Yes, the driver is used in case you can’t activate WiFi through the physical button. However, this provides functionality for both ways (physical and digital). For drivers, it’s indicated to download the driver for your architecture only (eg. 64bit). However, this doesn’t appear to be compatible with Windows 10. You’ll have to wait a little longer for HP to release the correct driver.
Always check HP Support for your product to see when the driver is released.
