Will Imaging a win10 OS to a new disk, cause me to have problem with Microsoft key or license?

Imaging a Windows 10 OS to a new disk can potentially cause issues with the Microsoft key or license, depending on the type of media used to create the image. If the operating system image was created using retail or evaluation media, you will likely need to specify a product key during the installation process, as the installation may stop if a key is required and not provided.

However, if the image was created using Volume License media or certain OEM media, you might not need to specify a product key during the deployment, as these types of media can allow for bare metal deployment without requiring a key. It's essential to know the type of installation media used to create the operating system image to avoid any licensing issues during installation.

To ensure a smooth installation, it's recommended to test the deployment first by deploying only one node with that operating system image to confirm whether a product key is required or not.

However, if the image was created using Volume License media or certain OEM media, you might not need to specify a product key during the deployment, as these types of media can allow for bare metal deployment without requiring a key.

In the quote above you mention "certain OEM media". Can you specify what you mean there?

Hi, I'm Rodrigo and I will help you.
Certain OEM media means the media provided by the device manufacturer.
If your computer came with Windows installed, and it is from a PC brand (HP, Dell, Asus, Lenovo), not a custom build, it came with an OEM license, usually you don't need to enter a license when installing Windows on the new drive.
