In this blog post I will show you how to extend your trial period to three years. The evaluation version of Windows Server 2016 / 2022 is valid for 180 days and you can convert your trial version to retail.
After installing, you can try it out for 180 days. After 180 days you and your system will run into troubles for sure. But the good news is: You can extend the period to another 180 days up to 3 years.
Extending the Trial Period
First, take a look at your desktop. You should see the countdown in the corner down right.
Or start PowerShell and run slmgr.
slmgr -dlvPay attention to the Timebased activation expiration and the Remaining Windows rearm count. You can rearm the period 6 times. (180 days * 6 = 3 years).
When the period comes to an end, run slmgr -rearm to extend it by another 180 days.
slmgr -rearm
Next restart your computer.
Restart-ComputerOnce restarted, open PowerShell and check your settings.
slmgr -dli
Important Note
The evaluation version may not be used for commercial purposes. Have fun playing with the Windows Server 2016 Evaluation Version!
By the way: You can do the same with Windows 10711. But the Windows 10/11 Evaluation Version can be used only for 180 days in total.
