== Installing VirtualBox Guest Additions on Windows ==
As previously discussed, the VirtualBox Guest Additions reside in an ISO image file which is bundled with the VirtalBox software. This image file must be mounted as a virtual CD-ROM on the virtual machine on which the additions are to be installed. VirtualBox provides a shortcut to performing this task in form of the ''Devices->Install Guest Additions....'' menu option. When selected, this option mounts the ''VBoxGuestAdditions.iso'' as a virtual CD-ROM and, assuming that Autorun AutoPlay is enabled on the guest Windows operating system, the VirtualBox Guest Additions installer will automatically start. If Autorun AutoPlay is not enabled, navigate to the CD-ROM using Windows Explorer and double click on''VBoxWindowsAdditions.exe'' to initiate the installation process. Once invoked, the ''Sun xVM VirtualBox Guest Additions Setup Welcome'' screen will appear. Click ''Next >'' to proceed to the license scree, review the license and click ''I Agree'' to display the installation screen as illustrated below:  [[Image:virtualbox_guest_additions_install.jpg|Installing VirtualBox Guest Additions on a Windows guest]]  Either accept the default installation folder or browse to the desired location before clicking the ''Install'' button to initiate the installation process. The progress of the installation is communicate via a progress bar and a scrolling report of tasks as they are performed:  [[Image:virtualbox_guest_additions_installation_progress.jpg|The progress of a VirtualBox Guest Additions windows installation]]  Once the installation is complete, the guest operating system must be rebooted for the guest additions to take effect. The reboot may be initiated from the Setup screen, or performed manually at a later, more convenient time. == Manually Extracted the VirtualBox Windows Drivers from the Guest Additions == The VirtualBox Guest Additions installer automatically extracts and installs the VirtualBox device drivers. In some situations, it is possible that just the drivers, and none of the other guest addition features may be required. In this situation, perform the following steps to extract the device drivers: 1. Mount the VirtualBox Guest Additions CD-ROM following steps outlined previously 2. Open a command prompt window and change directory to the location of the guest additions virtual CD-ROM 3. Execute one of the following commands depending on the guest operating system architecture: ::* VBoxWindowsAdditions-x86.exe /extract /D=C:\VBoxDrivers ::* VBoxWindowsAdditions-amd64.exe /extract /D=C:\VBoxDrivers Note that the above commands extract the driver files into C:\VBoxDrivers\x86 and C:\VBoxDrivers\amd64 respectively. Alternate locations may be specified by modifying the ''/D='' directive accordingly.
