How to install Guest Additions for Windows 8.1 in VirtualBox - fixedByVonnie

How to install Guest Additions for Windows 8.1 in VirtualBox

Guest Additions is designed to marry common tasks between the Guest and Host operating systems so that your life as a VirtualBox user is easier.

Let’s say you’re running Windows 7 on the computer that has the VirtualBox installation and you want to install a Windows 8.1 VM in VirtualBox with Guest Additions.

The Windows 7 computer is called the Host machine because all your VMs are running inside it.  And the VMs are the Guest machines, in this case, Windows 8.1 is your Guest OS.

If this get’s confusing just imagine you were organizing a dinner party at home for your friends.  You are the dinner host and your friends are the guests because they are inside your home.  In the same way, your physical (real) PC is the Host and the virtual computers sitting around your dinner table are the Guests.

Benefits of Guest Additions

Guest Additions allows you to do a bunch of cool stuff.

For example, with Guest Additions, you no longer have to press funky key combinations to release the keyboard and mouse.

Without Guest Additions, you have to press the Host Key every time you want to liberate your mouse pointer from the VM.  I have to press Ctrli on my Windows 7 Host OS every time I want to free the mouse; Guest Additions fixes this annoying problem.

In addition, you get Shared Folders.  This is my favorite.  With Shared Folders you can easily transfer files from the Host OS to the Guest OS and vice versa.  The shared folders on the Host OS show up in the Network Locations of your Guest OS.

There are also a few other perks with Guest Additions such as having the Guest machines system time automatically synchronized with the Host.  You’ll also get the ability to share the clipboard so you can copy and paste stuff between computers.

Installing Guest Additions

You might be flummoxed if you open VirtualBox, click Devices and go to Install Guest Additions… 

That’s because there’s no visible indication that anything happened after you click Install Guest Additions.

Virtualbox Install Guest Additions

Here’s what you need to do:

Open up My Computer either by pressing the Windows Key + e or clicking the File Explorer icon in the taskbar.

Installing Guest Additions in VirtualBox under Windows 8.1 File Explorer

Double-click the VirtualBox Guest Additions drive and you’ll see all the files required to run Guest Additions.

Installing VirtualBox in Windows 8.1 File Explorer  2

If you’re running a 64bit version of Windows 8.1, choose VBoxWindowsAdditions-amd64; otherwise, choose the x86 (32bit) option.  If you’re not sure what version you’re running you can easily enter a command at the command prompt to find out.

I’m running Windows 8.1 32bit so I chose the x86 option

Once you click the file the Guest Additions installation wizard will show up.

    Sorry, I’m sort of a newbie, and I have a few questions. After looking around, most people say that android VM doesn’t have guest additions. (Random tidbit so you know what I am trying to get to work.)
    Anyways, I have downloaded the ISO, and have been trying to add it, but it won’t show the pop up box, or anything for that matter. I found your article, but it says to click on the guest additions that is shown on the my computer section. I don’t see that either. How do you set that up?

    • Are you trying to setup Guest Additions on an Android VM or Windows 8.1?

      • Michael Merrick

        I am trying to setup guest additions onto a Android VM from a Windows 8.1 physical machine. (My actual computer.) (As I said, very new to this.)

  • Umar Rabbani

    Worked!

    Actually, I didn’t know whether should I install VboxGuestAdditions.iso in the Host or in the Guest. This article solved the problem, Alhamdulillah 😀

    Thanks. 😀

  • Just installed 8.1 in virtualbox, and the video went all 4 color after installing the additions, had to boot into safe mode and uninstall the video driver and delete the drivers for the virtualbox video driver.
