Additionally, no matter what Windows ISO you run, use MAS and change your edition to Enterprise. You can configure a Windows Group Policy that sets telemetry even lower than normally possible (I used to think this set it to zero telemetry, but apparently that’s not the case). Windows will only honour this setting if you’re running an Enterprise build.
In the case of OP this comes with one small caveat however, which is that the Windows key they paid extra for is useless
Oh boy, does this also hold for people who don’t like any pets?
