    Overview

    Microsoft scams exploit the dominance of Windows as the world's most-used operating system. Criminals impersonate Microsoft through fake tech support calls, phishing emails about Microsoft 365 subscriptions, and fraudulent Windows security pop-ups. These scams aim to gain remote access to your computer, steal your credentials, or charge for unnecessary services. Microsoft never makes unsolicited calls about computer problems.

    How This Scam Works

    1

    Cold calls from people claiming to be Microsoft support agents who have detected problems on your computer.

    2

    Pop-up alerts in your browser claiming Windows has detected critical errors, directing you to call a fake support number.

    3

    Phishing emails about Microsoft 365 subscription renewals or account security issues leading to credential-stealing websites.

    4

    Remote access scams where fake technicians ask you to install remote control software, then use it to steal data or install malware.

    Warning Signs

    Unsolicited calls from Microsoft or Windows support
    Pop-ups claiming your computer has critical errors with a phone number to call
    Emails about Microsoft subscriptions you do not have
    Requests to install remote access software like TeamViewer or AnyDesk
    Technicians who claim to find many problems after accessing your computer

    Real Scam Examples

    These are examples of messages used in this type of scam.

    Phone Call

    Hello, this is the Windows Technical Department. Our system has detected that your computer is sending error reports and may be infected with a dangerous virus. We need to connect to your computer remotely to diagnose and fix the problem before your data is compromised.

    Email

    Your Microsoft 365 subscription will expire today. Failure to renew will result in permanent loss of all emails, documents, and OneDrive files. Renew now for the discounted rate of $49.99: [Renew Subscription]

    How to Protect Yourself

    1Know that Microsoft does not make unsolicited calls

    Microsoft will never call you about computer problems. If someone calls claiming to be from Microsoft, it is a scam. Hang up immediately.

    2Close browser pop-ups without calling

    Use Task Manager (Ctrl+Alt+Delete) to force close your browser if a fake alert appears. Never call the phone number displayed in a pop-up.

    3Never give remote access to unsolicited callers

    Do not install remote access software at the request of someone who called you. Legitimate tech support only connects remotely when you initiate the contact.

    4Manage Microsoft subscriptions through your account

    Check your actual Microsoft subscriptions at account.microsoft.com. Do not rely on email notifications for subscription status.
