Occasionally I have some program that locks up in such a way that I cannot get other open programs to respond. Although I could just restart my machine, I often have ten or more documents, spreadsheets, etc., open that I am actively working on. Is there a Windows (10 in my case) command to save and close all open user applications? Or just to save all? Shut down is supposed to ask and then save if you say yes, but I have found it to be unreliable in this regard, especially with respect to programs that have not previously been saved.
Alternatively, is there a utility that will periodically autosave open files produced in programs I select, those that do not themselves have an autosave function?
