Changing extension on Windows 10
I recently had to reset my windows 10 due to malware. When I went to open my excel spreadsheets I was faced with a n "open with". I was unable to open with the selection provided so I went to the store and selected an xlsx extension. Now I find that it does not provide the power I use on excel and want to try to return to the original excel extension which is also xlsx. I am completely snowed as how to switch from one xlsx to excel xlsx. Can someone please tell me what to do.
