Licensing Process

Elbacom initiates the digital Embedded OEM Customer License Agreement (OEM
CLA) which enables the OEM to buy licenses and retrieve OEM Pre-Installation Kits (OPKs).
Elbacom provides Additional Licensing Provisions (ALPs) for the chosen embedded product.

Embedded OEM Customer (OEM) fill out the CLA online. Elbacom and Microsoft check the data and approve the CLA.
The OEM will receive the digital CLA contract. After the OEM signs it, Microsoft will counter sign it.
The customer can now order licenses and OPKs.

Elbacom provides Embedded OEM Customer (OEM) licenses, OPKs, toolkits.
