i just made a VERY small operating system measuring only 2,5 kb for example, windows 10 measures about 16 gb, so 8 million times bigger than that os.  I'm not kidding.

among the features, it can:

-make you write stuff, like in windows

-make you draw stuff, like in windows

-it has a password (0000 by default) like in windows

-it is WAYYYY faster that windows

-it shuts down instantaneously

you can access help by typing 'h' on the console
