Microsoft support: the real phone number

Microsoft never calls, texts or shows a warning telling you to ring them about a problem with your computer. If something sent you looking for this number, that message was the scam.

The real Microsoft

  • You contact them, always
  • Never phones about a virus on your PC
  • Never asks for your password
  • Never asks for a verification code
  • Never asks for gift cards or Bitcoin

THE SCAM

  • They contact you, urgently
  • "Your computer is infected"
  • A full-screen warning that won't close
  • "Install this so I can help"
  • "Pay with gift cards"

This is what the fake warning looks like

This is what the fake text looks like

  • A website cannot scan your computer
  • Microsoft does not put phone numbers in error messages
  • The rush is the trick
  • Close the tab. Don't click inside it.

Questions people ask

Is 1-800-642-7676 really Microsoft?

Yes. It's Microsoft's toll-free support number in the United States, listed on Microsoft's own contact page. But a caller showing this number may still be a scammer, because caller ID can be faked. Hang up and call it yourself.

Does Microsoft ever phone customers about a virus?

No. In Microsoft's words: "Microsoft doesn't send unsolicited email messages or make unsolicited phone calls to request personal or financial information, or to provide technical support to fix your computer." If someone calls you, hang up.

A full-screen warning says my PC is blocked. Is it real?

No. Microsoft says: "Error and warning messages from Microsoft never include a phone number." Close the browser. If it won't close, restart your computer.

Someone asked me to pay Microsoft with gift cards or Bitcoin.

That's a scam. Microsoft says it "will never ask that you pay for support in the form of cryptocurrency like Bitcoin, or gift cards."

Someone had remote access to my computer. What now?

Disconnect it from the internet. From a different device, call your bank and change your passwords. Then go to What to do now. You can report the scam to Microsoft at microsoft.com/reportascam.
