On Friday morning, thousands of Microsoft Windows computers experienced severe issues, resulting in the infamous Blue Screen of Death (BSOD). The glitch affected potentially millions of people worldwide, disrupting airlines, airport authorities, banks, government organizations, private companies, and municipal authorities.
Due to the scale and severity of the outage, many initially suspected a cyberattack. However, CrowdStrike CEO George Kurtz quickly clarified that the problem was due to a software bug, not a cyberattack.
George Kurtz explained on Twitter (now known as X) that the issue stemmed from a defect in a single content update for Windows hosts. He emphasized that Mac and Linux systems were not affected. Kurtz assured users that CrowdStrike was actively working to resolve the issue and that a fix had already been deployed.
CrowdStrike provided a temporary manual fix for affected users. They recommended booting Windows into Safe Mode or Windows Recovery Environment (WRE), navigating to C:\Windows\System32\drivers\CrowdStrike, locating and deleting a specific file (C-00000291*.sys), and then booting the system normally.
The glitch caused significant disruption across various sectors, including critical services like airports and banks. Many IT experts described the outage as one of the worst in history. Security researcher Troy Hunt highlighted the potential financial impact and compared the incident to the Y2K bug, noting that this time, the feared consequences had materialized.

CrowdStrike, a cybersecurity company trusted by numerous government agencies and large organizations, reassured its customers that they were addressing the issue through official channels. They encouraged affected users to stay updated via their support portal and website for continuous updates.
While the immediate crisis appears to be under control with a fix in place, the full impact of Friday’s Windows outage is still unfolding. CrowdStrike’s swift response and transparency have been crucial in mitigating the situation, but the event serves as a stark reminder of the vulnerabilities inherent in modern digital infrastructure.
