I would love to know, If you know some way to mitigate DDos/Dos attacks on Windows. In Linux we can Mitigate using the IPTables Almighty, but I wonder If there is something like that in Windows.
I am talking about pure Window Protection, No Cloud Based Protection like CloudFlare and Porxy like Nginx.
iptables is a firewall. It does not mitigate a DDoS attack, because by the time the traffic reaches your software firewall, it has already consumed your bandwidth and succeeded in its purpose.
Any firewall software on Windows (including the built-in one) is every bit as successful at mitigating DDoS attacks as iptables is on Linux.
The only real solution to a DDoS is to get the traffic dropped up stream, by your ISP or their upstream provider, assuming you don't already have a distributed, resilient infrastructure setup in place that's designed to withstand DDoS attacks, of course.
