I just returned back to the Windows world in Oct of 2017. Switching back to Windows for gaming, I’m listing below what Windows apps I have started to use as I replace each app from my Mac.
Notepad++ is a free (as in “free speech” and also as in “free beer”) source code editor and Notepad replacement that supports several languages. Running in the MS Windows environment, its use is governed by GPL License.
My preferred AntiVirus, very lightweight, never needs to update definitions because it’s cloud based. Does not affect game play.
