I tried reinstall it with preserving applications and data. Installer did not preserved applications, but at least local users stayed local

If your user accounts remained then you did not reinstall Windows.
Perhaps you did a Repair install. Possibly a Reset.
A Repair install ought to have allowed you to keep your installed applications.

You are right, it was repair install. I wrote it very late at night.

Good you did that as there likely were other things affected you did not notice yet.

@swec, Even though it would be nice to find out what caused the problem, you have the computer working the way it should and that's what counts.

often you just never know what happened, except that something happened most likely in the software.
These are very complex machines.

It definitely ain't Windows 1.0 anymore.

Doubt all you like, but to really troubleshoot, you would want to Disable Eset just to find out.

Conclusion:
I did reinstall it. I really don't like this kind of solution. It seems to be unnatural for me. I just cannot get to used to solve problems by reboot and reinstall. But it did help.

I tried reinstall it with preserving applications and data. Installer did not preserved applications, but at least local users stayed local, only administrator was enabled for some reason, so i disabled it again.

Only important setting was pretty easy return back from my backup. So it took me only something between 60 - 90 minutes.

And CTRL+ALT+DEL is working again...

It must had be some setting which remained from original Windows Installer... only bad thing is, we don't know what it was.

Maybe someone else will solve it if this happens again.

I had the exact same problem.
Have you tried open "netplwiz" -> Advanced -> "Require users to press Ctrl+Alt+Delete" ?

When I used GPO to set this option, didn't work.
But enable manually fix the problem.
