Quite an unstable operating system. Crashes basically every time you run it, even after a clean installation, especially when you're busy using Microsoft Word or such programs. Frequently presents a blue screen of death
for no reason whatsoever.
"Windows 98 crashed again."
The only way that you could make this OS run for any period of time is by not running it. Or just run the whole thing from its 16-bit (but really 2-bit) command line, DOS.
My dog could write better operating systems than Windows 98 by urinating on a keyboard.
"Critical errors are the result of you asshats deleting system files" <--- But umm it crashed on clean Install. =/
