If all else fails, consider reinstalling the OMI client or relevant providers on the Win32 operating system.
If you are using the standard OMI build, the Win32_OperatingSystem class is implemented natively by a generic OMI provider. OMI expects a specific provider library (a shared object or DLL) to handle that class namespace. If the WMI compatibility provider is not registered or loaded, OMI looks for a native provider for Win32_OperatingSystem , finds nothing, and returns a null result.
for instance in result: print(instance.Caption, instance.Version)
If the repository is consistent but the specific class Win32_OperatingSystem is uniquely missing, you can manually re-register the core CIM and WMI schemas. Run these commands in an elevated Command Prompt: win32-operatingsystem result not found via omi
The error typically occurs during remote discovery (often in tools like FortiSIEM ) when the Open Management Infrastructure (OMI) client cannot retrieve data from the Windows Management Instrumentation (WMI) service on the target machine. 1. Authentication & Credentials
