How do I retrieve an overwritten file in windows vista, I don't have the shadow feature.

You can try a free program such Recuva or PC Inspector, but if the file was over written it may be too badly corrupted to retrieve.
Thank you all: I did the soft ware route with no help. However, I'm using window vista, had I been using window vista ultra, there is an option built in to retrieve. Therefore, for your edification, when buying a new computer, said feature should be included. I'm going to try other software next like www.smartsheet.com and Recuva. Merry Christmas.
There is no such thing as recovery of overwritten files. Once a file is overwritten that means the original is gone because the new file occupies less/same/more space than the original.
Deleting a file simple marks the space as available which allows for recovery. Since it was not deleted there is nothing to recover.
Answers are only as good as the information you provide.
