I used Bat to Exe Converter 3.2 to turn a batch script into an executable. The script downloaded and installed Microsoft Office, but I no longer remember the exact commands that worked. Is there a way to extract or recover the original .bat file from the EXE? If not, what is the simplest way to recreate the script? I'm new to this and got the original working mostly by trial and error.

PowerShell script-block logging probably won’t recover the original batch file. It only records PowerShell code when the executable actually launches powershell.exe or pwsh.exe, and logging must have been enabled before the script ran. Some converters package their own runtime and modules, so the commands may not appear in the normal PowerShell logs.
If the EXE was created with a PowerShell-based tool such as ps2exe, check that tool’s command-line help for an extraction option. This only applies if that specific converter was used; a regular batch-to-EXE wrapper may work differently.
Many batch-to-EXE tools package the original script inside a self-extracting archive. Try opening the EXE with an archive utility such as 7-Zip. If the script was included without encryption, you may be able to extract it directly.
You can also try an EXE resource extractor. Some converters store the batch file or related resources inside the executable, although the result depends on the converter’s options and whether the contents were compressed or encrypted.
Regardless of whether recovery works, keep the source script separately in the future— even a local folder with versioned backups is enough. An executable can be difficult or impossible to reverse back into the exact original batch file.
I’ll check the converter documentation and see whether it supports extracting the embedded script.
