• CrowdStrike Engineering has identified a content deployment related to this issue and reverted those changes.
• If hosts are still crashing and unable to stay online to receive the Channel File Changes, the following steps can be
  used to workaround this issue:

Workaround Steps for individual hosts:

Reboot the host to give it an opportunity to download the reverted channel file. If the host crashes again, then:

• Boot Windows into Safe Mode or the Windows Recovery Environment
• Navigate to the %WINDIR%\System32\drivers\CrowdStrike directory
• Locate the file matching “C-00000291*.sys”, and delete it.
• Boot the host normally.
  Note: Bitlocker-encrypted hosts may require a recovery key.

Workaround Steps for public cloud or similar environment including virtual:

Option 1:

• Detach the operating system disk volume from the impacted virtual server
• Create a snapshot or backup of the disk volume before proceeding further as a precaution against unintended
  changes
• Attach/mount the volume to to a new virtual server
• Navigate to the %WINDIR%\\System32\drivers\CrowdStrike directory
• Locate the file matching “C-00000291*.sys”, and delete it.
• Detach the volume from the new virtual server
• Reattach the fixed volume to the impacted virtual server.

Option 2:

Roll back to a snapshot before 0409 UTC.
