If you're looking for Windows 7 software to install on your existing desktop or you are building a computer and need an operating system that you can add to it, eBay offers multiple options. When it comes to Windows 7 full retail, you have a lot of choices on eBay. Here is what you need to know to help you purchase your software.
How does the full retail differ from the OEM version?The original equipment manufacturer (OEM) version is intended for system builders and is usually sold with new computers. This version can be installed on only one device, while the full retail version allows installation on more than one computer. The full retail version may be installed on systems that are sold as used or refurbished.
Which operating systems are available in the full retail version?Windows 7 Home Premium, Windows 7 Professional, and Windows 7 Ultimate are all available in the full retail version. All three systems are available in 32-bit, and 64-bit formats and the following list summarizes their features:
- Windows 7 Home Premium: This includes support for Windows Media Center, DirectX, and premium games. It has multi-language support, and Shake and Peek features allow more efficient use of open windows and programs. It also supports home group for wireless connection to network devices.
- Windows 7 Professional: This includes Windows Explorer, offers support for Aero and DirectX, and allows connection of computers and printers to a domain for convenient networking and file exchange.
- Windows 7 Ultimate: This combines features of Home Premium and Professional editions, and it allows connection to home networks for convenient resource sharing.
The terms 32 bit and 64 bit refer to a computer's memory architecture and describe the way in which a computer processes information. A 64-bit system can process information more efficiently than a 32-bit system. You may be able to run some 32-bit software on computers that have a 64-bit architecture, but you will likely notice a difference in performance. The following list summarizes the functioning or 32 bit and 64 bit across three key layers of architecture:
- Processor: A 64-bit processor supports 32-bit and 64-bit operating systems. A 32-bit processor supports 32-bit operating system and applications.
- Operating system: A 64-bit operating system can run only on a 64-bit processor and will support applications that are 64 bit and 32 bit. A 32-bit operating system can run on a 32-bit or a 64-bit processor and supports applications that are 32 bit.
- Application: A 64-bit application requires a 64-bit operating system, and a 32-bit application requires a 32-bit or a 64-bit operating system.
Both new and preowned Windows 7 full retail versions include Microsoft Office, Media Player, and Internet Explorer, and they offer full support for Wi-Fi, Ethernet, and Bluetooth technologies. Windows XP mode allows cross-compatibility with older software. Additional features may differ, depending on the version of the operating system that's installed.
