Windows 10: Clearing "Installed product key successfully message" through cmd line

I'm deploying our Windows 10 company image through MDT. One of the steps i do is enter the windows key through a command line custom task. The problem I run into is that I keep getting the "Installed product key successfully message" dialog box to come up which stalls the rest of my task sequence and forces user intervention.


The command line I'm using - which I thought would prevent any confirmation boxes - is:

slmgr.vbs -ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /VERYSILENT /SUPPRESSMSGBOXES

Unfortunately this doesn't seem to work. Does anyone have any suggestions on how I can clear this message automatically, suppress it from even popping up or if I'm doing something wrong, what the correct command is?

Any help would be appreciated.

Thanks

:)

Hi Muhammad,

Just to follow up, is your Windows 10 Pro already activated?

Keep us posted.

 

I'm not seing the /verysilent /suppressmsgboxes in the slmgr /? help window.

What about adding '>C:\temp.txt' without the quotes to the end to dump the message to a text file then delete the text file?

 

Can you still pipe output to NULL like you could in DOS?

If so, slmgr.vbs -ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX > NULL may work.
