I uploaded to Windows 10 some time ago but within a couple of weeks I decided to take the option to revert back to Windows 7, as basically I couldn't get on with the new software. Ever since this time I am unable to download any photos from my camera or mobile phone to my desktop. I have a dongle on my desk which is attached to a USB port and my PC won't acknowledge that it's there. Has anyone else experienced this and if so, what can I do to remedy it please? I don't have the original Windows 7 disks as my PC came ready loaded.
