“Drivers are tested extensively through a process that involves many companies.”

That didn’t happen. Apparently, the policy for drivers does not apply to kernel modules… WTF!!

the driver in question was tested and passed WHQL. CrowdStrike included functionality in the driver to interpret a downloadable file (similar to an antivirus signature file). The file in the problematic update was malformed, and the CrowdStrike driver did not handle this case properly; Windows was unable to continue given the exception in question[1].

No operating system can guarantee that a driver will never cause the machine to crash. This wasn’t Microsoft’s fault.
