I've been using Vista Home Premium 32bit for a number of years. Last weekend I decided to try out Windows 7 as there are annoying features in Vista. I ran Vista in the morning all gadgets ok. I installed Windows 7 then sorted out my web connection and an hour later the weather gadget shows "Service not available."
I now know M$ have disabled this option because of security reasons but why they should they disable the weather gadget made by M$ if they should have provided an updated gadget? Also the currency gadget is disabled not that I use that one.
I found no useful solutions on Google all they said was check the region settings which are English (United Kingdom). I typed in London and New York but the service was still unavailable. But I did find Weather Vista Gadget 184.108.40.206
I downloaded it and scanned for virus and malware all clear, I added it to the Windows Sidebar folder opened the gadgets and added the new weather. The old weather is there with the same picture so I unistalled that one. The new one works exactly the same as the old one.
This works on Vista and Windows 7. That must have been bad timing for it to disappear from one OS to another.
