Microsoft and other legitimate tech companies do not send unsolicited email messages, make unsolicited phone calls to request for personal or financial information, or fix your computer. These tech companies will never proactively reach out to you to provide unsolicited PC or technical support. Any communication we have with you must be initiated by you. And, don’t call the number in the pop-up messages displayed on your computer or mobile device. Microsoft’s error and warning messages never include a phone number to call.
