A decade old PC didn't come with Windows 7, which shipped 17 years ago. It would have windows 10, which shipped 11 years ago, or conceivably 8.1 but I would doubt it. 4gb ram is also too small for that era.
I'm guessing this is the laptop they are talking about:

Windows 11, meanwhile, is more bloated than ever.
