Why did they add the 'Network Share Key' thing to the OS? When I installed Win7 Home Premium on a friends comp, I copied the share key it gave me to the clipboard but before I remembered to create a text file to paste it in I re-started the computer due to some update it had installed, how do I get that key back? Thusfar I can't share anything on the network from the comp (this is a file share & shared printer comp for their laptop). Or better yet how can I configure Win7 to allow them to share additional folders without needing that key?
