Here are some free UI systems to run on your PC.
ReactOS
ReactOS is a free open source operating system based on the best design principles found in the Windows NT architecture (Windows versions such as Windows XP, Windows 7, Windows Server 2012 are built on Windows NT architecture). Written completely from scratch, ReactOS is not a Linux based system, and shares none of the UNIX architecture.
The main goal of the ReactOS project is to provide an operating system which is binary compatible with Windows. This will allow you to run Windows applications and drivers as they would on your Windows system. Additionally, the look and feel of the Windows operating system is used, such that people accustomed to the familiar user interface of Windows would find using ReactOS straightforward. The ultimate goal of ReactOS is to allow you to use it as alternative to Windows without the need to change software you are used to.

Free Windows
Free Windows is a Linux-based operating system, that's why we can ensure its stable functioning, reliable virus protection and absolutely free software. So our new operating system is more stable and protected than Microsoft Windows, but at the same time it is less expensive. As well as Microsoft Windows this new operating system permits you to work with texts, use your favorite browser for Internet-surfing (Opera, Mozilla Firefox, Google Chrome), listen to music, watch video films, communicate with ICQ or Skype, play computer games and so on. But you don't need to buy expensive software licenses, because all the free analogs of payware are already included in Free Windows and this is the main difference between Microsoft Windows and Free Windows. You pay for the installation disk with Free Windows only once and then you can install it on an infinite number of computers. And of course you can additionally install all the programs you want. We hope that it will be comfortable for you to use Free Windows not only at home but also in the office.

Ubuntu is great but for someone who is switching from Windows 7 to Linux or perhaps want to take a user-friendly distro for a spin, PinguyOS is probably where they’ll want to start. Pinguy OS is based on Ubuntu 10.10 Minimal CD but is built to be easier to use, with lots more applications and integrated extensions (like CoverGloobus, Gloobus Preview, GNOME Do, and Docky) to make the interface more familiar to the Windows user. It’s a great alternative to Windows 7, the switch will be seamless.
