- why windows doesn't starts up/shuts down as quickly as a TV?

Because a TV is just a monitor...plus you don't know how long it takes to turn off the screen goes black, doesn't mean it is fully off. Not to mention a TV is not running complex software like a computer does. Comparing a TV to a computer is like comparing a single-cell organism (TV) to a dog (computer).

- why we have to restart windows after installation/uninstallation of some applications?

Because those developers of those applications decided you have to?

- why printer's manufacturer don't make universal ink cartridge ?

That is where they get the money?

- why most web pages are not written in justified fonts (the same for Onenote of Microsoft, why we can't justify lines) !

Cause the designers of those web pages didn't want to use justified fonts?

None of these things have to do with Windows. Or computers in general....

An HP executive once told me that they make more money with printer cartridges than with PCs or printers. It's that easy.
