List of Free Operating Systems: Download Now!

Posted on 12 January 2009

There are an increasing number of equipment manufacturers and technology groups that provide operating systems (OS) for free personal and commercial use without any cost or fee. You are sometimes even free to use them, change their source code and redistribute them as well.

Like Anything that comes for free, do not expect fancy printed manuals and CD-ROMs and technical support. Yet you can count on the community that uses these OS to provide you support through chat rooms and forums and mailing lists.

You will also note that the size of these OS range from 1 to 10 GB so if you don’t have decent broadband connection, paying for a DVD/CD-ROM might seem reasonable. Also if you are not that techie, some of these companies offer helpdesk and support contracts, which can be bought at a reasonable price.


FreeDOS aims to be a complete, free, 100% MS-DOS compatible operating system (mostly achieved except Windows compatibility – Windows standard-mode works on FreeDOS, but 386-mode / WfW 3.11 does not.)


These days, there are three main uses for FreeDOS:

  1. Running classic DOS games
  2. Running business software that only supports DOS
  3. Supporting embedded DOS systems, such as a computerized cash register or till

FreeDOS should run on any standard PC, but if you are new to DOS, we recommend you use a PC emulator to install and boot FreeDOS. You can find PC emulators for all computer platforms (Windows, Linux, Mac.) You can even run FreeDOS using a PC emulator written in Java, right in your web browser!

RxDOS is a fast MS-DOS clone that supports very large disk drives, FAT32 volumes, and Windows 95/98 Long Filenames. its source code is also available free at sourceforge.

React OS

ReactOS is a free, modern operating system based on the design of Windows® XP/2003. Written completely from scratch, it aims to follow the Windows® architecture designed by Microsoft from the hardware level right through to the application level. This is not a Linux based system, and shares none of the unix architecture.

ReactOS 0.3.3ReactOS had its origins in an older project known as FreeWin95. FreeWin95 aimed at being binary compatible with Microsoft® Windows® 95. It was founded by Yannick Majoros around 1996. But the development never took off substantially due to endless talks on design and thoughts of following the NT architecture.

The main goal of the ReactOS project is to provide an operating system which is binary compatible with Windows. Adobe Photoshop 3This will allow your Windows applications and drivers to run 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 remove Windows® and install ReactOS without the end user noticing the change.Please bear in mind that ReactOS 0.3.7 is still in alpha stage, meaning it is not feature-complete and is not recommended for everyday use.

DarwinDawrwin Apple

Darwin is the UNIX technology-based foundation of Mac OS X. Darwin integrates several technologies. Among the most important aredarwin screenshot 4.4BSD-based operating-system services (built on the Mach 3.0 microkernel), the I/O Kit, networking facilities, and support for multiple integrated file systems. Developers can use Darwin to port UNIX/Linux applications and create kernel extensions.

In addition to being part of Mac OS X, Darwin is a standalone, BSD-based operating system. (BSD, short for Berkeley Software Distribution, is a family of UNIX variants descended from Berkeley’s version of UNIX.)Darwin is also occasionally used to refer to the Darwin Streaming Server, also known as the QuickTime Streaming Server (QTSS).

  20. Spuffler says:

    Ubuntu, Mandriva, Debian, Slackware, Knoppix, and Fedora are all just customizations of the same GNU/Linux OS. While I see the intention of this post as offering differences, users should be aware that underneath the different appearing window managers (and desktop managers), the same GNU/Linux software is at work.

Besides Ubuntu SUCKS because the 5.10 version crash several times on me, and to tell you all this MAC and Windows are the best operating systems got it? (Linux, ReactOS, and Wolvix are also okay.)

  31. Microsoft is no stranger to having companions galore in the telephone business, however its lineup of manufacturers for the upcoming, surprisingly promising Windows Cellphone 7 launch isn’t any much less impressive. After loads of rumoring, Microsoft has confirmed that Dell and HTC can be making Home windows Telephone 7 phones, in addition to ASUS, LG, and Samsung who had already been confirmed. All of those corporations should have their stamp on hardware by the top of the yr, with the launch of the OS nonetheless vaguely slated for the “holidays” We have no doubt that every one 5 producers can build some compelling, sexy hardware, but we’re significantly enthused to see Dell actually moving into the sport after the impressive Streak and that drool worthy leak a short time back. read more at fans group.

    I use FreeDOS to run some of the games that were favorites of mine throughout my youth. As silly as it sounds, it can be quite enjoyable to relive some of those old games. Although I am not doing anything too fancy, FreeDOS seems pretty stable.

    where can i got free cd of operating system various….send me link on

  45. disgruntled says:

    Its bit bad set of choices really.
    Either use a crap bloated insecure system from ms which drivers can usually be obtained for or use a decent OS without neccesary drivers being available for stuff like printers and modems for example. OR use one of these smart phones which drop to bits all the time and are sold by unscrupulous vendors eg crap phone hare house, phones for poo, the stink, etc. And when youve finally got on the net its becoming more and more difficult to find what you want due to how search engines do there listing, even meta search ones and of course you have to select a decent browser which will take a good ad blocker extension or see your download/usage limit reached before your very eyes

  46. This is a great list, I was not aware of two of these operating systems. I will be sure to download the operating systems I do not yet own and quintruple boot my pentium 4. How is React OS with server software does anybody know?
