There's probably also very simple reason why this has happened... My current and only bet is that it's been triggered by the dated program that I ultimately decided to run on this day - had it installed since 2017 but never had opportunity to sort it out - that was continuously crashing despite applying various compatibility settings (Windows 7 and the likes); and I eventually decided to remove it and reinstall it from scratch - and it then worked. But then I spotted that Reliability Monitor contains the aforementioned crashes only. It's also interesting to know why Windows suddenly got stuck in this state and cannot be repaired by itself. But I don't think I will get an answer to this question. The fact that something allowed for this to happen does not add glory to Windows 10 itself as it reminds me form that respect of the other issue you guys helped me to resolve year ago or so. In either case I will continue to investigate - I do have backup image back from early June and can compare relevant files etc. And will keep you posted.
