Did you have someone else set up the wireless network in your house, and can’t for the life of you remember the password? If so read on to see how you may still be able to recover it.
This should work for Windows 7, Windows 8, and Windows 10.
Note: Unfortunately this trick will only work if you are a local administrator on your machine, if you are not you will be prompted by UAC for administrative credentials.
Viewing Your Wireless Password From an Already Connected Machine
To view your wireless network password we need to get to the settings for your network adapter, so press the Win + R keyboard combination and type ncpa.cpl in the run box, then hit the enter key.
You will now see all the network adapters in your machine, right-click on the wireless one and select Status from the context menu.
When the Wi-Fi Status dialog loads up, click on the Wireless Properties button.
Then you will need to switch over to the Security tab.
Finally, check the Show characters checkbox to reveal your password.
That’s all there is to it.
Update: If this method didn’t work for you, try viewing a list of all your saved Wi-Fi passwords.
