One of the most convenient features of Internet Explorer 7 is the possibility to redirect the phrase typed into the address bar to the default search engine (I prefer Google over Live! but it is quite easy to switch between different providers).
Suppose I type "c# pdf library" directly into the address bar. Instead of an error, Internet Explorer pops up the http://www.google.pl/search?hl=pl&q=c%23+pdf+library&lr= page and I can immediately browse search results.
I am used to this feature so much that yesterday I was quite surprised to see this instead of typical results page while searching for "Google Earth":
It seems that Internet Explorer first tries to match the phrase you enter into the address bar with names of some (which exactly?) local files, in this case the "Google Earth.lnk" located on my desktop.
Just a small inconvenience.
