Autoruns 64 Vs Autoruns 64a

While both executables are built for 64-bit processors, they are designed for fundamentally different processor architectures. This leads to differences in compatibility and how they interact with the operating system.

Microsoft has aggressively pushed Windows on ARM. Devices like the Surface Pro X, Lenovo ThinkPad X13s, and the new Surface Laptop Studio 2 (ARM variant) run Windows 11 ARM64. These devices can run x86 and x64 applications through emulation (Prism), but native ARM64 applications run faster, use less battery, and have full access to the underlying hardware without emulation overhead.

Because it is compiled specifically for 64-bit Intel/AMD systems, it runs natively without needing any emulation.

: This version of Autoruns is similar to autoruns64 , but it has an additional feature. The "a" in autoruns64a stands for "alternate," and this version displays registry entries and file paths with their Wow6432Node redirected view. This essentially means that if you're looking at a 32-bit application running on a 64-bit system (which is common), autoruns64a will show you the registry entries as they appear to the 32-bit application. Devices like the Surface Pro X, Lenovo ThinkPad

For a standard Windows 10 or 11 installation on an Intel or AMD processor, you should use . If you happen to run the basic autoruns.exe (the 32-bit version) on a 64-bit system, it is designed to detect the architecture and automatically launch the 64-bit version for you.
