How to Reset the Trial Period on Windows Server

Resetting the trial period on Windows Server, often referred to as “rearming,” can be done by using the slmgr.vbs script. This script can extend the trial period up to three times, giving you additional days before you need to activate the server. Here’s how you can do it:

Steps to Reset the Trial Period on Windows Server:

  • Open Command Prompt as Administrator: Press Win + R, type cmd, and press Ctrl + Shift + Enter to open the Command Prompt with administrative privileges.
  • Check the Current License Status: Enter the following command to check the current status of your license and display remaining time of your current trial period: slmgr.vbs /dli
  • Rearm the License: To reset the trial period, type the following command and press Enter: slmgr.vbs /rearm – You should see a message indicating that the command completed successfully and that you need to restart your computer.
  • Restart Your Server: Restart the server (required) to apply the changes. You can do this from the Command Prompt by typing: shutdown /r /t 0 – Alternatively, you can restart the server from the Start menu or Server Manager.
  • Verify the New Trial Period: After the server restarts, check the new trial period by running the command: slmgr.vbs /dli

Important Notes:

  • Limitations: You can only reset the trial period a limited number of times (usually three) before you need to activate the server with a valid product key.
  • Legal Considerations: Ensure that you comply with Microsoft’s licensing terms and conditions. Repeatedly resetting the trial period to avoid purchasing a license may violate the terms of service.
