This question already has an answer here:
I had a problem with Steam a while ago and had to re-install it. When I re-installed I somehow set it to install on my desktop and it cluttered my desktop with all of the files. I moved all of files into one folder and started up Steam, and on starting up it created all of the files again on my desktop after I had just moved them into one folder. I know the default install is C:\Program Files\Steam but mine is set to my desktop, so is there anyway that I can change it back to there without having to re-install?
