I wonder if Microsoft will give a price break to the thousands (maybe millions) of users like me who bought the Win8 Pro Upgrade shortly after it was first available, but never installed it. I have two boxed retail Win8 Pro Upgrades sitting on the shelf unused and I'm still running Win7 Home Premium SP1 on both of my systems. IF the Win9 Upgrade can be bought for as little as $20., I'd probably take a chance on it.
It should be as simple as submitting the Win8 product key to MS to qualify for a reduced price Win9 Upgrade that will update Win7 directly to Win9 without having to install Win8 first. But then, that would be the smart way to market it. If I have to go through the hassle of installing Win8 before upgrading to Win9, they can forget it!
Microsoft has never been customer-friendly, preferring to use their market clout to bludgeon their customers into the "MS way of thinking", rather than considering what their customers really want and need.
