This caller said he was calling from Microsoft and I hung up before he could say more. This individual had a foreign accent with call center sounds in the background.
I believe the blogs that say this is a male claiming to be from Microsoft and they need access to your computer. They call my number at least a few times per month. Obvious scammers. They change their phone number often. Never pick up your phone unless you know the caller personally. And report all scammers to the donotcall.gov site for what it's worth.
