A cloud-native SIEM solution that provides intelligent security analytics and threat detection across systems
Hello @Adam Ring JIT
If your Sentinel workspace is in GCC High or DoD / Azure Government, this is most likely expected behavior.
Windows Update for Business reports aren't currently supported in GCC High/DoD, so the related UC* tables won't populate in Log Analytics. In that case, waiting longer won't resolve the issue.
For Windows Update compliance monitoring, you can consider alternatives such as Configuration Manager (SCCM/MECM), Azure Update Manager for supported server workloads, or a **custom compliance collection into Log Analytics and then create a Sentinel analytics rule to alert when compliance drops below 90%.
If you're using standard GCC rather than GCC High/DoD, it's worth confirming the exact cloud environment first, as support differs between them.
