To run a Windows 11 Enterprise Evaluation ISO on Hyper-V, you must first ensure the hypervisor is active and then configure a new virtual machine with at least 4GB of RAM and a dynamic hard disk. Import the evaluation ISO as a DVD drive, boot from it, and select the Enterprise edition during installation to activate the 180-day trial period without requiring a product key.
Prerequisites for Virtualization
Before creating any virtual machines, your host system must support hardware virtualization. This requires that Intel VT-x or AMD-V is enabled in your BIOS or UEFI settings. If this feature is disabled, Hyper-V will fail to start, and you will encounter errors when attempting to launch any virtual machine. You can verify if virtualization is enabled by opening Task Manager, navigating to the Performance tab, and checking the CPU section for "Virtualization: Enabled." If you are using Docker Desktop or other containerized applications, you may already have Hyper-V enabled. For those who need to enable it manually, refer to Hyper-V Virtualization Not Enabled: A Guide for Docker Desktop Users. This resource provides detailed steps for enabling the necessary features through PowerShell or the Windows Features dialog. Ensure that the "Hyper-V" role is installed and running before proceeding to create your virtual machine configuration.Creating the Virtual Machine
Open the Hyper-V Manager application from your Start menu. Right-click on your host computer name in the left pane and select "New," then choose "Virtual Machine." This launches the New Virtual Machine Wizard. In the first step, provide a name for the VM, such as "Win11Eval," and optionally specify a separate storage location for the virtual hard disk files. In the "Specify Generation" step, select Generation 2. Generation 2 VMs support UEFI firmware, Secure Boot, and SCSI controllers, which are required for Windows 11. Generation 1 VMs use legacy BIOS and do not meet the minimum requirements for Windows 11. Assign memory to the VM; Windows 11 requires a minimum of 4GB of RAM. It is advisable to assign 8GB if your host system has sufficient resources to ensure smooth performance during installation and usage. For the network connection, select an existing virtual switch that corresponds to your physical network adapter. This allows the VM to access the internet for updates and driver downloads. If no virtual switch exists, you can create one in the Virtual Switch Manager. Set the maximum number of snapshots to zero unless you plan to test different configurations, as snapshots consume significant disk space.Configuring Storage and Installation Media
During the "Connect Virtual Hard Disk" step, choose "Create a virtual hard disk" and set the size to at least 64GB, though 128GB is recommended for better long-term usability. Select VHD format and dynamic expansion to save host disk space initially. Complete the wizard to create the VM structure. Next, locate the Windows 11 Enterprise Evaluation ISO file on your host machine. In Hyper-V Manager, right-click the newly created VM and select "Settings." Under the "SCSI Controller" or "DVD Drive" section, change the media type to "Image file (.iso)" and browse to select your downloaded evaluation ISO. Ensure that the boot order places the DVD drive before the hard disk so that the VM boots from the installation media rather than an empty disk. It is also crucial to configure the security settings for Windows 11. In the VM settings, navigate to "Security" and enable "Enable Secure Boot." Additionally, under "Processor," ensure that "Expose virtualization extensions to the guest operating system" is checked if you plan to run nested virtualization inside the VM, though this is rarely needed for standard application testing.Installing Windows 11 Enterprise
Start the virtual machine. The VM should boot from the ISO and present the Windows Setup screen. Follow the prompts to select your language and time zone. When asked for the product key, click "I don't have a product key." This option is critical because evaluation editions do not require a license key to install. On the "Choose the operating system for installation" screen, you must carefully select "Windows 11 Enterprise Evaluation." Selecting any other edition, such as Pro or Education, will result in a standard licensed installation rather than the evaluation version. The evaluation edition comes with a specific expiration date, typically 180 days from the first activation. Proceed with the installation. Choose "Custom: Install Windows only (advanced)" for a clean install. Select the virtual hard disk you created earlier. The installation will copy files and restart several times. Once completed, you will be prompted to set up user accounts and privacy settings. Since this is an evaluation environment, you can disable telemetry and data collection options to reduce background activity. After setup, log in and verify the edition by opening Command Prompt and typingwinver or checking System Properties. It should explicitly state "Windows 11 Enterprise Evaluation." You can now proceed to install your legacy .NET Framework 4.8 applications. Note that evaluation licenses expire, and you will need to reinstall or upgrade to a licensed version after the trial period ends.

Frequently Asked Questions
Can I extend the Windows 11 Enterprise Evaluation period?
No, the 180-day evaluation period cannot be extended using commands or registry edits. Microsoft designed this limit to prevent indefinite use of the enterprise trial. You must either purchase a license or reinstall the OS from scratch to start a new evaluation cycle, though repeated reinstalls may trigger licensing restrictions.
Why does my VM fail to boot with Secure Boot enabled?
Secure Boot is mandatory for Windows 11, but some older ISOs or custom configurations may lack the correct digital signatures. Ensure you are using an official Microsoft evaluation ISO. If you modified the VM settings, verify that the TPM 2.0 emulator is enabled in the Security tab of the VM settings, as this is also required for secure boot validation.
Is it possible to use a Windows 11 Pro ISO instead?
You can use a Pro ISO, but it will not be an evaluation version unless you obtain a specific evaluation ISO from the Microsoft Volume Licensing Service Center. Standard retail Pro ISOs require a valid product key for activation. Using an evaluation ISO ensures you get the full enterprise feature set without immediate licensing costs.
How much RAM is actually needed for smooth performance?
While 4GB is the absolute minimum, 8GB is strongly recommended for Windows 11 to handle background services and application loading efficiently. Less than 4GB will cause significant swapping to the virtual hard disk, leading to poor responsiveness. Ensure your host machine has enough free RAM to allocate to the VM without impacting host stability.
What happens if I lose the evaluation license information?
The evaluation status is tied to the virtual hard disk and the initial installation timestamp. If you delete the VM and recreate it from the same ISO, you start a fresh evaluation period. However, if you attempt to migrate the VM to another host, the evaluation timer continues based on the original activation date, not the migration date.
