Not getting any Pictures appear in my photo stream file

After updating to ios 7.06 in November I have never received any pictures on my PC (windows 7) taken by my iphone 4s.I have just today updated to 7.1 hoping this would help but it did not. I can find them on the iphone in photostream and camera roll with no problems but there they stay. If I share the photo manually I can receive it on my PC but this is laborious as I have to remember to do it each time. Everything else such as contacts emails diary etc is doing what it should and updates each other without a problem. I understand that I may have lost pictures taken prior to the update and that is not an issue. I am receiving nothing since.

I have tried the following;

• turning icloud off and on for pictures after applying each change
• resetting the phone
• Deleting all photostream pictures (after copying them off directly)
• Choosing a different file other than my photostream for them to download to.

If any one out there could help I will be eternally grateful. Thanks
