While their PC can still connect to those wireless networks because the password was entered once before and are saved in the Wireless Configuration Manager in Windows, those passwords are hidden from plain view and cannot be extracted without the help of some external app. Many users around the world enter the WiFi password at their home or when visiting friends, works, or public spaces, and then forgot to remember it, write it down, or save it in a secure password manager. WiFi Password Decryptor is a security utility and password manager that can quickly and reliably recover lost or forgotten passwords for wireless networks on all modern versions of Microsoft Windows OS (starting with Windows Vista and newer).
