How to recover lost documents?

When I updated to the latest edition I lost ALL my documents! I use Win 10. Never had lost any previously. How do I recover them?

Take a deep breath. Everything’s going to be ok.
Click Start, mouse over to Search, and then click ‘For Files or Folders’.
In the Search Results dialog box, type ‘ppt*.tmp’ under Search for files or folder named, and then click Search Now.
You’re looking for a file named something like ppt####.tmp.
Select the file you’re looking to recover and rename with a .ppt extension.
Move the file to the desktop, or another handy location.
Reopen, and pick up where you left off.
Another alternative method for Windows users is to use the built-in Office 2010 recover functionality:
Open PowerPoint and go to File > Information > Manage versions > Recover Unsaved Documents.
