At work, we have old computers and use Excel 2016. My computer is the only one where excel will randomly shut down. Now, there is an auto save that pops up to save a file. But I'll have 3-4 spreadsheets open and will see every autosave. Currently I'm forced to save each file, then open them again. Two questions?

1. Is there a faster way to recover these files?
2. Is there a way to find out what I need to prevent excel from randomly shutting down? This is the only computer this happens to.
