Hello, I made the mistake of upgrading from W8.1 to W10, within 24 hours I re-instated W8.1. However of course it is not that simple, now I cannot open a PDF or a Jpeg within the Outlook email app. I can right click and save but it does not question where I would like it saved and it seems to be saving in the photo app. Whilst I mention the photo app, I can no longer transfer a photo to my desktop account and of course it lost the one that was there before all the changes. Back with the email programme it is also now not possible to send a PDF file, strangely enough I can attach it and call it up from within the email but not send it. I have looked at the forums and check various settings but cannot find the one that might be blocking the feature, any ideas anyone?

Thanks

Brian
