Additionally, that it’s younger and more powerful sibling, Windows Defender, comes pre-installed on all Windows machines 8 & 10.

However the structure on which this was built was very appealing, showing the OS flavours, company history, and idle and working set. Maybe include a breakdown of CPU compared to RAM usage too?
