Most people seem to like using VLC. To me, it's a player of last resort. It's useful because it seems like it can run anything so if all else fails I try VLC. But other than that, I really don't like using it.
When I was on Windows, I liked to use PotPlayer.
Foobar and Notepad++ are programs I've always installed.
Firefox is something I hate to have to use. Vivaldi is the better browser.
For image editing I liked Paint.NET.
Everything Search for search.
OBS for a screen recorder.
Audacity for audio editing.
FreeFileSync for syncing files.
HoneyView for an image viewer.
HWiNFO for hardware viewer
SteamMover is nice to have.
