If the data on the drive is not yours, and you don't need it anyway, why not boot up the laptop with a Flash Drive with another OS on it, like Win-10 or 11, and just make it a clean install. That's what I'd do.
In fact, I did something very similar, just recently to an HP laptop that was given to me, out of an estate.
It's now running Windows 11/Pro/64 with NO trace of the previous owner, password, etc.
