Guard against WannaCrypt ransomware

Applies to: Windows 10

A wide-spread ransomware attack, known as "WannaCrypt," targets out-of-date Windows devices. Given the severity of this threat, Microsoft recommends that you immediately update your Windows devices. 

  • Make sure you have automatic updates turned on, and your system is up to date. On Windows 10, Go to Settings > Update & security. You'll see your update status there.

  • For Windows 8.1, go to Settings  > Change PC Settings > Update and recovery. 

  • In Windows 7, go to Control Panel > Windows Update.

  • For more information about older versions of Windows, see Customer guidance for WannaCrypt and Microsoft Security Bulletin MS17-010.
