$1/year is entirely unreasonable. They build a product, they sell it to you, transaction ends there. They should sell you a product that works. Bug fixes are part of making the thing you bought closer to what was advertised, so it's part of the initial purchase. An OS is not a SaaS, and nobody considered doing it until it became popular, because it's a fad.

Of course a subscription would imply no upfront fee.

They're (presumably) double-dipping, the PC OEMs are already paying for the license.

In that case even $1/year would be unreasonable.

Says who, exactly?

Why should bug fixes be included?

If they should, for how long should they?

If your average user buys a new version every 5 years and the Pro version costs $250, they could charge $50/yr. $10/yr would be quite generous, unless they think they can get lots of people to stop pirating the OS. $10/month seems like an unlikely price point.

I honestly don't understand why anyone would pirate windows. Its full featured if you don't activate apart from a watermark. If you choose to activate you can get an oem key for like 10 usd.
