Windows patch got failed

i got the message few patches got failed on few set of servers. I did not find failure reason in the client or application servers logs ?

Client logs just said command failed but not with the exact reason?

how to determine why few patches got failed on client machines?

So, when you open the Action and double click on a computer that Failed, what do you see as the Exit Code under the Summary section?

It says 3010 for all completed and failed server , that means restart needed, but even the client log does not tell the exact reason of patch failure , same exit code for all servers.

since it uses windows update service to install the patches you can see the error in the windows event log. I think it is under the setup log.

ok , i will check event log thank you.
