A faulty update from cybersecurity provider CrowdStrike is knocking affected PCs with Windows, forcing them into a BSOD (blue screen of death).
These are apparently the workaround steps. 
Discussion
From what I can gather this affects users running Windows Instances in the cloud (CrowdStrike appears to be the antivirus of choice for cloud providers)
Can end users actually boot into safe mode remotely? 🫣
Anyways, this is a great lesson of why one shouldn't run nodes in the cloud. I imagine there's someone out there with a windows-cloud setup panicking right now 🥹
Windows is a virus, format C: drive, install Linux.
