Windows Update issues - Windows 10

I am currently troubleshooting an issue on PAN-OS 8.0.4 regarding the ability for Windows 10 / Windows Server 2016 to update via Windows Update.  Windows Update for Windows 7 is working fine, however any time I try to download updates on Windows 10 (Creators Update) it fails unless i add a the subnets below to exclude them from decryption.  As the App-ID ms-update does not decrypt by default, I'm wondering if there has been a change in data stream which is causing some Windows Update traffic to be identified as ssl rather than ms-update.  


Subnets excluded to get this to work:,




Has anyone else seen this issue as of recently?  I am trying to avoid opening up these entire subnets.

Perhaps this was fixed in 8.0.5


There is a fix listed



Fixed an issue where the firewall discarded sessions that required the TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 cipher for SSL decryption
