Microsoft’s evaluation project gives people the opportunity to try out products such as Windows Server 2016 and 2019. If you want to unlock the full versions, you must purchase a product key and activate your server system through a valid method. This article focuses on using the DISM command to convert Windows Server from the Evaluation version into the Full version.
Converting Windows Server from Evaluation to Full licensed version
This is a complete guide to convert your Evaluation edition of Windows Server into a Full, properly licensed version using a legal product key and the DISM command. Make sure to accurately follow our steps in order to achieve the desired end result.
Note: You might be required to have access to an administrator account to perform all of the steps described below. If the account you’re currently using doesn’t have administrative permissions, make sure to change this in your settings or contact your IT professional.
Let’s get started with the guide!
- Make sure you have your product key ready. You can purchase product keys from various online retailers, or the official Microsoft website. You should receive a 25 character long code that’s used to convert your system from Evaluation to the Full version.
- Start your system and open the Command Prompt in one of the following ways:
- Using the search function in your taskbar, look up Command Prompt. When you see it in the results, right-click on it and choose Run as Administrator.
- Press the Windows + R keys on your keyboard to bring up the Run utility. Type in “cmd” and press the Ctrl + Shift + Enter keys on your keyboard. Doing so, you’re launching the Command Prompt with administrative permissions.
- Press the Windows + X keyboard shortcut, then select Command Prompt (Admin).
- If prompted, click Yes to allow the Command Prompt to make changes on your device. You might be required to input the administrator password as well.
- Check the current version of your system using the following command: DISM /Online /Get-CurrentEdition
- Next, enter this command into the Command Prompt and press the Enter key. Make sure to read our explanation below the command and replace the marked areas as needed: DISM /online /Set-Edition: ServerEdition /ProductKey: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula
- ServerEdition depends on what product key you have:
- If you’re upgrading to the Standard edition, replace ServerEdition with ServerStandard.
- If you’re upgrading to the Datacenter edition, replace ServerEdition with ServerDatacenter.
- The string of X characters is the place for your product key mentioned in Step 1.
- Wait for the loading to complete. This may take a long time – ensure that you don’t turn your computer off while the process is ongoing.
- Your computer may restart on its own several times, or prompt you for permission to restart — in this case, press the Y button on your keyboard.
- Once the process is complete, you can check if your Windows Server is out of the Evaluation edition by following these simple steps:
- Open the File Explorer from your taskbar.
- Right-click on This PC.
- Choose Properties from the context menu.
- Check the Windows edition section to see if the conversion was successful.
Why Use DISM to Convert Windows Server Evaluation to Full Version?
DISM (Deployment Image Servicing and Management) is Microsoft’s built-in command-line tool for servicing and managing Windows images. One of its most useful capabilities is converting Windows Server Evaluation editions into fully licensed versions without requiring a complete operating system reinstallation.
For IT administrators and businesses, this approach significantly reduces downtime while preserving installed applications, server roles, configurations, and existing data. Instead of rebuilding an entire server environment, administrators can simply apply a valid product key and perform the edition upgrade through DISM, making it one of the fastest and most reliable methods available.
Things to Check Before Starting the Conversion
Before converting your Windows Server Evaluation edition, it is recommended to verify that your system is properly prepared. Ensure that you have a valid product key matching the target edition, administrative privileges, and a recent backup of critical server data.
It is also advisable to install any pending Windows updates before beginning the conversion process. Keeping the server fully updated minimizes the risk of compatibility issues and helps ensure that the DISM command completes successfully. Additionally, verify that your hardware resources are sufficient and avoid interrupting the process once it has started.
Common Reasons Why Windows Server Evaluation Conversion Fails
Although the DISM conversion process is generally straightforward, certain issues can prevent a successful upgrade. The most common causes include using an incorrect product key, specifying the wrong target edition, insufficient administrator permissions, or attempting to convert to an unsupported edition.
Another common issue occurs when administrators skip the step of checking available target editions using the DISM Get-TargetEditions command. Verifying supported upgrade paths before starting can help avoid errors and ensure a smooth transition from the Evaluation edition to a fully licensed Windows Server environment.
Benefits After Converting to a Full Windows Server License
Once the conversion process is completed successfully, organizations gain access to a fully licensed Windows Server environment without the limitations associated with evaluation editions. This includes continued security updates, long-term production use, compliance with licensing requirements, and uninterrupted access to critical server workloads.
A licensed server environment also eliminates concerns about evaluation expiration periods and allows businesses to confidently deploy Windows Server for production applications, virtualization workloads, file services, and enterprise infrastructure management.
Frequently Asked Questions About Windows Server Evaluation Conversion
Will converting Windows Server Evaluation to Full Version remove my applications?
No. Converting Windows Server from the Evaluation edition to a fully licensed version using DISM is designed to preserve installed applications, server roles, settings, and existing configurations. However, creating a full system backup before making any major licensing changes is always recommended.
Will my files and data remain after the conversion process?
Yes. The conversion process does not normally affect user data, databases, shared folders, or business applications. Your files should remain intact throughout the edition upgrade process.
Does Windows Server restart during the conversion?
Yes. Windows Server may automatically restart one or more times while applying the new edition and licensing changes. These restarts are part of the normal conversion process and should not be interrupted.
How long does it take to convert Windows Server Evaluation to a licensed version?
The conversion time varies depending on your server hardware, installed roles, and system performance. In most cases, the process is completed within 15 to 60 minutes.
Can I convert Windows Server Evaluation to Datacenter Edition?
Yes. If your server supports the target edition and you have a valid Datacenter product key, you can use the DISM command to upgrade directly from the Evaluation edition to Windows Server Datacenter.
How can I verify that the conversion was successful?
After the process is complete, you can run the DISM /Online /Get-CurrentEdition command or check the Windows edition information in System Properties to confirm that the server is no longer running the Evaluation edition.
What happens if I use the wrong product key during conversion?
If the product key does not match the selected target edition, the conversion process will fail and display an error message. Always verify that the product key corresponds to the edition you intend to install.
Do I need internet access to convert Windows Server Evaluation?
Internet access is not always required for the edition conversion itself. However, an internet connection may be needed later to complete activation, validate licensing, or download updates.
We hope that our article was able to help you convert your Evaluation version of Windows Server to the full version, complete with a legal license. Enjoy your server to the fullest, without any limitations insight.
