Retail Key or OEM Key — Which Do You Need?
This is the most common point of confusion when buying a Windows 10 licence, and it decides whether your key still works after a hardware change.
| Difference | Retail (this listing) | OEM |
|---|---|---|
| Transfer to a new PC | Yes | No — tied to the first motherboard |
| Survives a motherboard swap | Yes, may need phone activation | No |
| Clean reinstall on same PC | Yes | Yes |
| Typical price | Higher | Lower |
| Best for | Anyone who may upgrade or rebuild their PC | A build that will not change |
If you expect to rebuild or replace your machine at some point, the retail key on this page is the one that follows you. If the licence will live and die with one fixed build, our Windows 10 Pro OEM key costs less.
Windows 10 Pro Features You Unlock
BitLocker Drive Encryption
Encrypts the whole drive so the data is unreadable if the laptop is lost or stolen. This is a Pro-only feature — Windows 10 Home does not include it.
Remote Desktop Host
Lets you connect into this PC from another machine. Home edition can only act as the client, never the host, which is why remote workers usually need Pro.
Hyper-V Virtualisation
Run virtual machines directly in Windows without third-party software — useful for testing software or running a legacy OS alongside Windows 10.
Domain Join and Group Policy
Connects the PC to a company domain or Azure Active Directory and allows IT administrators to enforce settings centrally through Group Policy.
Windows Update for Business
Gives you control over when feature updates install, rather than having them arrive when Microsoft decides.
Windows Hello and Windows Defender
Fingerprint and facial sign-in plus the built-in antivirus and firewall, with security updates delivered through Windows Update.
Important: Windows 10 Support Status
Microsoft ended mainstream support for Windows 10 on 14 October 2025. Windows 10 still installs, activates and runs normally, and your licence does not expire — but Microsoft no longer issues standard free security updates for it.
Buy this key if you are activating an existing Windows 10 machine, running older hardware that cannot meet the Windows 11 requirements, or need a specific legacy application that has not been certified for Windows 11.
If your PC meets the Windows 11 requirements, we would point you to Windows 11 Pro instead, which is still fully supported. We would rather tell you that before you buy than after.
System Requirements
| Processor | 1 GHz or faster compatible processor |
|---|---|
| Memory | 1 GB RAM for 32-bit, 2 GB for 64-bit |
| Storage | Up to 20 GB available disk space |
| Graphics | DirectX 9 with WDDM driver, 800 × 600 or higher |
| Connectivity | Internet access required for activation |
| Other | A Microsoft account is required for some features |

Frequently Asked Questions
Is this a genuine Microsoft licence key?
Yes. The key is sourced from authorised reseller channels and activates directly against Microsoft’s activation servers. After activation, Settings > Activation will confirm that Windows is activated.
Will this key still work now that Windows 10 support has ended?
Yes. Activation and your licence are unaffected by the end of support. What changed on 14 October 2025 is that Microsoft stopped issuing standard free security updates for Windows 10 — the operating system itself continues to install, activate and run.
Can I move this key to another computer?
Yes. This is a retail licence, so it can be removed from one PC and activated on another. You may need to use Microsoft’s phone activation option when moving it, and our support team can walk you through that.
How many PCs can I use this key on?
One PC at a time. It can be reinstalled on that machine as often as you need. For several machines, see our Windows 10 Pro MAK volume keys covering 10 to 500 PCs.
Can I upgrade from Windows 10 Home to Pro with this key?
Yes. Enter it under Settings > Update & Security > Activation > Change product key and Windows upgrades from Home to Pro in place, keeping your files and applications.
What happens if the key does not activate?
Contact support@softkeyworld.com with your order number. We will diagnose the error — most are edition mismatches rather than faulty keys — and issue a replacement key or a refund if we cannot resolve it.
Does the key expire?
No. It is a perpetual licence with no expiry date, no subscription and no renewal fee.
