If you are a VirtualBox user, it is possible that on certain occasions you have noticed that, after completing the installation of an operating system such as Windows, the desired performance or characteristics are not obtained for some reason. It usually happens with a multitude of operating systems, even though one of the most prominent with which it arises is in the installation of Windows, and One of the most obvious signs of this is that the screen is only seen in a frame rather than fitting in the window..
This can happen for several reasons, but the most common is that the operating system has not adapted correctly to the virtual machine and that, therefore, you do not have the necessary drivers for the operating system to work properly. Regardless, you shouldn't worry about it, since VirtualBox always includes the opportunity to install so-called “Guest Additions” to fix this problem.
So that you can install VirtualBox "Guest Additions" on a Windows virtual machine
As we already mentioned, the installation of the corresponding drivers is done with this service, so if you have problems, it is recommended that you try to install it since it is possible that they will be solved quickly. For this, with the virtual machine correctly started, you must go to the top and, on the menu Devices, select the last option: «Insert CD image of« Guest Additions «...» and wait for the machine to recognize it.
Then, you just have to run it with autoplay from the PC or from the notification itself, and install the drivers as if it were a standard program, allowing the installation of all the necessary files and permissions for this.
