Anyone who hasn’t upgraded to Windows 10 will know how annoying the Microsoft popups that advise users to switch to its latest OS can be. Not only do they arrive quite frequently but often do so at the most inopportune moments.

On Wednesday morning, KCCI 8 News Meteorologist Metinka Slater discovered just how irritating this nagware really is, after a prompt appeared on her screen right in the middle of a live weather report.

As she was describing the conditions around Des Moines, Iowa, a recommended update alert that took up half the map suddenly appeared on her display. Trying to laugh off the incident, Slater said: "Microsoft recommends upgrade to Windows 10, what should I do? Don't you love when that pops up?"

The screen switched to another feed, but things didn’t get much better for Slater when her ‘clicker’ temporarily stopped working. “It’s that Windows 10, right? That’s what people are going to say. Don’t do it!” she joked.

Even though the incident was a minor one, it does highlight the often aggressive tactics Microsoft has used trying to achieve its goal of having Windows 10 running on 1 billion devices over the next two to three years.

In January, the Redmond company announced that future CPUs from Intel, AMD, and Qualcomm are only going to be compatible with its latest operating system. And in February, Windows 10 became a ‘Recommended update’ in the Windows Update application, rather than an optional one.

Whether KCCI 8 News will now switch to Windows 10 or just hope that the prompts don’t interrupt any more broadcasts is unknown.
