Weird, it just installed on my Insider W10 (Build 18290). Will bookmark that though, thanks for the info.It's probably because it has not been updated for a while and it's digital signature is not co-signed by Microsoft.

Windows Firewall Control
KSC Personal/Family has a firewall, yes. The free version does not (unless they still haven't fixed that bug that allowed FW use in the Free).Bad news. I tried ZAF w/KSCF2019, and on boot, ZA stops KSC from loading just hangs. ZA Tech chat told me conflict. Maybe KSC also has a firewall? Does it? I just see Network protection module.
I removed ZAF, KSC loads fine. Moral, stick with WF, or try CF again.
The expiration date of that software seems like it may be coming soon, it's about to be folded into Malwarebytes. Thanks though.
