CrowdStrike Holdings Inc’s chief executive officer said that the company has identified the update that crashed Windows systems around the globe and that “a fix has been deployed”.

“This is not a security incident or cyberattack,” CEO George Kurtz said in a statement posted on X on Friday. “The issue has been identified, isolated and a fix has been deployed.”

CrowdStrike had warned customers that its Falcon Sensor threat-monitoring product was causing Microsoft’s Windows operating system to crash. It coincided with disruptions of Microsoft’s Azure cloud services, and the resulting IT outage hobbled businesses across the globe.

On Friday, McDonald’s Corp, United Airlines Holdings Inc, and the LSE Group were among the major companies to disclose a variety of issues with communications to customer service. KLM said it was suspending most flights because of a global computer outage. They were among the more prominent global corporations to report issues with their operations.

CrowdStrike shares fell 16% in premarket trading before New York exchanges opened on Friday.
