Some of you might have noticed that there is a problem with the weather gadget. It is common for users to configure , the language , location and keyboard layouts to their convenience in the options given during the installation of Vista. But here-in lies a problem which is related to the weather gadget.
If you have chosen to alter the default settings for the following - Location , Keyboard layout and language to anything else , then you will see that the weather gadget will say " service not available "
This is a bug which is to be fixed by MS I think . After installation you can go to control panel and in the regional settings , you can change the settings back to default . Then you can get the weather gadget to work for any location in the world. Hope this helps.
