Here’s what to know
Azure, Microsoft’s cloud computing platform, reported on Friday that it had discovered a problem affecting Virtual Machines running Windows Client and Windows Server with the CrowdStrike Falcon agent.

Azure confirmed that the problematic update has been withdrawn by CrowdStrike. The “Blue Screen of Death” is a Microsoft error screen.

He added that, at this stage, critical infrastructure and government services are not impacted. ABC News reported that banks and media outlets in Australia were also affected.
