That's the point, though. Linux will run on an old laptop that Windows will just die on.
If you have a friend other than the village idiot, you should be able to work it out, and save a bundle on software and a new laptop.
I've not signed up for a Microsoft Account (but I installed Win 10 myself, from scratch) - pretty sure you can just skip that bit, unless you want an Outlook.com email address. But you can use the email client for other email addresses, so it shouldn't be necessary.
