The replay came back:
You're likely to be doing some sort of scheduled activity, some kind of upgrade, updating, some kind of scanning, defragment or anything else. Find timed activities.
You can use Windows own Task Scheduler (make link %windir%\system32\taskschd.msc /s ) or open from Windows Administrative Tools folder
(%ProgramData%\Microsoft\Windows\Start Menu\Programs\Administrative Tools) or use some 3 part task manager.
To which I have responded:
That does not look like it. I am running 3 separate programs (one is a webinar) which I have run for the last 5 months. Two are trading platforms and are linked to international FOREX clocks as well as linked together. The third, the webinar, is linked to the my host company. It appears that one of the trading platforms may be the problem as that one does not come back online when the other two do. There is no upgrading or scanning or defragmenting going on. The whole system runs live so I guess it is constantly updating. The only link to windows 10 is that none of the trading platforms will run on any other system. The strange thing is it runs perfectly after the crash if I reload the programs. It has crashed 5 work days in a row now - although the crash is progressing forward in time by about half a minute per day.
