Hi,

Thank you for sharing your question. I appreciate you explaining your need to upgrade 35 devices from Windows 11 Home OEM to Windows 11 Pro. I understand how important it is to secure the correct licenses in a straightforward and compliant way, especially when managing multiple devices for an organization.

Based on current Microsoft guidance, upgrading OEM devices to Windows 11 Pro requires purchasing separate Windows 11 Pro licenses—one for each device—because each installation of Windows Pro must have its own valid license. For quantities such as 35 units, Microsoft recommends obtaining these licenses through Microsoft Commercial Licensing or an authorized Microsoft reseller, as this provides proper volume purchasing and ensures compliance for all devices.

Once the licenses are acquired, each Windows 11 Home device can be upgraded to Windows 11 Pro by going to Settings → System → Activation → Change product key and entering the Pro license key assigned to that device. This completes the edition upgrade without requiring reinstallation.

If you prefer volume activation or need centralized activation and management, Microsoft’s Volume Licensing programs and tools such as Key Management Service (KMS) or Active Directory–based activation are also available options. These are typically used when managing larger numbers of devices under organizational licensing agreements.

May I ask whether your organization already works with a Microsoft licensing partner or if you would like assistance locating an authorized reseller in your region? If you share your region or preferred procurement method, I can guide you on the best next step to secure the licenses smoothly.

I hope this helps.

 

Best Regards,

Noel

For upgrading 35 OEM devices from Windows 11 Home to Windows 11 Pro, there are two main options shown in the context:

1. Purchase full Windows 11 Pro licenses (commercial/retail)
   • Windows 11 Pro is available as a full packaged product (retail) and preinstalled (OEM), and also via Commercial Licensing for organizations.
   • For 35 devices in a business scenario, use Microsoft Commercial Licensing or an authorized reseller to purchase Windows 11 Pro licenses in volume. The “Windows Commercial Licensing overview” describes Windows 11 Pro as available through Commercial Licensing.
   • Once licenses are obtained, each device can be upgraded from Home to Pro using the product key or digital license associated with that license.
2. Upgrade each device from Windows 11 Home to Pro via Settings / Microsoft Store
   On each PC that already has an activated Windows 11 Home OEM license:
   1. Go to Start > Settings > System > Activation.
   2. Confirm that Windows 11 Home is activated.
   3. If a Windows 11 Pro product key has been purchased for that device (from retail or your licensing program):
      • In System > Activation, select Change next to Change product key.
      • Enter the 25‑character Windows 11 Pro product key and select Next to start the upgrade.
   4. If a Pro key is not yet available for that device:
      • In System > Activation, expand Upgrade your edition of Windows and follow the prompts to purchase the Windows 11 Pro upgrade through the Microsoft Store app. This purchase provides a digital license tied to the Microsoft account used for the purchase.

Additional notes from the context:

• A separate Windows 11 Pro license is required for each instance of Windows 11 Pro, including each physical device or virtual machine.
• When Windows 11 Pro is bought through the Microsoft Store app, a digital license is issued and associated with the Microsoft account used for the purchase, instead of a traditional product key.

For 35 units, the most efficient path is typically to work with a Microsoft Commercial Licensing partner or authorized reseller to obtain Windows 11 Pro licenses in volume, then apply the Pro keys (or use the appropriate deployment method) on each OEM Windows 11 Home device via Settings > System > Activation.
