add existing microsoft account to second pc

[pow2]

I'm setting up my new HP 17-by3063st 17.3" Notebook, Intel i3, 8GB Memory,
128GB SSD + 1TB Hard Drive, Windows 10. I'm prompted to set up a microsoft account. But when I enter my existing microsoft account email, I get message that this account already exists--without option to use the same account on my HP. Thank you.
