Fuchas
One of the best OSes (as said by me)
Fuchas in a Nutshell
Fuchas is revolutionnary in that it uses drivers instead of component access and support UAC (with separate permissions!) ! It's the end of the era where the program needs to maintain integration with different components, the OS now does it! The driver library will try automatically choosing the best driver, but it can be configured by user. Meaning programs adapt to components with no effort (e.g. Computronics cards)
A feature of Fuchas is security. If you do not trust a program, you can control permissions. Each account can have its own set of permissions. Allow one to have free access on a specific drive? You can do that!. Security is useful for computers on big servers with competivity. Although remember that without disk encryption, data can be accessed simply by using another operating system. Fuchas doesn’t hide files starting with ".", it uses attributes, filesystem’s one if supported on unmanaged drives, or with a .dir file at file’s parent directory.
Fuchas is also fast at startup, around 2x faster than OpenOS down like memory usage. And graphical features are optional, so you can use command-line on your T1 computer, and a graphical interface on T3, all on the same OS! And since the UI is compatible with 40x16 and doesn't uses a lot of memory, you can use both on a T1 computer!
Extra Features
For example, the GUI interface of Fuchas (named "Concert") uses the newly added GPU buffers when available in a way that is transparent to programs and user.
Interfaces
Here are the interfaces included: Fushell (a command-line shell) and Concert.
For example here is Fushell (warn: old version [4 major releases ago], but still a little representative):

and Concert as of Fuchas 0.7:

Install It
OpenOS:
Just type the following:
pastebin run EbHYvEE8 MineOS:
Search for the application 'Fuchas Installer'. Install it, launch it, and press Install.
Fuchas:
You’re on Fuchas 
(Note that all comments about broken installation below are outdated, and installers has been fixed!)

Cell is a graphical file manager for OpenComputers that allows you to browse files and open them in other programs, such as the editor or simply running .lua files.

You can also customize what programs can be used to open files through the programs.cfg file.
Tutorials:
Browsing files/directories Select files/directories by clicking on them in the panel on the right side of the screen If a directory contains a large amount of files or sub-directories, use the arrow buttons to scroll through pages To go up a sub-directory, click the up arrow To change directory to a sub-directory, select the sub-directory, and click on "Open..." in the options panel (bottom left) Using programs Select file/directory Select an option from the options panel (Run, Edit, Delete, etc.) Creating files/sub-directories Navigate to the directory where the file/sub-directory will be created Select "New File..."/"New Directory..." from the functions panel (top left) A prompt for the name will appear at the bottom of the screen. Enter the name for the file/directory Adding programs Open the programs.cfg file in the editor Add a new line for your program Warning: The syntax for the programs.cfg is very strict, and will not accept extra spaces/empty lines Enter this info separated by semicolons: Program name Text for the options menu File types (separated by commas, for all files put "all", for directories put "dir", for specific file types, put the extension including the ".") Command that runs the program ("?file?" is a wildcard for the selected file/directory) Additional options (separated by commas, does not require semicolon or comma at the end) "s" prevents Cell from erasing the screen before running the program For example, the line that add the editor is:  OpenOS Editor;Edit...;all;edit ?file?;  
Minimum Requirements:
Tier 2 Graphics Card Tier 2 Screen Tier 1 CPU 2x Tier 1 Memory Internet card only required for installation To install, run 
wget https://raw.githubusercontent.com/Elektron72/Cell/master/installer.lua installer.lua installer.lua At the prompt, enter the path where Cell should be installed.

This operating system is already one of the best OpenComputers operating systems I have seen. When will there be a text editor/file creation?

sence i saw igor Timofeev's mineos i was thinking if it was posible to get those static windows to move and infact there is:
 
welcome to the first showcase of the (really un-creative named) tacti OS:
 
as you can see it figtures moveable, sizeable, and interactive windows infact all programs running in the OS will be windowed!
useing my easy-to-use windowLib and windowed-program-api i'll happyly resive any feedback (download link avalable in the below posts)
(also its gonna happen anyway so come with those grammer currections poeple, i can take it)
 
i hope you guys will like my project
-thanks

No spoiler in the title. Just watch the video.
EDIT: Apparently someone's ComputerCraft fork is more findable on Google than the original OpenComputers repository, so here's the official source code: https://github.com/asiekierka/lunatic86
