Autoruns 64 Vs Autoruns 64a _hot_ (2026)
Autoruns64.exe
The core difference between and Autoruns64a.exe is the processor architecture they are designed for. Use Autoruns64.exe for standard 64-bit Intel or AMD processors (x64), and use Autoruns64a.exe for 64-bit ARM processors. Architectural Compatibility
- Process Architecture: The process runs as an emulated x64 process.
- Registry View: Windows on ARM still uses Registry Redirection. The emulated x64 process sees the same logical view as a native x64 process on Intel hardware. It will correctly read
HKLM\SOFTWARE\Microsoft\... without the Wow6432Node redirect.
- File System: It accesses the native
C:\Program Files and C:\Program Files (x86) correctly.
- System Calls: Emulation translates x64 syscalls to ARM64 syscalls. Most work fine, but low-level operations (like parsing the boot execute registry keys or accessing raw NT objects) can have subtle latency or, in rare forensic cases, altered timing.
- Performance: Approximately 60-80% of native speed. Acceptable for occasional use, but painful for deep iterative analysis.
(console-based). It does not open a window. Instead, it is designed for use in scripts, batch files, or the Command Prompt/PowerShell to output startup data into text or CSV formats for analysis. Which one should you use? Use Autoruns64.exe autoruns 64 vs autoruns 64a
