Windows 3.1 not being updated by Microsoft has nothing to do with Crowdstrike rolling out an update to their Falcon Sensor software including a file with 42kB of zeroes.
On Windows 3.1 you probably can’t run Falcon Sensor, so in that way it could be related. But it seems way more likely that Southwest Airlines simply didn’t use Falcon Sensor on their normal Windows 10 or whatever clients.
There are probably competitors to Crowdstrike, at least some companies would be customers to one of them.
The inverters are built with an automatic shut off during grid outages, specifically for lineman safety.
