Problem: VirtualBox running on Windows 10 with a Windows 10 guest O/S doesn’t display the full screen.

I had this trouble and solved it using the “download guest additions” method.

While running Virtual Box with Windows 10 in it:

1) Open the Virtual Box Help, About (fig 01)

2) Get the version of Virtual Box (fig 02)

3) Go to the resource folder
4) Click on your version (in my case, 4.3.30) (fig 03)
5) Click and download the VBoxGuestAdditions_4.3.30.iso file (fig 04)
6) It will open exposing the directory inside the ISO.
7) Run the main installer: VBoxWindowsAdditions.exe
8) As it is installing it will change your resolution to the max for your host machine.
