child_process execFile / spawn throw non-descript exception on windows if exe requires elevation

Version: v6.5.0
Platform: Windows 10 (x64)
Subsystem: child_process

let cp = require('child_process');
let util = require('util');
try {
  cp.execFileSync('SomeTool.exe')
} catch (err) {
  console.log('err', util.inspect(err));
}

outputs

err { Error: spawnSync SomeTool.exe UNKNOWN

spawn generates the same error.

Obviously it would be better if this error was returned through the callback but I would also love to have a proper error code to react to the situation.
Not sure how execFile and spawn are implemented but it should be possible to report a proper errorcode as CreateProcess generates errorcode 740 if elevation is required.
