Have you ever used an evaluation license within Windows Server and had it expire on you just before you have finished your project? Yip, I think we've all hit that snag every so often. 

In this blog post, I want to cover how you extend the Windows evaluation period for the server. 

## Windows Server 2016/2019/2022

To reactivate your trial license, you need to open a command prompt; this can be something like Command Prompt or [PowerShell](https://www.techielass.com/tag/powershell). 

The Software Licensing Management Tool (SLMGR) tool is the one you want to invoke. There are a lot of switches with this tool. The ones we are concerned with are: 

```PowerShell
slmgr.vbs -dlv

```

SLMGR verbose information

This command displays the current license information with activation information as well. It's a pretty helpful command and provides a great deal of information. 

The second command is the one that rearms the license: 

```PowerShell
slmgr.vbs -rearm

```

SLMGR rearm

Be sure to **reboot** the server after this command to initiate the changes. Once you have done that, you can again use the **slmgr.vbs -dlv** command to check the licensing status and how many rearms you have left. 

This syntax will work on older versions of Windows Server as well.
