Hi,
You can purchase a Windows 10 Pro upgrade from Windows 7 Pro through several options:
Microsoft Official Store – While Microsoft primarily promotes Windows 11 now, you may still find Windows 10 licenses available through their official store.
Authorized Resellers – Retailers like CDW, Provantage, or Amazon may offer Windows 10 Pro upgrade licenses. Be sure to choose a full retail license or a volume license if you're upgrading multiple devices.
Microsoft Volume Licensing – For organizations, you can purchase upgrade licenses through the Open Value or Select Plus programs, which may require a minimum quantity.
Please note: The free upgrade from Windows 7 to Windows 10 is no longer officially available. You’ll need a valid product key to activate Windows 10 after installation. If you're upgrading a business environment, using volume licensing ensures compliance and imaging rights.
Quinnie Quoc.
