Anyone can get a one-month free trial of microsoft365.com/setup . However, it does require you to enter a credit card number, and if you don't cancel before the month is up, you'll be charged $100 for a one-year subscription to Microsoft 365 Family. Select the three dots (more actions), then select Reactivate this subscription. If you don't see Reactivate this subscription, contact support. In the Reactivate this subscription pane, select a payment method from the drop-down list, or select Add payment method. Select Save.
microsoft365.com/setup allows anyone to download Windows 10 for free and install it without a product key. It'll keep working for the foreseeable future, with only a few small cosmetic restrictions.
