The terms ‘window openers’ and ‘window actuators’ are often used interchangeably but they are technically two different things. The term actuator means ‘component responsible for moving or controlling a mechanism or system’ and basically enables the window to be opened using motor driven automation.

Electric window openers usually refer to the device that is controlled by the actuators to automatically open or close the windows using remotes, sensors, or switches.

Using either terminology is fine as they are essentially the same thing just by a different name.
