Q. I need to keep installed drivers on an OS even after running SYSPREP, how do I do this?

A. There may be scenarios where its critical drivers are not removed from an OS instance when SYSPREP is executed. To do this run the following prior to SYSPREP

  1. Move to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Sysprep\Settings\sppnp
  2. Select Edit - New DWORD value
  3. Enter a name of PersistAllDeviceInstalls
  4. Set to a value of 1 and click OK
