A third party component which used a kernel extension in Windows, but did not need a kernel extension on either the Mac (System Extension, which runs in user space) or the Linux (eBPF, much more resistant to crashes) versions.
Why would Cloudstrike need a kernel driver on Windows, and not their other platforms? Microsoft is responsible for that design and not moving past it at the pace alternative systems have.
Additionally, there are other things Microsoft could have done. For example - if your computer fails to boot 3 times in a row, with a third party driver, how about automatically disabling the driver? If the driver manufacturer doesn’t like that, tell them to suck it up and write a driver that doesn’t crash.
