Makes sense, there wouldn’t be many 200-300 € laptops if Windows cost 80-100 € for them.

Yep, and not a small price at that. While the home license is not as expensive, it’s still mid two digits. IIRC pro version typically costs around 100 € even as the bundled OEM license, especially if you’re buying a laptop from a smaller manufacturer. That’s the amount I remember the price going down if you drop windows licensing from a corporate laptop lease.

In any way it’s not an insignificant price.
