Oracle VirtualBox is a desktop virtualization platform for users who need to run, manage, test, and isolate multiple operating systems on one Windows computer.
Oracle VirtualBox is a hosted hypervisor developed by Oracle Corporation for creating and running virtual machines on a physical computer. On Windows, it allows users to install additional operating systems inside isolated virtual environments without replacing the host operating system. This makes it useful for software testing, development, training, compatibility checks, laboratory environments, and situations where several operating systems must be available on one PC. VirtualBox can manage guest systems including Windows, Linux, BSD, OS/2, Solaris, Haiku, and other supported platforms, depending on the host hardware and guest requirements. Its graphical interface provides a practical way to create virtual machines, allocate resources, attach installation media, configure virtual hardware, and control each guest separately. The software is therefore suitable for both technical users and people with basic knowledge of operating-system installation who need repeatable virtual environments.
VirtualBox combines full virtualization with configurable networking and guest integration features. A virtual machine can be assigned processor, memory, storage, display, and network settings independently from the Windows host, allowing different environments to be created for separate tasks. Guest Additions are available for some guest operating systems and provide device drivers and supporting software that can improve integration and performance, particularly graphics behavior and automatic display resizing when the virtual-machine window changes size. The supplied Windows build is version 7.2.16 for x64 systems and is listed at 169.5 MB. Its provided requirements include Windows 10 or newer, 8 GB of RAM, 2 GB of storage, and no dedicated GPU requirement. VirtualBox is also available on macOS, Linux, and Solaris hosts, while recent releases additionally support Apple silicon ARM64 on supported macOS systems.

Common questions about Oracle VirtualBox.
Oracle VirtualBox is used to create and run virtual machines on a Windows computer. A virtual machine can contain another supported operating system and operate separately from the host installation. This is useful for software testing, learning operating systems, development, compatibility checks, and maintaining isolated environments for different tasks. Instead of dedicating a separate physical computer to every operating system, users can manage multiple guest environments from the same Windows host, subject to available hardware resources.
The supplied research lists support for guest virtual machines running Windows, Linux, BSD, OS/2, Solaris, Haiku, and OSx86, with limited macOS guest virtualization on Apple hardware. Actual compatibility depends on the VirtualBox release, host platform, processor architecture, and the guest operating system being installed. Users should therefore treat the list as broad platform support rather than a guarantee that every historical or current release of those systems will work identically.
Guest Additions are optional drivers and system applications installed inside supported guest operating systems. Their purpose is to improve integration between the virtual machine and the host computer. The supplied research specifically mentions graphics performance improvements and automatic guest display resizing when the VirtualBox window changes size. These additions can make a guest system more convenient to use than a basic installation that relies only on the default virtual hardware drivers included with the operating system.
The supplied information describes VirtualBox as free and open-source software and lists the base package under GPL-3.0-only licensing. It also states that the optional VirtualBox Extension Pack is proprietary software and is licensed separately. Because the base application and Extension Pack use different licensing terms, users should distinguish between them when evaluating permitted use. The core Windows installer supplied here refers to the VirtualBox base package rather than treating every optional component as covered by the same license.
The supplied metadata lists Windows 10 or newer, an x64 processor, 8 GB of RAM, and 2 GB of storage for Oracle VirtualBox 7.2.16. It also states that no dedicated graphics card is required. The Windows installer is listed at 169.5 MB. These figures describe the provided application requirements, but virtual machines themselves need additional memory, processor capacity, and storage according to the guest operating systems and workloads being run inside them.
CrystalDiskInfo is an open-source Windows storage monitoring utility that reads S.M.A.R.T. data from supported HDDs, SSDs, NVMe drives, USB devices, and some RAID configurations to report health, temperature, and technical status.
TechPowerUp GPU-Z is a lightweight Windows graphics information and monitoring utility used to identify GPUs, inspect clocks and memory, monitor sensors, validate hardware details, test PCIe configuration, and back up supported video BIOS files.
Everything is a lightweight Windows file search utility that rapidly indexes file and folder names, updates results in real time, and supports filters, regex, advanced queries, content search, and file management.
GitHub Desktop is an open-source graphical Git client for Windows that helps users clone repositories, review file changes, create commits, manage branches, sync with GitHub, and handle common version-control tasks without relying on terminal commands.
