A content deployment released earlier today seems to have caused the problem.
Crowd Strike Engineering reverted those changes already & we have started to see systems recovering.
If you have a system stuck on a crash loop, currently, there is a workaround:
Boot Windows into Safe Mode or the Windows Recovery Environment
Navigate to the C:\Windows\System32\drivers\CrowdStrike directory
Locate the file matching “C-00000291*.sys”, and delete it.
Boot the host normally.
This is the latest Technical information at the moment, we’re on the incident tracking this to see if there is more to come over the next few hours
The bad content has been pulled to any online host. Hosts that can reboot should get automatically fixed.
It is worth setting the Throttling for updates to Unlimited.
The easiest way to do this, is to boot into safe mode, open a Command Prompt as an Administrator and enter the following commands:
del c:\windows\system32\drivers\crowdstrike\C-00000291*.sys
shutdown /r /t /0
