Do you mean the Windows XP key?

I doubt Lucifer meant the Windows XP key. Hopefully, they will return and
answer.

In the meantime, I suspect, you were being asked if you have the Windows 7
Product key.
- it should be on a sticker on the machine or included with the material
received when the product was transferred to you.

One of the reasons why someone might ask 'if you can use a Windows 7 Product
key' is because Windows 10 can be clean installed and activated, when it has
a prior digital activated license, using the valid Windows 7 Product key for
that device.

Another reason for asking, also possible, is if 'you could use not knowing'
or 'if you knew' that you could use the Windows 7 Product key to activate
Windows 10.
