If I was using my laptop d/stairs and I needed some info from my PC upstairs is there anyway of getting into my PC to do this? And if possible(without walking upstairs)how do you do it?? Thanks.
If you have a wireless router you can set up your upstairs computer to "share" its files, then by opening "network" on your laptop you should be able to "see" your upstairs machine and get to the files. Depending on your operating system you may need passwords on accounts.
