Closing the upgrade prompt is the same as saying yes
I mentioned this in one of my columns for the local paper a few weeks ago, after a client dismissed the upgrade prompt and found her laptop automatically upgrading to Windows 10.
It is despicable behaviour by Microsoft and shows a certain amount of contempt and a lack of respect towards their customers.

Sneak Attack by Microsoft Initiates Windows 10 Upgrades When People Believe They Are Canceling
Microsoft appears to be playing a dirty trick to upgrade your computer to Windows 10 when you might believe you are rejecting the upgrade. If you simply close the window with the prompt to upgrade by clicking on the red X, they treat that as accepting the upgrade rather than rejecting or at least deferring it. There is no warning this will happen in the window you are closing. The only indication is in a separate support document.
There is no question that presuming approval is sleazy, but it goes beyond that. Microsoft’s behavior here contradicts Microsoft’s documentation for developers, which says: “The Close button on the title bar should have the same effect as the Cancel or Close button within the dialog box. Never give it the same effect as OK.” The same documentation also says “Use Cancel or Close for negative commit buttons instead of specific responses to the main instruction.”
Elsewhere, Microsoft has advised users specifically to “”Never click ‘Agree’ or ‘OK’ to close a window that you suspect might be spyware. Instead, click the red ‘x’ in the corner of the window or press Alt + F4 on your keyboard to close a window.”
It seems from the above that Microsoft’s rules don’t apply to Microsoft — especially when they want to grow their Windows 10 numbers.
