I saved my excel *.xls ,but I need to go back before saving.
 

I changed a register in a cell , then I saved the file with equal name. Then
I realized that the register was wrong so I need to go back before saving
because I don't remember which was the register. Is there any way for doing
that? Thanks

Open the back up copy you made, or if you emailed the original to
someone, look for a copy in your Sent folder.
