Problems with trying to make a macro keyboard on windows 10

Ive been looking at tutorials on how to use the keypad for the arduino. That isnt the problem though. The problem is that one tutorial on windows 7 says that you need to trick the computer to think that the arduino is a keyboard so it actually works. But im using Windows 10 and the only thing im able to do is connect to it and disconnect, does anybody know how to go into the properties of a arduino on Windows 10????

It sounds like you have several things confused here

A keypad is not the same as a keyboard. Using the right Arduino, such as a Leonardo, it is possible to write a program that sends one or many keystrokes to the currently active program in Windows. Those keystrokes could be triggered by entries on a keypad connected to the Arduino.

The effect is that pressing one key on the keypad could trigger a whole series of keystrokes to be sen. There is no need to alter Windows to do this. The PC is unaware of the source of the keystrokes and will act on them regardless of their source.

If you use an Arduino Leonardo or Arduino Micro then you can use the Keyboard library and no tricks are needed.
Before those existed you had to modify the firmware of the Arduino UNO or Arduino MEGA USB-to-Serial processor. I do not recommend that path.
Buy an Arduino Leonardo (or a clone of one) and use the Keyboard library to make your Arduino act as a USB Keyboard.
