Recently a colleague asked me for the WLAN password I used for our guest network in one of our locations. It was a while ago I asked for it and then I saved it for reusing it.
Then I needed it again and thought: "Where is this stored and can I reveal it?"
Yes you can!
1. Simply open a Admin CMD.
2. Type in: netsh wlan show profile (This shows up all stored WLAN networks on your system!)
3. Type in: netsh wlan show profile "WLAN NAME" key=clear
The "Key Content" reveals the super secret password.
For security reasons this only works with and administrative command prompt.
Enjoy your new passwords ;-)
