Hi all, As a result of some limitations with the Python WMI module, specifically performance and lack of support for Nano Server, here’s an alternative replacement that uses the newer Windows Management Infrastructure (MI) API in place of the slower COM interface used by WMI.py (https://pypi.python.org/pypi/WMI):
https://github.com/cloudbase/PyMI/tree/master/PyMI Pre-compiled wheels are available on Pypi: https://pypi.python.org/pypi/PyMI The package includes a native "mi" extension, providing a wrapper over the MI API and a "wmi" module which in turn wraps the lower level interface with an interface meant to be compatible with https://pypi.python.org/pypi/WMI. Benchmarks show rough execution speed improvements ranging from 50% on method calls to 500% and more on loops over query results. Early tests by just swapping the old WMI module with PyMI (without changes in the code) on the OpenStack Hyper-V Nova driver show a 50% performance improvement under heavy load. Supports Python 2.7 and 3.x on any x86 or x64 Windows version with the MI API, starting with Windows 7 (SP1) and Windows Server 2008 (SP2), including also Nano Server 2016. It does not use or require pywin32, making it much very easy to distribute. All basic features are already available on the current pre release, with events and async API support on the roadmap. WMI.py compatibility is currently limited to the features required by our target projects (e.g. OpenStack). A full test suite is planned to ensure increased compatibily and check for regressions.
