Hi, welcome to Apple Discussions.
The usual place for an iTunes Library to live on a Windows 7/Vista box is C:Users<User>MusiciTunes. Depending on whether you started out with iTunes 8 or iTunes 9 inside the iTunes folder will be a bunch of library files and a folder called *iTunes Music* or *iTunes Media*. If you want it to (and it's the default option) iTunes will keep everything inside this iTunes Media folder organised. Anything that you add to iTunes from outside that folder will either be added and left where it is or copied (making duplicates) into the iTunes Media folder depending on your choices in Preferences.
So... if you want to rebuild your library from scratch my suggestion is that you move everything inside the iTunes Media folder before adding it to iTunes. If you let iTunes *Keep the iTunes Media folder organised* then it will shuffle things around as it sees fit. Any real duplicates will end up with filenames ending in " 1.mp3" or " 1.m4a" etc. which you can search for using Windows file search.
The above is all well & good for music files that have tags, e.g. AAC & MP3 files. WAV files don't have tags so on import you can lose useful information and Podcasts may have volatile info. that is not stored in the tag. Ideally you'd leave the originals in place rather than removing and adding again. If you started out with iTunes 8 then I recommend you upgrade your library to iTunes Media Organisation (File > Library > Organise Library) before importing and also (with iTunes closed) rename *iTunes Music* as *iTunes Media*.
