As a consultant I tend to jump around various networks and when working with other consultants it's not uncommon to need to share WiFi passwords for networks that you aren't currently connected to. The problem is, Windows 8 dropped the "Manage Wireless Networks" feature so this isn't as easy as it used to be but there is a simple way.

How to:
1. Open a command prompt
2. netsh wlan show profile name=[network name] key=clear

That's about it. Simple.

P.S. netsh is also useful for deleting profiles of the various public hotspots you've used. Why? Just ask Troy Hunt and his Pineapple :-)
