Meteorologist Metinka Slater was warning residents of a Thunderstorm on a live broadcast on Wednesday when Microsoft struck.
She handled it with humor. "Microsoft recommends upgrade to Windows 10, what should I do? Don't you love when that pops up?" Slater joked.
Someone backstage must have quickly dismissed Microsoft's recommendation because instead of an upgrade and reboot, the message disappeared and citizens of Iowa were able to get the rest of their weather report.
