Firstly, please make sure its dependencies services(DCOM Server Process Launcher and
RPC Endpoint Mapper) running fine.
If both are running fine, we could try to reset the Windows Update Components to check the result.
Yes, both DCOM Server Process Launcher and RPC Endpoint Mapper are running and RPC is running too
When I reset WU components the following errors occurs:
1. At the step 4 catroot2 folder cannot be renamed because it's is locked by some process (I dont know which). I think that kb article is for windows versions prior 10 and for win10 another additional services should be stopped to unlock catroot2 folder
2. At step 6 regsvr32 outs errors for some dlls:
<style type="text/css">P { margin-bottom: 0.21cm; }</style>
DLLRegisterServer entry point not found:
mshtml.dll
shdocvw.dll
