I am an IT professional and even I found this stupid and a bit tedious!! Ultimate solution: Uninstall Adobe READER (Edge works by default in Win10)!!
That is not a solution, it is a painful work around. For the record, this is not software based since the same things happens on PDF files and Image files - it is a microsoft issue that doesn't happen on my Windows 10 machine at home, but does on my Windows
7 at work.
What I can't understand is why Microsoft can have this error reported since 2011 and not have provided a fix. To my eyes, it seems when the preview handler 'previews' a file, it doesn't close it. I need to preview to work my way through images, so doing
what you suggest every time is a nightmare, and having to save as every time on a PDF is even more annoying.
