What is it?

Windows Management Instrumentation (WMI) is Microsoft’s implementation of Web-Based Enterprise Management (WBEM), an industry initiative to provide a Common Information Model (CIM) for pretty much any information about a computer system.

The Python WMI module is a lightweight wrapper on top of the pywin32 extensions, and hides some of the messy plumbing needed to get Python to talk to the WMI API. It’s pure Python and has been tested against all versions of Python from 2.5 to 3.4. It should work with any recent version of pywin32.

Where do I get it?

• PyPI: https://pypi.python.org/pypi/WMI/

• Github: https://github.com/tjguk/wmi

How do I install it?

pip install wmi

How do I use it?

Have a look at the tutorial or the cookbook. As a quick taster, try this, to find all Automatic services which are not running and offer the option to restart each one:

import wmi

c = wmi.WMI()
for s in c.Win32_Service(StartMode="Auto", State="Stopped"):
    if raw_input("Restart %s? " % s.Caption).upper() == "Y":
        s.StartService()
