Due to an old and vulnerable version of OpenSSL (0.9.8e) compiled into the Cisco Compatible eXtensions (CCX) component (INTEL-SA-00188), Intel removed the CCX software from the Intel® PROSet/Wireless WiFi Software version 20.90 onwards for Microsoft Windows 7*, 8.1*, and Windows® 10.

Note When upgrading an earlier version of Intel® PROSet/Wireless Software to version 20.90 or later, CCX functionality will be removed automatically if it was installed previously.

CCX software is typically used in an enterprise environment deployed with a Cisco-based wireless infrastructure.

Today the CCX software isn't installed by default when installing the Intel® PROSet/Wireless WiFi Software downloaded from Intel’s website, but the CCX software may have been installed by your computer manufacturer.

If enterprise customers still require CCX functionality (specifically one of the EAP authentication methods that are installed as part of the CCX software), enterprise customers may consider the following available solution:
