Challenges in Windows 11 Installing ASPI on Windows 11 presents two major hurdles: Core Isolation (HVCI) Incompatibility : Modern Windows security features like Memory Integrity often block older ASPI drivers (such as aspi32.sys GEARAspiWDM.sys ) because they do not meet current security standards.
