MDT and MAK product key

Question

We are using MDT2010 and now MDT2013 for years now. I must make a new deploymentshare for 64 bit Windows 7 but cannot find in my documentation where to put the MAK key in MDT for later activation when Windows 7 is deployed.
I have looked in MDT where i have put the MAK key but cannot find it anywhere, not in custom settings / bootstrap.ini, any task sequence etc.
Searching the Internet the MAk key must be put when importing a operating system into MDt but i have never done that. After deploying Windows 7 to a client i activate the system at once, the MAk product key is somewhere stored, i have done that myself but
do not know where.....
Is there some standard point where i must put the MAK key in MDT, when syprepping and capture  task sequence or in a deployment task sequence or in the customsettings.ini / bootstrap.ini within the capture deployment or deploymentshare?
This is neccessairy because i want to capture and deploy a new Windows 7 but now 64 bit in MDT so the key must be put somewhere..
It can be put in the virtual machine that is goiing to be captured. After installing WIndows in the VM put in the product key, but maybe this key is lost when importing and deploying thru MDT...
It can be somewhere in the sysprep and capture task sequence although i cannot find it
In the deployments task sequence cannot find them here also
Int he rules.ini or bootstrap.ini of the captureshare or deploymentshare but here also not found..

When you sysprep the machine the license will be removed. You can either add it to the unattend file or you can write a script to install the key and force it activate Windows, your choice. The easiest would be to just add the key to the unattend.
I have a script for machines that will be off campus and out of reach of our KMS server. In this example I install the Office MAK and activate it, but as for Windows I just added that key to the unattend. Specialize-->Microsoft-Windows-Shell-Setup
oShell.Run("cscript " & oENV("ProgramFiles(x86)") & "\Microsoft Office\Office15\ospp.vbs /inpkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX")
oShell.Run("cscript " & oENV("ProgramFiles(x86)") & "\Microsoft Office\Office15\ospp.vbs /act"),0,True
