Installing Windows 7

System Requirements & Setup

Written in January 17, 2026

For context, Windows 7 is a popular Microsoft operating system released in 2009. It is known for its stability, simple interface, and improved performance compared to Windows Vista (2007).

It holds a special place in my head as it is my generation's nostalgia, especially for me. I used to play a lot of Plants Vs. Zombies and Purble Place on my grandpop's Acer Aspire One, to the point where I spent literal days without seeing the sun. The screensavers were the best too. Life was simpler then.

You can watch my YouTube video about a Windows 7 installation using VirtualBox.

Instructions

To run Windows 7 smoothly in VirtualBox, your virtual machine should be configured with a minimum of 1 GB of RAM for 32-bit or 2 GB for 64-bit, assigned at least 1 CPU core (though 2 is better for stability), and allocated 16 GB to 25 GB of storage space.
  1. Open VirtualBox and click "New" to create a new virtual machine.
  2. Name the VM (for example "Windows 7"), set Type to "Microsoft Windows", and select the appropriate Windows 7 version template (32-bit or 64-bit).
  3. Allocate at least 1 GB of RAM for 32-bit or 2 GB for 64-bit, as described in the summary above.
  4. Assign 1 to 2 CPU cores under Settings → System → Processor.
  5. Create a new VDI virtual hard disk, dynamically allocated, with a size between 16 GB and 25 GB.
  6. Open Settings → Storage and attach your Windows 7 ISO to the virtual optical drive.
  7. Optionally increase Video Memory and enable 3D Acceleration under Settings → Display for smoother visuals.
  8. Start the VM and press any key when prompted to boot from the DVD/ISO.
  9. Follow the installer to choose your language, accept the license, and create/format a partition using NTFS.
  10. Let the installation complete and reboot into the Windows 7 desktop.
  11. After the first login, eject the ISO and install VirtualBox Guest Additions to improve resolution, mouse integration, and shared clipboard.
