I have uninstalled the default weather gadget by accident (right-click any gadget and press "uninstall").
Now I want to get it back (the 3rd party gadgets don't seem as attractive as the standard one), but I don't know how.
Unfortunately, this folder
C:\Users\<user_name>\AppData\Local\Microsoft\Windows Sidebar\Gadgets only contains the 3rd-party gadgets.
I was able to find it here (on another system)
C:\Program Files\Windows Sidebar\Gadgets\Weather.Gadget, so I copied them to the same directory on my machine, hoping it would do the trick.
It didn't, because the gadget doesn't show up in the list.
Can someone suggest a way to install the default weather gadget back?
