That is the most likely explanation.
I've just upgraded to Win 10 from 7 on my Toshiba Satellite laptop. I do a lot of ebay, and pull pictures off of SD card to put into auctions. Sometimes a pic needs to be rotated, easy to do with the former photo viewer (I don't save these pics). NOW... anything I edit/rotate will show changed on the card memory, but if I pull from the card later when working on the auction, it seems to pull from the default image and isn't the same, edited pic. I checked the Windows 10 tips, and is the section "How To Get Windows Photo Viewer back in Windows 10" what I need??? Why is it doing this, is it saving my edited picture somewhere that I really don't care or know about??? Thanks.
