If you have EC2 instances running Windows on AWS, here is a trick that works in many (not all) cases. It has recovered a few instances for us:

• Shut down the affected instance.
• Detach the boot volume.
• Move the boot volume to a working instance in the same region (us-east-1a or whatever).
• Remove the file(s) recommended by Crowdstrike
• Detach and move the volume back over to original instance
• Boot original instance

Alternatively, you can restore from a snapshot prior to when the bad update went out from Crowdstrike. But that is not always ideal.
