N3rdy77 The local ADMX will update with the new policy once the September patch is taken. You should then be able to grab the ADMX/L files from such a device. As for your second point, I fully understand your concern. ConfigMgr is currently unable to manage the new proxy behavior setting. So in the case of managed environments where user proxy is needed, for the short term, you will need to set the desired proxy behavior via the registry directly. We hope to make this a more seamless process in future.
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\SetProxyBehaviorForUpdateDetection
- Value 0 – Only use system proxy
- Value 1 – Allow user proxy as fallback…
^ RichardSheath as you asked for the Regkey as well.
