What is all the Crowdstrike fuss about?

Crowdstrike are a provider of cyber security products used by enterprises.  An update issued for their software has caused Windows machines to crash resulting in a blue screen, the so called blue screen of death (BSoD).  This seems to happen at the point that the Crowdstrike software loads.

At present the nature of the update is not known.

The fix is complicated by the need to get into the file system of a non booting machine.  The usual way to do this is to go into safe mode to stop the Crowdstrike software launching and then remove a specific file.  The file is located at:

%WINDIR%\System32\drivers\crowdstrike

Delete file called C-00000291.sys.

Microsoft have suggested that rebooting a machine up to 15 times can also result in a successful boot.

None of our clients use the Crowdstrike product.  It does not form part of our managed services.  Therefore none of our clients are impacted by the issue.

If you find that your machine is blue screening please do get in touch with our support team and we will help get you back up and running.
