Running a Windows Server Evaluation (trial) version? You can convert it to the full, licensed edition in a couple of minutes using a single DISM command — no reinstall needed. This guide covers both the Standard and Datacenter editions for Windows Server 2016, 2019, 2022 and 2025.
Before You Start
You’ll need a genuine Windows Server product key that matches the edition you want (Standard or Datacenter). Make sure you know which edition your evaluation is running, then open PowerShell as administrator.
Check Your Current Edition (Optional)
To see your current edition, run:
DISM /Online /Get-CurrentEdition
Upgrade to Windows Server Standard
Run this command in PowerShell (as administrator):
DISM /Online /Set-Edition:ServerStandard /ProductKey:YOUR-KEY /AcceptEula
Replace YOUR-KEY with your product key, then restart when prompted.
Upgrade to Windows Server Datacenter
Run this command instead:
DISM /Online /Set-Edition:ServerDatacenter /ProductKey:YOUR-KEY /AcceptEula
Replace YOUR-KEY with your product key, then restart when prompted. After the restart, your server runs the full licensed edition, activated.
Trouble Upgrading?
If a command fails or activation doesn’t complete, open a support ticket and we’ll help during working hours. Every key includes a 7-day warranty.

Frequently Asked Questions
Which Windows Server versions does this work for?
Windows Server 2016, 2019, 2022 and 2025 evaluation editions.
Will I lose my data or roles?
No — this is an in-place edition conversion. Your installed roles, data and settings stay in place.
Can I switch from Datacenter back to Standard?
No. The Set-Edition command only moves an evaluation up to a full edition — it can’t downgrade Datacenter to Standard.
What if I get an error?
Open a support ticket within your 7-day warranty and we’ll send a fix or a new key.
