Hello Ramesh Babu,
Windows Server 2025 Standard is fully supported as a guest operating system for Hyper‑V and other virtualization platforms, but you must ensure that the host hardware and hypervisor are running a build that recognizes the new OS. If you are trying to create a VM and the option does not appear, it usually means the host is still on Windows Server 2022 or an older Hyper‑V Manager that has not yet been updated. In that case, you can still create the VM by selecting “Generation 2” and manually attaching the Windows Server 2025 ISO to the virtual DVD drive, then proceeding with installation. The guest OS type list in Hyper‑V is not critical; what matters is that the VM configuration (UEFI, Secure Boot, vTPM if required) matches the requirements of Server 2025.
If you are using VMware or another hypervisor, the same principle applies: choose the closest supported Windows Server version profile, then install Server 2025 from ISO. After installation, update VMware Tools or Hyper‑V Integration Services to ensure proper driver support. Microsoft’s official documentation confirms that Server 2025 Standard is supported in virtualized environments, but you must provision it manually until management tools are updated to list it explicitly.
