What it does
HardeningKitty is a PowerShell-based Windows assessment and hardening tool that checks configuration against predefined finding lists.
HardeningKitty reads settings from the registry and other configuration sources, then assesses them using a findings list. It can also apply predefined values, so audit and modification modes should be treated as different operations. Review the list and run an assessment before considering changes. The README says it was developed for English systems and warns that analysis can be incorrect in other languages. Match user and machine settings to the appropriate execution context described by the project.
