I recently got a laptop with Windows on it. I wanted to do a Powerpoint Presentation, but it wasn't on the device and if I wanted to download it, it cost something. Can't you get this for free on Windows devices?
No, unfortunately it is not free. You can either buy it once or purchase it as an annual subscription.
No, unfortunately not, but you can buy all 4 programs forever for 120 euro or so.
Libre Office, on the other hand (is very similar), is free.
Only if you belong to the right group is it free.
