^ The problem with the script is that it's only immediately available if you're on W10 or Server 2016. Earlier versions require some fiddling with (installing
WMF 5.1). If you have to do that, InSpectre is much smaller and easier to run.
If you're a sysadmin for a network though, SpeculationControl is probably better because you can make scripts to execute it remotely on a bunch of computers and pipe the output to a logfile.
