DoNotCleanUpNonPresentDevices

Updated: August 1, 2012

Applies To: Windows 7, Windows 8, Windows 8.1, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2

The DoNotCleanUpNonPresentDevices setting specifies whether plug and play information for devices that are not detected on the destination computer during the next specialize should remain on the computer.

This setting is useful for devices with a physical on/off switch. When a physical on/off switch is off, the device information may be removed during either the generalize or specialize configuration pass. However, when both PersistAllDeviceInstalls and DoNotCleanUpNonPresentDevices are set to true, the device information remains on the computer.

This list describes the process Windows® Setup uses to determine whether plug and play information remains on the computer, or is removed, or is removed and then re-initialized:

  • When PersistAllDeviceInstalls is set to true, then during the generalize configuration pass, plug and play device information remains on the computer.

    During the next specialize configuration pass:

    • Any plug and play devices that are detected are re-installed.

    • For plug and play devices that are not detected:

      • If DoNotCleanUpNonPresentDevices is set to true, the device information remains on the computer.

      • If DoNotCleanUpNonPresentDevices is set to false, the device information is removed from the computer.

  • When PersistAllDeviceInstalls is set to false, then during the generalize configuration pass, plug and play device information is removed from the computer.

    During the next specialize configuration pass:

    • Any plug and play devices that are detected are re-installed.

    • Any plug and play devices that are not detected remain uninstalled. The DoNotCleanUpNonPresentDevices setting will have no effect.

WarningWarning
Using the DoNotCleanUpNonPresentDevices setting can lead to the unnecessary storage of excess device state and contribute to slower boot times. For more information about maintaining driver configurations when capturing a Windows image, see this Microsoft Website.

 

True

Specifies that during the next specialize configuration pass:

plug and play devices that are not detected remain installed.

false

Specifies that during the next specialize configuration pass:

plug and play devices that are not detected are removed from the computer.

This is the default value.

generalize

noteNote
Though this setting is specified in the generalize configuration pass, it controls the behavior for the next specialize configuration pass.

For a list of the supported Windows editions and architectures that this component supports, see Microsoft-Windows-PnpSysprep.

The following XML output specifies that drivers for devices that are not on the destination computer remain installed during the generalize configuration pass and the next specialize configuration pass.

<PersistAllDeviceInstalls>true</PersistAllDeviceInstalls>
<DoNotCleanUpNonPresentDevices>true</DoNotCleanUpNonPresentDevices>
