What is the most important program on your computer other than internet browser?

The most important program on my computer is the ...
Operating System!
The OS is the gateway that connects the hardware to the software? How else would I be able to run other programs if there was no central authority to manage all of them and make sure they don't do anything bad?
I can't do anything with out it, so it is very important.

Most likely it would have to be either my Anti Virus, or task manager

My programs that are useful to me are (in no particular order):
* F.lux
* Discord
* Microsoft Office programs
* iTunes/Spotify

The most important program on my system is vmware workstation 14, below that since I am not mentioning web browsers. VLC player, Notpad ++, Discord, and qtox. Also like steam and PIA.

Probably Steam ^^

But also teamspeak, i dont know really

Clearly it's photoshop that I use the most after my internet browser :money:

NotePad++, Wire care 365, Steam, File Zilla --- are the key things I need.

telegram, adobe series are important for me after thet Microsoft office.

Discord and steam for sure nothing is more important than those 2

My most important program is Steam since all of my games are on there and i think if i say steam my games are included in that
