There is no subscription and no renewal, and every key activates online with Microsoft. You can reinstall Windows on that same PC as often as you need and it will activate again. Our 30-day refund promise applies to every order: a full refund within 30 days if your key has not been used or will not activate.
Most people buying Windows 11 want Windows 11 Pro. It adds BitLocker drive encryption, Remote Desktop hosting, Hyper-V virtual machines, Windows Sandbox, the Group Policy Editor and domain or Microsoft Entra ID join, and it supports up to 2 TB of RAM against 128 GB on Home. Windows 11 Home covers everything a family PC or a gaming rig needs at the same price. Both editions need a compatible 64-bit processor with two or more cores, 4 GB of RAM, 64 GB of storage, UEFI with Secure Boot and TPM 2.0. If your PC cannot meet those requirements, or you simply prefer the older desktop, Windows 10 Pro and Windows 10 Home are still available; note that Windows 10 stopped receiving free security updates on 14 October 2025, and the Windows 10 Pro key also activates Windows 11 Pro on a compatible PC.
