Add Google Search in your browser address bar

One can now easily Google search for any term using the browser's
address bar, and the search results will be displayed to you in
the Google's page.

The following small registry tweak can do this for you;

Go to following registry path
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\SearchUrl

sometimes the 'SearchUrl' key might not be present, in that case add
it as sub-key under 'Internet Explorer'.

Now in right pane for above key 'SeacrhUrl', change the default value to

http://www.google.com/search?q=%s

press F5 to refresh registry and then exit.
For this tweak to work you might need to close all the browsers and
open again.
