We received the same phone call. Asked for that number to call back. Scammers for sure and not true. How would they now if we have errors or not??? Nothing is happening.
Nice try, but no you didn't, your a shill and a liar to boot! This is a scam!
The only persons who should be touching your computer is you, your manufacturer, Real Windows support that you have called and/or maybe a real live tech you see face to face!
