About this tag
The vm compatibility tag on WindowsForum.com covers issues where Windows virtual machines fail to boot or hang after applying Microsoft updates, particularly in Azure and other virtualized environments. Recent discussions focus on critical bugs in Windows 11 24H2 and Windows Server 2025 triggered by July 2025 updates, as well as a May 2025 security update (KB5058405) causing boot failures with error 0xc0000098 and ACPI.sys errors. Microsoft released out-of-band patches like KB5063666 and KB5064489 to address these problems. Topics include Virtualization-Based Security (VBS) conflicts, recovery mode errors, and remediation strategies for IT administrators managing VM infrastructure.
