pnputil a a:\usbcam.inf Adds the package specified by Usbcam .inf into the driver store . This command requires you to run PnPutil .exe with administrator credentials but does not require that the device be connected to the computer . pnputil a path_to_INF_files\*.inf Stages multiple drivers using a single command or script . You must first place all driver packages into the central directory referenced in the command . pnputil e Enumerates all packages that have been published (staged) in the driver store . If no third-party drivers are published, it will return the error No published driver packages were found on the system . pnputil.exe d INF_name Deletes the specified package from the driver store, provided that no currently installed device is using the driver . This command also purges the index of any reference to the driver package being removed . Note that this INF_name is the published name of a third-party package in the driver store, as returned by the pnputil e command . This command requires you to run Pnputil .exe with administrator credentials . pnputil.exe f d INF_name Forcibly deletes the specified driver package . (You can use this if necessary to remove a package associated with a device that is physically installed in the system or when using d alone returns an error accessing the package . However, this is not recommended because doing this causes problems for the device[s] that are still left referencing the driver package that was forcibly removed .) Note that this INF_name is the published name of a third-party package in the driver store, as returned by the pnputil e command . This command requires you to run Pnputil .exe with administrator credentials .

Note that when using pnputil a to stage multiple drivers using a single command or script, the command or script can sometimes halt before finishing . This can occur if either of the following conditions is true:

If this problem occurs, troubleshoot the issue by stepping through the command or script to identify the problem driver and replace it with an updated driver designed for Windows 7 .

The new DISM command-line tool (DISM .exe) is included both in a default install of Windows 7 and in the Windows AIK 2 .0 . DISM .exe can be used to service both online (running) and offline Windows images by adding or removing device drivers, hotfixes, and operating system packages; configuring international settings; and upgrading a Windows installation to a different edition, such as from Business to Ultimate . DISM .exe can be used to service images in the following versions of Windows:

Windows Vista Service Pack 1 (SP1) or later versions Windows Server 2008 Windows 7 Windows Server 2008 R2

To service an offline Windows image using a technician computer on which Windows AIK 2 .0 has been installed, you use DISM .exe to do the following:

1. 2. 3.

Servicing an online Windows image, however, does not require mounting or unmounting the image because the operating system is already running . In addition, any changes made to the driver store (for example, by adding or removing a device driver) are committed immediately when a DISM command is executed to service an online image . To indicate that the current running image is to be serviced, specify the /online parameter in the DISM command . For example, the following DISM command enumerates a list of installed out-of-box device drivers on a running Windows 7 system .
