I have been running Opera 40.0.
I upgraded from Windows 8 to Windows 10 about three months ago and everything worked fine.
Last night Windows 10 did an update and this morning I have lost all my Opera History, Contacts and Favourites.
Where can I look to find my Favourites.
All the "Favourites" files I can find on searching Windows Explorer are empty.
Windows 10 also won't let me log into Outlook from the start screen and repeatedly says I should close the application and log in again or I can continue witha temporary login that won't access my data and will not be retained on logout.
Feckin Microsoft !!
