Question : Problem: I need to find inexpensive/free software that will allow me to control my home PC

My wife does medical transcription from home and is not very computer-literate.  My office is 30 minutes away so if I could just control her PC remotely it would save time and money.  I can't justify paying very much because I would only use it infrequently.
