I had just installed windows vista on my system and now I am facing a bit issue with the sidebar. It is not working at all. I tried to load it again but still the issue lies the same. I can't load widgets on the same. First when I restart my pc the task bar appear on the screen. But now it is not visible. I tried a command line tool also here but that too is not working. Can anyone help me here to find out a option by which I can simply activate task bar on the screen. I hope that will work.
