Hello. I would like to create a LAN in my house between a desktop on Win 7 64 bits and a laptop on Win 7 64 bits. I would like to share files between these two PC, or eventually watch a movie or listen to music which are on my desktop with my laptop (and inverse). Do I really need a commercial software for that or can I use a free one ? Wich software do I need please ? Thank you.
