If you are having problems activating Windows 10, Server 2016, Windows 8, or Server 2012 one of these three solutions below should get you through:
Command Line to Launch Activation GUI:
This is handy if the GUI won’t start and you want to skip some steps to get it to work.
- click START (gets you to the tiles)
- type RUN
- type slui 3 and press ENTER
- yes, SLUI: which stands for SOFTWARE LICENSING USER INTERFACE
- SLUI 1 brings up the activation status window
- SLUI 2 brings up the activation window
- SLUI 3 brings up the CHANGE PRODUCT KEY window
- SLUI 4 brings up the CALL MICROSOFT & MANUALLY ACTIVATE window
- yes, SLUI: which stands for SOFTWARE LICENSING USER INTERFACE
- Type in your product key
- Have a nice day.
Command Line to Activate Windows Through Command Line:
- Launch a CMD as an Administrator
- Type: slmgr.vbs /ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
- Press Enter
If your key is valid and you are connected to the internet, it should activate within a second or two.
Call Microsoft Activation Center:
In Canada and the US, call the support line directly at 1 800-936-4900, otherwise, use this table of Microsoft Activation Phone Numbers to do the deed.

Thank you this save my day. Windows Server 2016 had some issues when you try to install using the GUI.

This helped me getting Win2016 activated by using SLUI 3.
Thanks a lot and have a great day!

I ran in to the same issue recently after building 3 Server 2016 VM’s using a template in vSphere 5.5 .
I tried DISM /Online /Set-Edition:ServerDatacenter /ProductKey: /AcceptEula with no luck.
DISM /online /Get-CurrentEdition – showed me were running ServerDatacenter edition.
Using just SLUI (no option) from cmd line or SLUI 3 came back with error saying it couldn’t find the KMS server.
I turned off Windows firewall and ran SLUI (no option) again and it worked.

You have to call Microsoft to activate offline. Here all of the regional numbers for Microsoft activations:

slui.exe 4 worked just fine for Windows Server 2016.

Hello, please which way can this server 2016 activate well?
Please help!!!
Ian Matthews · July 4, 2017 at 2:48 pm
Server 2016 should activate using the same processes. What are you seeing?

Pour une clé d’activation originale, je vous suggère le site “licence-activation”
J’en ai utilisé une clé de chez eux et ça marche parfaitement bien.
Ils répondent assez rapidement, et peuvent aussi vous assister par Teamviewer en cas de problème.
Je le recommande fortement.

TRANSLATION: For an original activation key, I suggest the ‘license activation’ site. I used a key from them and it works perfectly well. They respond pretty quickly, and can also assist you by Teamviewer if problem. I highly recommend it.

I believe this is the command you’re looking for.
dism /online /set-edition:ServerStandard /productkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /accepteula
Or if you installed Standard edition and you want to change it to datacenter
dism /online /set-edition:ServerDatacenter /productkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /accepteula
or you can also see what upgrades are available
dism /online /Get-TargetEditions

Server 2016 Datacenter gui would not allow product key change. The command line activation works fine.
