The cimwin32 provider is critical for Win32_OperatingSystem . To verify its registration:
# OMI CLI syntax omi query 'root/cimv2' "SELECT Name, Version, OSType FROM Win32_OperatingSystem"
If the repository is fine but data is still not found, the Win32_OperatingSystem provider might not be registered correctly. Open Command Prompt as Administrator. Navigate to the WMI folder: cd %windir%\system32\wbem Use code with caution. Re-register the CIM providers: win32operatingsystem result not found via omi new
The specific DLLs required to report Win32_OperatingSystem data are not registered or are damaged.
Before diving into complex registry fixes, you must rule out basic network blockages. OMI maps out requests across several operational ports that network firewalls or Windows Defender often block. The cimwin32 provider is critical for Win32_OperatingSystem
If local system tests fail even when using a local administrator account, the WMI repository on the target machine is likely corrupted. 1. Check Repository Health

There are two main approaches to rebuilding the repository: the "supported" method and the "unsupported" method. Both are widely used, but the unsupported method is not officially endorsed by Microsoft for some configurations.
Log into the shell of your Linux monitoring supervisor or collector node. Use standard networking tools to confirm that the ports required by OMI are reachable.
