Winamp 2.95 didn't need to connect to the internet, there is no background service, no application manager bloatware, no ads or music recommendations, and it loads in 1/10 of a second without any startup service or preloader. It really whipped the llama's ass.
Straight up win32 software back then just was simpler, and the programmers back then like Justin Frankel, Ludvig Strigeus, etc. cared about program efficiency. A single programmer could write several popular applications within the decade, and now every application needs a giant team. What happened?
