Step 4: 

Use any script editor and open GPOPack.wsf from Windows 8 GPO folder and look for the section where it validates the Windows 8 and edit the file as per the below instruction and save it.

Modify the lines to the following

    If(Left(strOpVer,3) = "6.2") and (strProductType = "1") then
   strOS = "Win8"
    Elseif(Left(strOpVer,3) = "6.1") and (strProductType <> "1") then
   strOS = "WS08R2"

Step 5:

Now you are ready with your default base line package. Copy this back to the Template folder in your workbench

Step 6:

Update GPOPackPath variable in the customsettings.ini file to point to this new GPO Pack

GPOPackPath = Win8RTM-MDTGPOPack

If you do not want to apply any GPO Packs then task sequence step can be skipped by setting the variable ApplyGPOPack to NO in customsettings.ini.

 

Step 7:

Open the MDT Task sequence , Make sure you have the step exist to launch the ZTIApplyGPOPack.wsf called. ( This is part of default client task sequence) or you can manually add a “Run Command Line” Step after Restore Groups

There is no need to edit ZTIApplyGPOPack.wsf since the entry for Windows 8 is already present
