The latest Kali Linux 2019.4 release includes a special theme to transform your Xfce desktop environment into a Windows look-a-like desktop. The theme has been designed for those who work in public places or office environments and don’t want people to spot that you’re working on Kali Linux, an operating system popular among hackers, penetration testers, and cybersecurity researchers. The team assured that starting with the 2020.1 version, which is due in the new year, a 16GB SD card will be the minimum supported one.
