If you use the wrong one, the software will likely prompt you or fail to open. If you are unsure of your CPU type, right-click the Start menu, select "System," and check "System type." Other Files in the Pack

It remains in the package primarily to support older 32-bit versions of Windows or minimal environments where 64-bit support is absent. Which autoruns executable to use? - Microsoft Q&A

Paul Jackson 26. Feb 12, 2021, 3:23 AM. Hello, The Sysinternals Autoruns utility includes multiple executable files: autoruns.exe, Microsoft Learn

: This version of Autoruns is designed for 64-bit Windows operating systems. It provides comprehensive information on all auto-start programs, including those that are hidden or difficult to detect. Autoruns 64 allows users to inspect and manage auto-start entries from various locations, such as the registry, file system, and Windows services.

Scripted audits on lightweight ARM-based enterprise devices. Understanding Autoruns 64 ( autoruns64.exe ) autoruns 64 vs autoruns 64a

The primary difference between autoruns64.exe and autoruns64a.exe is the they are compiled to support: autoruns64.exe targets 64-bit Intel and AMD (x64) processors, while autoruns64a.exe targets 64-bit ARM (ARM64) processors.

The table below provides a quick, scannable breakdown of the active executables packaged within the official Sysinternals download. Executable Name Intended Architecture Common Devices / Hardware x64 (64-bit Intel / AMD) Graphical (GUI) Modern desktop PCs, standard laptops, gaming rigs. autoruns64a.exe ARM64 (64-bit ARM) Graphical (GUI) Microsoft Surface Pro (ARM), Snapdragon-powered laptops. autoruns.exe x86 (32-bit Intel / AMD) Graphical (GUI) Legacy PCs, older 32-bit Windows operating systems. autorunsc.exe x86 (32-bit Intel / AMD) Command-Line (CLI) Scripted environments, automated data collection. autorunsc64.exe x64 (64-bit Intel / AMD) Command-Line (CLI)

Running an x64 tool on an ARM machine requires emulation, which can be slower. autoruns64a.exe runs natively on ARM, offering better speed and accuracy in detecting ARM-specific startup items 1.2.3. Summary Table: Autoruns 64 vs. Autoruns 64a Autoruns64.exe Autoruns64a.exe Architecture x64 (Intel/AMD) ARM64 (Qualcomm, etc.) Primary Use Conventional PCs/Laptops Modern Windows on ARM Devices Performance Native on x64, Emulated on ARM Native on ARM, Won't run on x64 Frequency Used 95% of the time Niche (ARM only) Which One Should You Run? For 99% of computers: Run autoruns64.exe .

The primary difference between Autoruns 64 and Autoruns 64a lies in their handling of executable image path and command-line argument processing. If you use the wrong one, the software

Thus, if you are on ARM64 and double-click autoruns.exe (32-bit), it will still launch the emulated autoruns64.exe , not autoruns64a.exe . You must manually choose autoruns64a.exe .

Regardless of the version you choose, the tool's core purpose remains the same: it provides a comprehensive view of all programs, services, and drivers configured to start automatically on your system.

If you are currently setting up a diagnostic script or clean-up process, let me know:

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 - Microsoft Q&A Paul Jackson 26

If it says "64-bit operating system, ARM-based processor," .

: Although both tools offer comprehensive views into autorun configurations, Autoruns 64a might include specific updates or features. These could range from enhanced filtering capabilities, better handling of certain types of malware, to improved performance metrics.

. This version is specifically built for devices with ARM-based processors, such as the Microsoft Surface Pro X or newer laptops using Snapdragon chips. Microsoft Learn Which one should you use?

For driver forensics, always use the native build on ARM64. Emulation won’t miss drivers, but performance is worse.

For decades, Windows system administrators, forensic analysts, and power users have relied on as the ultimate utility for managing startup processes. Unlike the simplistic MSConfig or the rudimentary Task Manager Startup tab, Autoruns delves deep into the shadowy corners of the Windows Registry, scheduled tasks, services, drivers, and dozens of Auto-start Extensibility Points (ASEPs).

: This is the standard 64-bit version of the tool. It opens a window with tabs (Logon, Explorer, Services, etc.) and allows you to uncheck boxes to disable startup items visually. It is the best choice for most users performing manual system audits. Autoruns64a.exe (Command-Line) : The "a" stands for CUI (Console User Interface)
