comment What happens to TCP connections when I remove the ethernet cable?
@Brad I don't make that assumption any longer. But it is an important addendum to this answer that connections can be killed at the leisure of the OS due to some detectable link failures. The simplistic OSI model is not fully implemented in practice.

comment What happens to TCP connections when I remove the ethernet cable?
I just plugged the cable and it did nothing indeed. It could have, though. The OS did detect that the cable was unplugged. The hardware tells that to the OS. Of course not every link interruption can be detected but some can. It depends on the OS what happens then. It is not possible to logically deduce what must happen. It's an implementation choice.

@MichaelKjörling good point. But that's what happens. I just disabled my NIC using the Window network center and watched all TCP connections instantly die using TcpView.

That's what the model says but I believe real OSes detect some failures and kill connections immediately. That's just a useful thing to do.

comment What do you do if you are being hacked by something coming from a supposedly legitimate IP address such as from Google?
If you properly secure the device this should not concern you. This actually is the answer to the question: What to do? Secure the device.

comment Should I disable swap file if I have lots of RAM or should I move it to a virtual RAM drive?
@DanW I have never heard about that. That would rquire the app to explicitly check whether the paging file is on and stop working if it is not. Few reasons an app would care about the paging file. Assuming, though, that such apps exist: set the file size to 1MB.

@DanW those users should have disabled the file and would have gotten even better results. Putting the paging file on a RAM disk is always inferior to having no paging file at all.

@begtodiffer it is true that Windows misjudges paging decisions all the time. But with out page file at all, instead of one on a RAM disk, there is nothing to misjudge.

As of today all download locations that I could find contain OpenCandy malware.

Having a paging file on a RAM disk never accomplishes anything. You take away a certain amount of available memory and add a certain amount of virtual memory. Null-sum. Just have no paging file.

comment How to limit HDD write speed for chosen programs
@Luaan yes, but a suspended app cannot issue more IO requests. The old ones complete, and then there is a pause. This was just an example to show that throttling IO is possible in principle. It's just not built-in to Windows, but many techniques for doing that exist. You can even extend Windows with a driver to do that.
