In PS I had same problem .StartInfo.Hidden = $true was not enough !
It was not possible to use UseShellExecute $true since I needed to capture output.

I had to add also .StartInfo.CreateNoWindow = $true

And then it worked :)

I believe that UseShellExecute must be true to get the WindowStyle to work.

Ignore the MS documentation at ProcessWindowStyle Enumeration (System.Diagnostics)[^] which says the exact opposite!

It is also possible for an application to be written in such a way that it ignores a style request from the shell.
