I have reinstalled Windows 10 from scratch and now I have lost my bookmarks in the browser I most often used (Opera). I have only my old bookmarks from 2019 saved in my Opera account, but after that year I have used Opera without having synchronised bookmarks and without log in. But the computer is the same. I wonder if there is some way to recover my most recent bookmarkers. There are many. Maybe with Recuva? Another suggestion?
You could always give this a try depending on how long ago you did the new Windows install.
