The primary difference between Autoruns64.exe Autoruns64a.exe is that the "a" version is the command-line (ASCII/CUI) version

If you need to use the command-line version, you typically use it to generate reports. For example, to export all entries to a text file, you would open a terminal and run: autoruns64a.exe -a > startup_report.txt Note on other versions Autoruns.exe : The 32-bit GUI version. Autorunsc.exe

If you try to run the "a" version on a standard Intel or AMD machine, it will likely fail with a "Not a valid Win32 application" error. What About Autoruns.exe (The Standard Version)? The standard Autoruns.exe is the original 32-bit binary.
