The cross-platform tool to execute PowerShell and command line remotely and locally.

Project description

PyPI version Build Status Coverage Status


The cross-platform tool to work with remote and local Windows OS.

PyWinOS uses the Windows Remote Manager (WinRM) service. It can establish connection to a remote server based on Windows OS and execute commands:

  • PowerShell
  • Command line
  • WMI.

It can execute commands locally using subprocess and command-line too.

For more information on WinRM, please visit Microsoft’s WinRM site It based on pywinrm.

PyWinOS (main methods) returns WinResponse object with properties:

  • exited: Exit code (int)
  • stdout: standard output stream (converted to dict if got appropriate content)
  • stderr: standard err stream
  • ok: Is exit code == 0 (bool)


For most users, the recommended method to install is via pip:

pip install pywinos

or from source:

python install


from pywinos import WinOSClient

Usage (remote server)

Run PowerShell:

from pywinos import WinOSClient

tool = WinOSClient(host='', username='administrator', password='qqq123aaa', log_enabled=True)
response = tool.run_ps(command='$PSVersionTable.PSVersion')

# 2022-07-17 23:04:22 | INFO      | WinOSClient         232 |    PS | $PSVersionTable.PSVersion
# 2022-07-17 23:04:23 | INFO      | WinOSClient         264 |    PS | 0:

from pywinos import WinOSClient

tool = WinOSClient(host='', username='administrator', password='qqq123aaa', log_enabled=True)
response = tool.run_ps('Get-Service -Name "ALG" | ConvertTo-Json')

# 2022-07-18 21:02:02 | INFO      | WinOSClient         220 |    | PS  | Get-Service -Name "ALG" | ConvertTo-Json -Depth 1
# 2022-07-18 21:02:03 | INFO      | WinOSClient         252 |    | PS  | 0:
# 	{'CanPauseAndContinue': False, 'CanShutdown': False, 'CanStop': False, 'DisplayName': 'App...

# {'CanPauseAndContinue': False, 'CanShutdown': False, 'CanStop': False, 'DisplayName': 'Application Layer Gatew...}

# None

# True

Run command line:

from pywinos import WinOSClient

tool = WinOSClient('', 'administrator', 'P@ssw0rd', log_enabled=False)
response = tool.run_cmd(command='whoami')

# 2022-07-17 23:06:46 | INFO      | WinOSClient         232 |    CMD | whoami
# 2022-07-17 23:06:46 | INFO      | WinOSClient         264 |    CMD | 0:
# 	autovm1\administrator

Instance of a WinResponse can be pretty printed

from pywinos import WinOSClient

client = WinOSClient('', 'administrator', 'zzz123ZZZ', log_enabled=True, log_level='DEBUG')
result = client.is_service_running('alg')
  "exit_code": 0,
  "ok": true,
  "stdout": "autovm1\\administrator",
  "stderr": "",
  "cmd": "whoami",
  "raw": "<Responsecode0, out b'autovm1\\administrato', err b''>"
  • exit_code: Exit code (int)
  • ok: Is exit code == 0 (bool)
  • stdout: standard output stream
  • stderr: standard err stream
  • cmd: Command sent
  • raw: Response class from WinRM

Main low-level methods to work with local/remote Windows OS:

  • run_cmd
  • run_cmd_local
  • run_ps
  • run_ps_local

High-level methods:

  • Use list_all_methods() to get list of all methods.
