KeePassXC is a in place alternative for keepass ( they are interchangable )

Sandboxie-Plus only helps with "specific" malware. I recommend you the optional windows sandbox feature. ( Optional Features => "Sandbox" )

For those who dont want to get probably spied on. As Vivaldi is chromium and that is controlled from google. Go use Firefox, or rather Librefox its a real alternative to chromium. ( Its less creepier )

Codium as an de-microsofted Visual Studio Code alternative.

I absolutely couldn't be without SnagIt, especially the Editor for Screenshots makes my live so much easier.

I'll add AlomWare Toolbox to this list. Been using it for years to do almost anything on my PC that gets annoying/repetitive, like typing my email and moving my app windows to where I like. The clipboard history and "Map" are great features, too.
