Win32_OperatingSystem class missing

Saturday, February 2nd, 2019

We were fortunate to not have an issue for the wannacry ransomware. It was time to make sure this this never happened. We have a script designed to tell us when a system lacked the patching it needed.

While running it on one system; I received a rather peculiar error:

Win32_OperatingSystem class missing

I tried all the usual repairs and and tried to rebuild the WMI repository. Still the error persisted.

The following commands solved this issue:

cd %windir%\system32\wbem
for /f %%s in ('dir /s /b *.mof *.mfl') do mofcomp %%s

Information came from the following Technet entry.
