Re: Signature update finished. No updates needed. Co-managed device
2289820 We have found some more information on this. We can confirm that the issue is caused by the registry settings in HKLM:\Software\policies\Microsoft\Windows\WindowsUpdate There you have 4 keys: SetPolicyDrivenUpdateSourceForDriverUpdates SetPolicyDrivenUpdateSourceForFeatureUpdates SetPolicyDrivenUpdateSourceForOtherUpdates SetPolicyDrivenUpdateSourceForQualityUpdates All of which are set to 1 by Configuration Manager if you have Co-Management enabled and the Workloads for Windows Update policies and Office Click-To-Run set to Configuration Manager (or Intune Pilot and the devices having the issues are not in that Pilot collection). Setting SetPolicyDrivenUpdateSourceForOtherUpdates to 0, restarting the Windows Update service and triggering the signature Update by any means, instantly updates your signatures. However according to this documentation: https://learn.microsoft.com/en-us/windows/deployment/update/update-other-microsoft-products, this also sets the updates for other products, which for us is a no go. Currently we are checking if setting the Defender Preference OobeEnableRtpAndSigUpdate to true with PowerShell and rebooting the device fixes the issue. Set-MpPreference -OobeEnableRtpAndSigUpdate $true This was suggested by MS support. I will get back to you once we have reliable results.641Views0likes2Comments
