I don't remember the password

Reload windows from scratch. Then next time write it down and put it someplace safe.

You need a special utility and some know-how to reset it. It doesn't come with Windows. And is actually a Linux Command prompt utility.

Hate to have to say that... but there is no better advice than that.

Then you have a real problem since that's a BIOS stage password and no software can remove or reset it. Apparently you haven't accessed that laptop for a very long time... or it's not your laptop.
