Hi 辉 周,

Thanks for your post. Based on my research, 0x80073701 = ERROR_SXS_ASSEMBLY_MISSING which means there are some system files are missing, which caused the update installation failure. Based on my research, you can use the check tool to see if you have met the requirements: Windows 10 Hyper-V System Requirements | Microsoft Learn

Also, please confirmed that you enabled Virtualization in the BIOS on the physical server.

Best Regards,

Ian Xue
