Various tools for file operations, such as access protection by encryption or copying and synchronizing (Product group: Security software & Suites)
Remember that not only company computers contain data that should be protected from unauthorized access. Through encryption, important files can also be protected on privately used computers with this collection of tools. Passwords, USB sticks, various chip cards or certificates can be used as keys. As additional security, a password scrambler prevents key loggers from reading the keyboard input. The data encrypted with AES or Blowfish can only be opened with the correct key. In addition, the software offers the possibility to sign files, create a backup or synchronize data. The software is operated directly in the Windows File Explorer or alternatively via an assistant
For a standard Windows installation on an Intel or AMD processor, you should use autoruns64.exe
If you are unsure, simply run . On most modern 64-bit systems, the tool is designed to detect your architecture and will often automatically relaunch the correct 64-bit version for you.
is the standard version for nearly all modern PCs using Intel Core or AMD Ryzen processors. autoruns64a.exe is a specialized build for the
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 autoruns 64 vs autoruns 64a
The key informative feature here is that autoruns64a helps in troubleshooting and understanding the interaction between 32-bit applications and the Windows registry on a 64-bit system. On 64-bit versions of Windows, 32-bit applications that access the registry are redirected to use the Wow6432Node. This means that instead of writing to HKEY_LOCAL_MACHINE\SOFTWARE\YourApp , they write to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\YourApp .
Paul Jackson 26. Feb 12, 2021, 3:23 AM. Hello, The Sysinternals Autoruns utility includes multiple executable files: autoruns.exe, Microsoft Learn Use Microsoft Autoruns to locate undetected malware
Look for either (use autoruns64.exe ) or "ARM-based processor" (use autoruns64a.exe ). Core Use Cases: What to Do Once Launched For a standard Windows installation on an Intel
They are not version upgrades; they are parallel builds for different CPU architectures. Both receive updates simultaneously when Mark Russinovich releases a new version (e.g., v14.10, v14.11).
If you attempt to load autoruns64a.exe on a traditional Intel or AMD platform, the execution will crash instantly. Your operating system will display a crash prompt stating that the file is not a valid Win32 application because the CPU physically cannot process ARM instruction code natively.
The primary difference between and Autoruns64a.exe is the underlying CPU architecture they are compiled to target. Autoruns64.exe is compiled specifically for 64-bit Intel and AMD processors (x64) , whereas Autoruns64a.exe is compiled natively for 64-bit ARM processors (ARM64) . autoruns64a
The main difference between and Autoruns64a.exe is the target processor architecture: Autoruns64.exe is compiled specifically for 64-bit Intel and AMD (x64) processors, while Autoruns64a.exe is compiled for 64-bit ARM (ARM64) processors. Running the wrong executable will result in poor performance through emulation or a total failure to launch.
If you use a 32-bit Autoruns on a 64-bit OS, you might miss malware hiding in native 64-bit startup locations. Hence, the need for a native 64-bit version became mandatory.
Finding hidden malware persistence mechanisms on x64 devices. Managing complex 64-bit kernel-mode drivers. Understanding Autoruns 64a ( autoruns64a.exe )
Autoruns 64a, on the other hand, is an alternate version of Autoruns 64. The "a" in 64a stands for "alternate." This version is also designed for 64-bit Windows systems but uses a different approach to gather information about startup entries. Autoruns 64a uses the Windows API, but it also employs additional techniques to gather more comprehensive information about startup entries, including:
If you are uncertain which file to open, you can identify your processor configuration by executing these steps: Press the to open the System Settings app. Click on System , then scroll down and select About .
