Manufacturer Leaving WiFi Key on New PC?

Hey,

I am not sure if this is the right forum for this--apologize if not--but I'm not sure what to make of this question I was asked.

A friend just got a new computer this week from a company we've all heard of before. She has only had it for a couple of days. While trying to remember the password to a wifi hotspot she connected to, she entered netsh wlan show profile (or whatever the command is) to see the name of the hotspot so she could do a key=clear.

After running the command, she noticed there was a profile of the name of the company. After running key=clear, it revealed that profile had a 9 digit key.

Questions:

1) Is this a normal thing? I've never noticed it before on any of my devices.
2) Are there any other security concerns (hardware or otherwise) that should be audited as a result of this

3) What--if any--use would this information be to anyone

​

That's it. Thanks for reading, and looking onward to reading the comments
