What is a computer "trick" that in the past was cool, but today is unimpressive and trivial?

1. In Windows 95 and 98 you could hack the boot screen and shutdown screen and override with whatever bitmap you wanted. Back when I bought my first computer in 2000 I replaced most of Microsoft branding with bitmaps of my own branding. Thus, it will boot, shutdown, show screensaver all with my own bitmaps. At least one girl in college was impressed that I wrote my own operating system ;-) 2. In DOS, you could overwrite the graphics memory in a very easy and straightforward way. Thus, you could put your content anywhere in the screen. We would write all sorts of silly worms for this and distribute it as a TSR [Terminate and Stay Resident Program] in a floppy disk. When our friend opens up this exe in the floppy it will overtake his screen and whatever he types would be replaced with something funny. Plenty of crazy stuff could be done through overwriting memory blocks. Mapping DOS Memory Allocation We would screw our windows installations so badly with many of these botched programs that at one point, I used to format & reinstall my OS every week.

Type on PDF: All You Need to Know

You need to know that all the software I used to mess up my system, was DOS based. Thus, we would have to change out the DOS drivers on the motherboard in order for programs to work. The only DOS programs that I could write, on DOS were the ones we wanted, and were in the .DOS files we wrote. This shows my DOS programming skills. The DOS kernel has a very simple, yet powerful, file system structure, that we would need to understand to actually create a DOS application. It is much later on that a couple of Microsoft developers would fix the DOS file system and make it more user-friendly. We were only able to do it for a portion of Windows' OS as we were doing this before. But the main problem with DOS had been solved years ago when I ported my own.
