Unable to Activate Windows 10 With Post Installation Task (4272795)

A captured Windows 10 image that is not using a MAK key nor a KMS Server for activation, instead it was set to "Activate Windows Later" during the Sysprep Process, once deployed is not activating Windows with a Post Installation Task that used to work in Windows 7.

There are 2 possible solutions for this situation:

1. Capture the image again disabling UAC.
   • Sysprep the image again with the Sysprep Creator and under Step 2 check the option for "Disable User Access Control (UAC)"
   • Capture the image, add the Post Installation Task to the image and deploy.
2. Add BAT File to the Post Installation Task, so it can Elevate the BAT Script to activate windows.
   • Create a new bat file with this parameters: powershell.exe -Command "Start-Process Activation.bat -Verb RunAs" and name it Elevate.bat.
     • This command will call Powershell.exe to run the Activation.bat as an Administrator. This will use the local administrator user to elevate the command.
   • Create a new bat file with this parameters and name it Activation.bat:
     cscript C:\Windows\System32\slmgr.vbs -IPK XXXX-XXXX-XXXX-XXXX
     cscript C:\Windows\System32\slmgr.vbs -ATO
     • These are the parameters used on the batch file for your Windows Activation Post Installation Task. You can either create a new batch file or rename the original, but you will need to add the name to the Elevate.bat on the parameters.
   • Add these two .bat files to a zip using Windows Zip Utility.
     • Other compressing tool may not work correctly with the KSDA.
   • Create a New Application Post Installation Task and upload as dependencies the zip file containing the .bat files.
   • On the parameters field put Elevate.bat
   • Add the Post Installation Task to the image and deploy it.
3. *NOTE: This step will only work if Powershell is installed/enabled on the sysprepd' image.
   *NOTE: You can either capture an image with Powershell installed/enabled or install it/enable it with a Post Installation Task.
