Office does save files every 10 minutes by default in a weird location. It doesn’t always work. But you can try it.
Open a file navigation window (not internet browser)
navigate to the folder
C:\Users\first.last\AppData\Roaming\Microsoft\Word
Where “first.last” is your username on this computer.
”Word” is the name of the program you were working on (Word, Powerpoint, etc)Look for a file starting with ~ OR “AutoRecovery”
For example“~WRA3759”
”AutoRecovery save of Document1”
Open this file and hope for the best.
