However, if the administrator is not there, the new computer has to access the encrypted wireless network, is it helpless? In fact, as long as there is a computer that has logged in to the encrypted wireless network and has the Windows 7 operating system installed, you can directly view the wireless network password, even if the administrator is not available, you can easily obtain the wireless network password.

The operation is also quite simple:

Turn on the computer connected to the wireless network and boot to the Windows 7 system. Click the network icon in the tray area at the bottom right corner of the desktop, select the wireless network connection to which you are currently connected from the shortcut menu, right-click and select "Properties". This will open the properties dialog box of the wireless network and switch to the "Security" tab. By default, the "Network Security Key" here will only display one small dot, which is naturally considered for security needs.
