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

Visual Studio. Simply because of School. :please:
Need it to learn and pass my subjects.

Steam. It's always on and I never turn it off. Next to that is discord.

i think for me the programs are brackets (running my business), discord and skype, filezilla, xampp

I like this question.
Personally the most important apps in my laptop are : Quick Cliq, XYplorer, SublimeText and CentBrowse

Notpad ++, Visual Basic, Spotify, Taskmanager and Steam.

skype and browser, so i can brows nulledbb x) i can't leave this place at all.

Flux is the most important to me cuz ya boi over here doesn't want to ruin his eyes as he plays all night

Steam of course, or Notepad++/Filezilla/putty etc.

definitely discord or steam. gotta be able to chat with friends and play games.

I'd say either Skype/Discord or Microsoft Word. I run a homework service, so those two means of contact are equally important, along with the importance of Word.
