Windows 10 Upgrade Activates By Clicking Red X Close Button In Prompt Message (bbc.co.uk)

In a move guaranteed to annoy many people, Microsoft has "jumped the shark" on encouraging users to upgrade to Windows 10.

 Microsoft has faced criticism for changing the pop-up box encouraging Windows users to upgrade to Windows 10. 

Clicking the red cross on the right hand corner of the pop-up box now activates the upgrade instead of closing the box.

 And this has caused confusion as typically clicking a red cross closes a pop-up notification. 
 
The upgrade could still be cancelled, when the scheduled time for it to begin appeared, Microsoft said The change occurred because the update is now labelled "recommended" and many people have their PCs configured to accept recommended updates for security reasons.

 This means dismissing the box does not dismiss the update.

Brad Chacos, senior editor at the PC World wrote about this incident over the weekend, and described it as a "nasty trick".

Update:

Days after angering many users with its so-called "nasty trick", Microsoft has reversed its crazy decision to infuriate users by upgrading them to Windows 10 automatically. 

Users were angry that clicking the cross to dismiss the box meant that they had agreed to the upgrade. Based on "customer feedback", Microsoft said it would add another notification that provided customers with "an additional opportunity for cancelling the upgrade".

 Microsoft told the BBC it had modified the pop-up as a result of criticism: 

"We've added another notification that confirms the time of the scheduled upgrade and provides the customer an additional opportunity for cancelling or rescheduling the upgrade.

 If the customer wishes to continue with their upgrade at the designated time, they can click 'OK' or close the notifications with no further action needed."
