Is Windows Vista wiping out their out-of-box drivers? Here's how you preserve it!

  • Article

In your autounattend.xml, add the Microsoft-Windows-PnpSysprep component. Set the PersistAllDeviceInstalls value to True.

Here are the details.

PersistAllDeviceInstalls

PersistAllDeviceInstalls indicates whether all Plug and Play devices will be uninstalled during the generalize pass and then reinstalled during the specialize pass.

Typically, OEMs install the Windows reference image on computers that all use the same hardware. Because the hardware is the same on each computer, you can specify that Plug and Play information remains on the computer during the generalize pass. This eliminates the need to reinstall the information during the specialize pass. As a result, staged builds will typically take less time.

Values

true

Specifies that Plug and Play devices are not uninstalled during the generalize pass. The devices then do not need to be reinstalled during the specialize pass.

false

Specifies that Plug and Play devices are uninstalled during the generalize pass and then reinstalled during the specialize pass. This is the default value.
