I've tried this at least 3 times, once under on-line guidance of Microsoft Tech Support. Never worked either. What I REALLY need is for someone to give me step-by-step instructions of how to perform the reset in a way that will result in the fewest after reset problems that I can't anticpate, e.g. losing apps I can't recover, losing data files, Windows not running at all, the AU still not working, etc.
The USB method has not worked before. Is the link you are referring to the one that ends with "windows10startfresh"? If so, I already have info on this from the Windows Secrets website, which provides additional instructions. BTW, this method is referred to as the "Refresh Tool" and not a system reset. The latter uses OEM software from the Recovery drive, which would not work for me since my PC came with Windows 7 Home and I'm now on 10 Pro. Once I return from vacation in a few weeks, I'll try the Refresh Tool and see how it goes.
