To successfully install the Panasonic KX-TES824 USB driver on a Windows 10 64-bit system, you generally need to use the Windows 7 64-bit drivers , as they are compatible with newer versions of Windows.
If you have the original installation CD or have downloaded the driver package (usually named something like KX-TE824_USB_Driver.zip ), you can attempt to install it, but you must bypass Windows' signature enforcement.
Click and browse to the folder you extracted in Step 1.
