HOWTO: VirtualBox Guest Additions

From the official documentation it is not very clear, how to install the guest additions necessary to use shared folders. Here’s how it works:

VirtualBox Guest Additions is a .iso file, that can be downloaded from here (for version 4.6.3): The file in question isĀ  “VBoxGuestAdditions_4.6.3.iso”. Download it and burn it onto a CD. Boot your guest OS in VirtualBox and then insert the burned CD. The installer should start after the CD is recognized.

Tested with: Windows 7, Windows XP
