      • Hi,

        I’m trying to use System Center logs to automatically detect the update status of the computers that we have, these logs justs contains versions in the following format (10.0.18363, 10.0.17134…) and I would like to be able to mantain a CSV with each new version and build to match it. Where did you get this information from?

        Thanks

    Endre
