  • Preventing criminals from taking control of your computer – Enabling memory integrity prevents third-party from getting unauthorized access to your PC, especially by hijacking lower-level drivers.
  • Enhancing overall security – HVCI technology improves overall security and protects your privacy on a Windows 11 PC.
