Greedy patching: Hot patching is a way to quickly install security updates without requiring an OS reboot. Microsoft has offered the feature for years through its Azure cloud platform, but it's soon coming to non-cloud versions of Windows Server. It won't be free, but Microsoft's target audience is enterprise customers.
Forward-looking: Windows 7 will exit extended support very soon, but "micropatches" offered by 0patch are ready to take Microsoft's place in keeping the old operating systems safe and sound against Internet threats. At least for the most dangerous flaws discovered in modern Windows versions.
