WINDOWS problem

i was playing around with file extensions of windows and i actually ended up dunno how puting the default command for folders to be SEARCH..this mean when i double click a folder instead he open it he will just do SEARCH command under that folder...well...i worked around and created a command that uses internet explorer to open folders...it worked...but the problem is that as it is internet explorer it doesnt suport the "open in same window" what makes me get REALLY MAD because i dont like having to open 300 windows ... any help? any1 knows the command to open a folder thru the windows?
