Winter, er, the end of the Windows 10 free update is coming. And so will all the nagware and nag windows. Or at least promises Microsoft. However, that isn't stopping the company from trying one last time to force convince users to upgrade before time runs out (for Microsoft). Don't worry, it's not going to suddenly pop up a window in the middle of your weather forecast. Instead, it will fully block your entire screen with the reminder. Considering that same style is used for serious error messages, it has some shock effect to make users perhaps unwillingly click on that "Upgrade Now" button.
