Windows 98 Disk Defrag Simulator

Indeed. This 3-hour long "ASMR" version including hard drive sounds is one of the better ones [1]. It seems oddly satisfying to watch a couple of single sectors getting written into the holes and reshuffled, after which an enormous block of sectors gets dark blue at once. All while listening to the hard drive sounds that are in symphony with the graphics.

When defragging my own computer in the past, I could look at this for an embarrassingly long time, but I've also just watched this YouTube video up to timestamp 00:08:50.

It's nitpicky, but I'm the same way. In this version there's too much padding above/below the ? and X buttons in the title bar.

If I ever win the lottery I'm going to live out my days building a GUI framework that looks like Windows 95, including unit tests that make sure the widget rendering is pixel-perfect.

It's difficult to disable font anti-aliasing in the browser.

One factor might be screen size.

In 1998 it was typical to have 1024x768 monitors at about 72 DPI. Shortly afterwards, the whole world switched to a 96 DPI standard, at higher resolutions.

Different drives which you can choose trough the settings button, have different sounds. Try the E drive.
