I am running Windows 10 with Office professional 2013. Excel does not seem to keep previously saved versions. In the File / Info tab is a section for Versions. It only lists the AutoSaved version. Previously (Excel 2003 running under XP) I had many many versions depending on how often I saved. It saved a copy each time I saved the file! now the is nothing usable (last autosave version doesn't help if I need to back out major changes that may have occurred a few hours before, but which I carefully clicked on Save to preserve that version. Can anyone help? Is it Office 2013 or is it a bug in Win 10?
