kb5099536

The kb5099536 tag covers discussion of the July 14, 2026 update for Windows Server 2025, which advances systems to OS Build 26100.33158. Current coverage focuses on physical servers using LSI MegaRAID 9361-class controllers with CacheCade enabled, following a field report of possible post-update recovery loops. The reported issue has not been confirmed by Microsoft, but the discussion recommends treating affected hosts as a separate deployment ring. Administrators may hold the update on those systems or schedule installation during a maintenance window that allows offline boot checks and storage validation. The tag is therefore centered on cautious update deployment and hardware-specific recovery testing.
