What caused Microsoft Crowdstrike error outage? Reason explored

Microsoft Windows PCs have just begun recovering from a widespread Crowdstrike error that caused repeated Blue Screens of Death upon boot-up. The issue affected everything from banks to airlines, TV stations, and other service providers. Users reported their systems entered a boot loop following the error, further jeopardizing systems.

What exactly caused this widespread blockage? Turns out, Microsoft isn't to blame here. A faulty update pushed by Crowdstrike, a company the Windows maker has partnered with for security purposes, caused the mayhem. However, the exact cause of the issue is yet to be discovered, as pointed out by Professor Jill Slay of the University of South Australia in a conversation with CNN.

What are the possible causes for the Microsoft Crowdstrike error outage?

The Crowdstrike error is caused by a corrupted file in the system files. As mentioned earlier, the files originated from CrowdStrike. In fact, some tech enthusiasts booted their systems into Safe Mode and deleted the corrupted file. Their Windows machines booted up after that.

As per Microsoft's statement, the file could have crept into Windows while attempting a "configuration change in a portion of Azure backend workloads."

The issue has hit several companies including European low-cast aircraft carrier Ryanair, UK's Southern Rail, the Dutch airline KLM, US's Delta, United, and American Airlines, the Indian carrier Indigo, and more.

However, most systems have started recovering now with Microsoft Cloud and 365 apps already back online. While extra details on the error are still awaited, services and IT admins can now safely resume work to wrap up the week.
