To avoid popups when performing an unattended installation of the Oracle VM VirtualBox Guest Additions, the code signing certificates used to sign the drivers needs to be installed in the correct certificate stores on the guest operating system. Failure to do this will cause a typical Windows installation to display multiple dialogs asking whether you want to install a particular driver.
On some legacy Windows versions, such as Windows 2000 and Windows XP, the user intervention popups mentioned above are always displayed, even after importing the Oracle certificates.

Aero / Direct3D on the guest. Instead, the WDDM graphics
driver needs to be installed. To select this driver by

For Windows Aero to run correctly on a guest, the guest's VRAM size needs to be configured to at least 128 MB.
