Fix Hyper-V Virtual Machine Startup Failure After Windows Update

**Hyper-V Virtual Machine Connection Error — Windows Host** A Virtual Machine Connection dialog box on host "WP-HOST" displays an error stating: *"Failed to start the virtual machine 'Ubuntu' because one of the Hyper-V components is not running."* The affected VM is identified by ID **B4253C26-8D33-4DAA-9624-EEB1BED97320**, and the VM status shown at the bottom of the window reads **"Off."**

**Screen displays a Command Prompt window running Coreinfo v3.6 on a system identified as a 12th Gen Intel Core i7-12700H (Intel64 Family 6 Model 154 Stepping 3, GenuineIntel), microcode signature 00000432.** The tool returns two error messages: **"Error loading driver"** and **"This driver has been blocked from loading,"** indicating the Coreinfo kernel driver was prevented from executing, likely due to a hypervisor or driver signing enforcement — consistent with the on-screen note warning that Coreinfo must run without a hypervisor for accurate results. A browser window is partially visible in the lower portion of the screen, showing Intel download pages for Processor Identification Utility, Processor Diagnostic Tool, and Arc Graphics Driver (Ubuntu).
