: 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.
: 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.
A 32-bit application running on a 64-bit version of Windows cannot directly see the native 64-bit Registry hives. Windows uses to isolate 32-bit and 64-bit applications. For example:
Emulated applications sometimes struggle to read specific hardware-level registry entries or kernel-level drivers correctly. Using Autoruns64a.exe on an ARM device ensures that the software accurately detects every single startup item without emulation blind spots. 3. Cross-Platform Hard Blocks autoruns 64 vs autoruns 64a

In the intricate ecosystem of Windows system administration, few tools are as revered as Autoruns. Developed by Microsoft Sysinternals, this utility provides an unparalleled view into every process, driver, and registry key configured to launch during system startup. However, a peculiar nuance often confuses new users: the presence of two 64-bit executables— autoruns64.exe and autoruns64a.exe . While they share the same icon and core functionality, a deeper examination reveals a critical distinction rooted in Windows architecture and the evolution of system security.
The "" in the filename stands for ARM . This version is compiled natively for ARM64 processors.
