Some sophisticated malware checks if it is running under emulation by measuring instruction execution latency (RDTSC/RDTSCP differences). If you run autoruns64.exe on ARM64, the emulation layer changes timing. Malware that detects emulation might hide its startup entries. autoruns64a.exe avoids this detection. : Running the native ARM version ensures better

: This is the standard 64-bit version built for x64 (Intel or AMD) processors. It is the correct version for the vast majority of modern Windows desktop and laptop computers. | ✅ Yes, natively | ❌ No (only
