No access to ports

Hello, I plugged an arduino UNO on my computer (windows 10) for the first time, 2 leds are switched on. I would like to use it but I have no access to the different ports. Someone told me to check my drivers but I have no unknown peripheral device on my computer, like if nothing was detected.

Can someone help me ?

Make sure the USB cable is fully inserted into the USB jack on the Uno and your computer. Especially with a new Arduino board, you might have to use a bit more pressure than normal to get the connector all the way in. An incompletely inserted USB connector can provide a power connection (and thus light the LEDs on the board), but not provide a data connection (and thus no port).

Try a different USB cable. You might have a damaged, defective, or charge-only cable that doesn't connect the data lines.
