It happens more often than you think. So you had your resident household tech guru set up your laptop to connect to your home Wi-Fi.
Your computer saves the Wi-Fi password and connects automatically when it's in range. So far, so good. Everything works as it should, every day, that is... until it doesn't.
It could be due to a variety of reasons: a software update, a bug or your laptop network settings may simply have been accidentally reset.
But whatever the cause may be, there WILL be times your default Wi-Fi network password will have to be reentered again.
Instead of bugging your tech guru every time for the password (and maybe he/she doesn't even want to share it with you anyway), wouldn't it be great if you have it saved somewhere, minimizing the humiliation of having to beg for it each time?
Enter NirSoft's free utility WirelessKeyView.
WirelessKeyView's website states that it "recovers all wireless network security keys/passwords (WEP/WPA) stored in your computer by the 'Wireless Zero Configuration' service of Windows XP or by the 'WLAN AutoConfig' service of Windows Vista, Windows 7, Windows 8, Windows 10, and Windows Server 2008."
This means if a Wi-Fi password was saved and configured on your Windows computer, WirelessKeyView will be able to retrieve it.
(Note that it will only work with saved Wi-Fi networks. It will not decipher nor crack passwords of networks you have not joined beforehand.)
You could then save all these keys as a text, html, or xml file to save on your computer or to print for safe keeping.
You can also copy a single key to the clipboard for pasting into another application. WirelessKeyView even allows the file export of these wireless keys and import them to another computer.

Important: As noted by NirSoft, WirelessKeyView may trigger certain anti-virus programs (such as Windows' own Windows Defender) and flag it as dangerous or infected with a Trojan/Virus. This is a false positive.
Using this application is as simple as extracting the contents of the .zip file and clicking on WirelessKeyView.
As promised, the program will then display all the Network Names, Keys and Key Types stored in your Windows computer.
