Activate windows
Windows uses a system called Product Activation to ensure that it is only installed and used on one device at a time. Activation is closely tied to the hardware of the machine, including details like the motherboard, CPU, and other components. When you restore a system image to a different machine, Windows detects that the hardware has changed significantly. Those changes in hardware often trigger a reactivation requirement.
Boot into Windows
Activation
Click on the "Start" button. Then click on the gear icon labeled "Settings" to open the Settings app.
On the right, click on the "Activation" option. This will open the Activation page where you can view the activation status. Here it says: "Windows is activated with a digital license". This is because we have "internet access" so Windows could re-activate. Consult official Microsoft documentation for your situation.
