Wi-Fi

WPA (Wi-Fi Protected access

WPA is a security certification program designed by the Wi-Fi Alliance in response to weaknesses found in the previous system WEP (Wired Equivalent Privacy).
There are three WPA stamdards(?): WPA, WPA2 and WPA3.
WPA-PSK (PSK = pre-shared key) is designed for home, small office and basic uses.
In contrast, WPA-Enterprise (a.k.a. WPA-802.1X or just WPA) is designed for enterprise networks and requires a RADIUS server)
WPA is sometimes also referred to as TKIP standard.

Windows

In Windows, the currently used WIFI profile seems to be stored under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\Settings\Network\Preferences, value SelectedWiFiProfile.
