Understanding Windows License During Upgrade to Windows 11

09 Sep 2025

When acquiring a new PC specifically designed for Windows 11, the necessity of purchasing a new license is oftentimes not required. This is largely owing to the ability to utilize your existing Windows 10 license, provided certain conditions are met. The transition from Windows 10 to 11 is often free, seamless, and hassle-free, given that your hardware satisfies the required criteria. During the upgrade process, Windows autonomously checks hardware compatibility, prompting the installation upon approval, thereby retaining your existing license.

Understanding the Digital License

The concept of a digital license is central to this upgrade process. Created initially when Windows 10 was installed, it comprises a hardware hash and a product key, stored securely on Microsoft's servers. It’s important to note that minor updates to your system (such as altering peripherals or RAM) do not disrupt this digital license. However, a motherboard change necessitates the re-entry of the product key post-installation. To verify activation status and ascertain if your license is associated with your Microsoft account, navigate to Settings -> System -> Activation.

Operating Without a Valid License

Windows allows installation and use for 30 days without a product key; nevertheless, this practice falls outside legal parameters without a valid license. After this period, a watermark is displayed, and customization options become inaccessible.

Upgrading with Component Changes

If your hardware doesn't meet the necessary requirements for Windows 11, options include using unsupported hardware installers like Rufus, upgrading key components (such as the motherboard or CPU), or purchasing a new PC with a pre-installed license. For instance, you can verify the TPM version needed with the utility tpm.msc.

Transferring Your License

Moving a Windows 10 license to a different computer necessitates ownership of a retail version—OEM licenses that accompany a computer cannot be transferred. You can determine the nature of your license via the command slmgr -dli as an administrator. Only 64-bit Windows 10 systems can migrate to Windows 11, and edition changes during the free upgrade aren’t allowed. It is crucial to back up vital data before proceeding with installation.

Purchasing Licenses

In the absence of a digital license or product key, purchasing is an option through the Settings menu or authorized retailers. Standard costs are $139 for Home editions and $199 for Pro. Be cautious when purchasing keys online as they may be invalid or blocked, whereas System Builder versions, while lacking direct Microsoft support, offer cost-effectiveness.

Locating and Linking the Product Key

Your product key can be located within the purchase email, on a physical label, or extracted from a previous installation through a keyfinding tool. Linking this digital license to your Microsoft account enhances retrieval efficiency during subsequent installations.

Reinstalling and Activating

During a reinstallation, it's possible to bypass the product key entry initially. Post-installation, navigate to Settings -> System -> Activation and input your existing Windows 10 product key to activate Windows 11. Keep in mind the one-computer-at-a-time licensing restriction.

Status of Activation

The activation status is presented within Settings -> System -> Activation, indicating whether the system is activated, whether linked with a digital license, and if tied to your Microsoft account, or not activated which might necessitate purchasing a new license. Such insights ensure that compliance and optimum system performance remain in focus throughout the upgrade journey.
