"BUG by Design" in Windows Server 2019 (Windows Updates)
That is a bug in Windows Server 2019!
We have Group Policy for Windows Updates and use in our infrastracture WSUS. According to Group Policy, the updates will be downloaded to the system, and then an administrator will install manually the downloaded updates.
We tested Windows Updates onsome Windows Server 2019 machines.
If the click "Check for updates", then the updates will be downloaded and automatically installed!!! That is fatal!
If I check "View configured update policy", then our policy are listed for the updates. It seems all are correct.
"BUG by Design"?
We have the same Policy-settings and the Server do not install updates automatically! So maybe there is a wrong setting? Did you already check settings in registry? (HKLM\Policies\Microsoft\Windows\WindowsUpdate)
