# Detailed description

Trying to start localstack (0.11.6) that's been downloaded on a Windows 10 machine with the help of pip. In fact, trying to run just: `localstack`, which should print the usage, results in the same output.

Output from a PowerShell prompt:

```
P:\>python C:\Users\user\AppData\Local\Programs\Python\Python39\Scripts\\localstack start
'uname' is not recognized as an internal or external command,
operable program or batch file.
Traceback (most recent call last):
  File "C:\Users\user\AppData\Local\Programs\Python\Python39\Scripts\localstack", line 18, in <module>
    cli.main()
  File "C:\Users\user\AppData\Local\Programs\Python\Python39\lib\site-packages\localstack\utils\cli.py", line 130, in main
    bootstrap.load_plugins(scope=bootstrap.PLUGIN_SCOPE_COMMANDS)
  File "C:\Users\user\AppData\Local\Programs\Python\Python39\lib\site-packages\localstack\utils\analytics\profiler.py", line 153, in wrapped

  File "C:\Users\user\AppData\Local\Programs\Python\Python39\lib\site-packages\localstack\utils\common.py", line 4, in <module>
    import pwd
ModuleNotFoundError: No module named 'pwd'
```

From my understanding windows might not be compatible with the `pwd` module.

Official Python docs:

> This module provides access to the Unix user account and password database. It is available on all Unix versions.

But this is just guesswork...

I've tried with lower version of localstack (0.11.2 and 0.11.5) on the same setup, and they work just fine.
