Wanna bet? The only difference is that after July 29 Microsoft can ALSO charge you for the upgrade. If anything, that will make them MORE aggressive about it.
Since Microsoft argues that no one is being forced to upgrade, then any instance where the upgrade takes place MUST by definition have been approved (they say), and therefore the user will be charged (at some point, probably within a day or two) for the Activation code.
The upgrade downloads and installations will proceed exactly as they does now, or possibly more aggressively. I'd bet money on it (a donation to FR, of course!).
“therefore the user will be charged...”
That’s going to be difficult when they don’t have any method of payment for most Windows users (since the majority are purchased with OEM licenses from the hardware vendor).
If they do have a method of payment and charge you without specific authorization, then they just violated quite a few federal laws.
