Microsoft Windows outage: Blue Screen of Death (BSOD)

Reports suggest the outage is linked to a recent update from CrowdStrike Falcon sensor, a cybersecurity software, causing Windows machines to experience "Blue Screen of Death" errors and restarts.

This is a critical system error that halts computer operation and displays a blue screen with error codes. BSODs are often caused by hardware or software failures from which the system cannot recover.

Impact of BSOD:

• Data Loss: If the BSOD occurs while unsaved work is open, data loss can occur.
• Productivity Loss: Frequent BSODs can significantly disrupt workflow and productivity.
• System Instability: The system might become unstable, experiencing random crashes and restarts.
