PXIe controllers that have been purchased with Windows 10 have a unique digital product key inserted into the BIOS of the system. Therefore, after installing Windows you need to connect your controller to the internet to activate your Windows automatically. Calling Microsoft to Activate using Key Management Service is not applicable for Windows that is provided by NI.
Windows 10 IoT handles activation differently from other Windows 10 editions. It cannot be activated without an internet connection. Until it connects to the internet, the system remains in a Deferred Activation state. This state functions the same as a fully activated system, with no limitations to user features or operation. The device remains in this state until it can reach Microsoft’s activation servers. If the product key is valid, activation completes automatically. If the key is invalid, only then does the system begin to restrict functionality.
