I already previously had a Minecraft account and downloaded it on my laptop around 3 years ago. My laptop was old, bit it worked fine?

Until my computer died because it was old. I still have the account, and would it still cost $27 to download it again on my new windows 10 if I still have the account?

It shouldn't cost again. You have already paid for it. You should be able to install it on your new system.
