I am not sure what "all the suggested maintenance" might entail.
Have you, for example, used the disk cleanup utility in Windows? Especially the "more options" panel?
Have you checked for zip files still remaining on your hard drive, even though you have unzipped them previously?
Have you reviewed the space you are allocating to System Restore?
Have you removed programs you don't use?
Have you already stored documents, pictures, and media to disk, but not deleted them from your HD?
