pro N |
|---|---|---|---|
| Best for | Work PCs, power users, anyone who wants BitLocker or Remote Desktop | Home PCs that only need the basics | Rare EU edition without Media Player and media codecs |
| BitLocker, Remote Desktop host, Hyper-V, Sandbox, Group Policy, domain and Entra ID join | Yes | No | Yes |
| Media Player, built-in codecs | Yes | Yes | No (installed separately) |

| Nerdused price, 1 PC | $29.99 | $29.99 | Not sold; see our Pro vs Pro N guide |
Pro and Home cost the same here for one PC and perform identically, so Pro is the sensible default unless you are certain you will never use its extra features. The full feature-by-feature comparison is in our Windows 11 Home vs Pro guide.
How activation works
- Pay, and the key arrives by email (check spam if it is not there within a few minutes).
- On a PC that already runs Windows 11: open Settings > System > Activation > Change product key, enter the 25-character key, and click Activate. On a Home PC this upgrades it to Pro in place, with one restart and no reinstall.
- On a new or blank PC: install Windows 11 from Microsoft's free media (our bootable USB guide covers it), enter the key when asked or skip and enter it in Settings afterwards.
- Settings then shows "Windows is activated with a digital license". Microsoft records the activation against your PC's hardware, so a later reinstall on the same PC activates automatically.
If activation fails, our Windows 11 activation guide walks through the error codes and phone activation, and live chat is open around the clock.
What kind of key is this?
It is a genuine Microsoft product key that activates online with Microsoft's servers, which is the only real test of a legitimate key. The license is for the PC it is activated on: you can reinstall Windows on that PC as often as you like, and the digital license returns. It is not a subscription, not a KMS or "volume activation" key that expires after 180 days, and not a shared account. Our OEM vs retail keys guide explains the difference between key types, and our cheap Windows 11 keys guide explains why a genuine key can cost this much less than the Microsoft Store.
System requirements
Windows 11 needs a 1 GHz or faster 64-bit processor with two or more cores on Microsoft's supported list, 4 GB of RAM, 64 GB of storage, UEFI firmware with Secure Boot, TPM 2.0, and a DirectX 12 graphics adapter. Microsoft's Windows 11 specifications page has the full list and the PC Health Check tool.

Yes. Every key activates directly with Microsoft. Nerdused is a UK company and a member of the Microsoft Partner Program (ID 6467441). If a key does not activate, we replace it or refund you in full within 30 days.
Can I use this key to upgrade Windows 11 Home to Pro?
Yes. Enter it under Settings > System > Activation > Change product key and Windows switches to Pro in place, keeping your files and programs. Step by step in our Home to Pro upgrade guide.
How many PCs does one Windows 11 Pro license cover?
The option you buy: 1, 3 or 5 PCs. A 3-PC key activates on three separate machines. Each PC keeps its own permanent activation.
Why is a Windows 11 Pro key cheaper here than on the Microsoft Store?
Microsoft's $199.99 is its retail list price for a license sold one at a time. Nerdused buys licenses in bulk, sells them with no box or packaging, delivers by email, and passes the saving on. The key is genuine or you get your money back within 30 days.
Do I need a Microsoft account?
Not to activate. The key activates the PC whether you sign in with a Microsoft account or use a work account through your organization.
Does Windows 11 Pro come with Office?
No. Office is separate; see Office Professional Plus 2024 or our Office 2024 editions guide.
