wpa_supplicant has support for being used as a WPA/WPA2/IEEE 802.1X Supplicant on Windows. Last official build for Windows 98 was 0.4.11 (2008-12-03) and last official build for Windows 2000 and later was 0.7.3 (2010-09-07). This port aims to restore functionality of modern versions of wpa_supplicant on older versions of Windows such as Windows 98, Windows 2000, Windows XP SP1, etc.

⚠️ This port is designed for old versions of Windows and incompatible with Windows Vista and newer.

Currently, there are several different build configurations with different features.

Builds with WPAS_CTRL_IFACE=standalone:
