To activate Windows 10 Pro on a computer that originally came with Ubuntu and has an OEM Windows 10 Pro license, you can follow these steps:
- Install Windows 10 Pro: First, you need to install Windows 10 Pro on your computer. You can do this using a bootable USB drive or installation media.
- Use the OEM Product Key: During the installation process, when prompted for a product key, enter the OEM product key that is associated with your Windows 10 Pro license. This key is typically found on a sticker on the device or in the documentation that came with it.
- Activation: After installation, Windows should automatically activate if the product key is valid and matches the version of Windows you installed. If it does not activate automatically, you can go to Settings > Update & Security > Activation and select Activate to try activating it manually.
If you encounter any issues with activation, you may need to contact Microsoft support for assistance with OEM activation.
