How to See the Wireless Keys that Windows has Stored
Note
The BBCODE in this needs a lot of fixing, but I wanted to submit it then work on it at a later date. The screenshots are also wrong for the x64 option - I'll fix those later
Warning
Some AVs are detecting this as malicious - this is because it's trying to access saved passwords. You may have to allow this file in your AV in order to use this.
When you join a protected wireless network, Windows will store the key to allow a connection to be automatically made next time you log on to the computer.
This information is stored in an encrypted format in the following locations:
XP: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WZCSVC\Parameters\Interfaces\[Interface Guid]
Vista: C:\ProgramData\Microsoft\Wlansvc\Profiles\Interfaces\[Interface Guid]
Windows 7: C:\ProgramData\Microsoft\Wlansvc\Profiles\Interfaces\[Interface Guid]
Because it's encrypted, we'll need a program to open it up for us
We will be using a tool from
Nirsoft called
WirelessKeyView.
