I have a Dell laptop with Windows 7 hosting VirtualBox and one Windows XP VM.
I did install Oracle_VM_VirtualBox_Extension_Pack-4.3.6-91406, but I didn't get option to update the screen resolution over than 800x600.
I tried to update the video adapter, but there are no other option available.
(I tried the same Windows XP VM on VMware player and it gets the same host's screen resolution - much better).
Could someone help me, please.
Best regards,
