Users of Microsoft Windows across the world are currently experiencing the "Blue Screen of Death" (BSOD) error, which is causing their systems to suddenly shut down or restart.
The users were unable to access various Microsoft 365 apps and services due to an error caused by a recent update at global cybersecurity firm CrowdStrike.
The Microsoft outage began early this morning today and has reportedly affected several companies, airlines, banks, and government offices across India, the US, and Australia.
Pictures posted on social media showed users' screens stuck on the recovery page displaying the following message: "It looks like Windows didn't load correctly. If you'd like to restart and try again, choose Restart my PC below."
"We remain committed in treating this event with the highest priority and urgency while we continue to address the lingering impact for the Microsoft 365 apps that are in a degraded state," the company said.
"Our services are still seeing continuous improvements while we continue to take mitigation actions," it added.

Blue Screen errors, also sometimes called black screen errors or STOP code errors, can occur if a serious problem causes Windows to shut down or restart unexpectedly.
What Caused Microsoft Windows Error
Microsoft said the preliminary root cause was a "configuration change" in a portion of its Azure backend workloads.
It caused interruption between storage and compute resources which resulted in connectivity failures that affected downstream Microsoft 365 services dependent on these connections, the US-based company said.
