Microsoft invites everyone to get acquainted with the features of the server platform using trial versions of Windows Server 2019 or Windows Server 2016 (StandardEvaluation or DatacenterEvaluation). By filling out a short form, you can download Windows Server 2019 on-premises Free Trial or Windows Server 2016 Evaluation for free here. After installing Windows Server Evaluation, you have 180 days to test its capabilities. During this time, the full functionality of Windows Server 2019/2016/2022 is available to you.
When using the Evaluation version of Windows Server, the desktop displays the current build and the time until the end of the grace period (
Windows License valid for 180 days).
Name: Windows, ServerStandardEval edition Description: Windows Operating System, TIMEBASED_EVAL channel License Status: Licensed Timebased activation expiration: xx min (xx days)
You can see the product name, description (TIMEBASED_EVAL channel), and activation expiration time.
You can extend your Windows Server trial period up to 5 times. Thus, the maximum lifespan of Windows Server Free Trial can be extended to 3 years =
180 days * 6. However, under the terms of using Evaluation versions of Microsoft, you shouldn’t use the trial version for commercial purposes or productive tasks.
After the expiration of the trial period, Windows Server starts requiring activation and shutting down every hour with the following events in the Event Viewer:

If you try to specify the KMS, Retail, or MAK product key on Windows Server Evaluation edition, the following warning appears: “This edition cannot be upgraded”.
When you try to install the retail key using the
slmgr.vbs tool (
slmgr /ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx) you will receive the error:
Error: 0xC004F069. On a computer running Microsoft Windows non-core edition, run ‘slui.exe 0xC004F069’ to display the error text.
If you run the specified command, a description of the error will appear:

As you can see, the current ServerStandardEval edition has been upgraded to the following Windows Server 2016 / Windows Server 2019 editions: ServerDatacenter or ServerStandard.
Upgrade Restrictions for Windows Server Evaluation
Here are some upgrade restrictions that you need to know before converting Windows Server Evaluation to the full edition:
- You cannot upgrade a server with an Active Directory Domain Service domain controller role. It will first have to be demoted to a member server (check that FSMO AD roles are not running on this DC, transfer them to other domain controllers if necessary);
- If NIC Teaming is configured on the server, it must be disabled before upgrading;
- Windows Server Eval Datacenter cannot be upgraded to Windows Server Standard Full. First, you need to upgrade your edition to Windows Server Datacenter Full, and then use a little trick to downgrade the Windows Server edition (check the link at the end of the article);
- You can convert both the full GUI version of Windows Server and the Windows Server Core (converting the trial version of Server Core is supported starting from the release of Windows Server 2016 14393.0.161119-1705.RS1_REFRESH).
Windows Server 2016: Converting Evaluation to Licensed Version
To upgrade Windows Server Evaluation to a full version, you need to use the public KMS (GVLK) key for Windows Server 2016. The conversion is performed via the command prompt using the built-in DISM tool. For example, to upgrade your Eval edition to the Retail version of Windows Server 2016 Standard, use the command:
dism /online /set-edition:ServerStandard /productkey:WC2BQ-8NRM3-FDDYY-2BFGV-KHKQY /accepteula
If you specify your retail or MAK key instead of a public GVLK key in the DISM command, an error will appear:
Error 1168 The specified product key could not be validated. Check that the specified product key is valid and that it matches the target edition.
Always use the Microsoft GVLK key when upgrading the Windows Server edition. You will later replace it with your own product key.
DISM /set-editioncommand, it hangs by 10%. In this case, we recommend you find and stop the Software Protection Service (
Stop-Service sppsvc -Force) and disable Internet access (you can even disconnect the Ethernet LAN cable).
After you run this command, wait for the message
Command completed successfully (in some cases it may take several hours!!!). After that restart your server and make sure you have a full Standard edition installed.
To upgrade Windows Server 2016 Eval to the Datacenter edition, you need to use another GVLK key. The command will look like this:
DISM /online /Set-Edition:ServerDatacenter /ProductKey:CB7KF-BWN84-R7R2Y-793K2-8XDDG /AcceptEula
slmgr /ipk WC2BQ-8NRM3-FDDYY-2BFGV-KHKQY (this is the GVLK key for Windows Server 2016 Standard, another product key is used for Datacenter, it is listed above)
If there is no KMS server, you can specify your MAK or Retail product key for Windows Server and activate the OS as usual: via the Internet or by phone.
Remove the current key:
Enter your MAK or retail product key:
slmgr.vbs /ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
Activate a Windows Server instance:
