alt Hacker NewsFrom the user perspective, Windows and Office certainly crashed more frequently back then. I don't mean that as a criticism of the Microsoft developers at the time: they did some great work within severe constraints. But overall the product quality is far better now.
I wouldn't take that as criticism; you are 100% correct. But that instability was a direct result of the issues I mentioned above: the ring transition protection/implementation was absolutely horrible; 3rd-party developers would discover a useful function in NTDLL and start using it in unintended ways, etc.
Do you remember the CSRSS Backspace Bug? [0]
A simple: printf("hung up\t\t\b\b\b\b\b\b"); from ring-3 would result in a BSOD. That was a pretty major embarrassment.
After retiring, I started volunteering my time to mentor CS students at two local universities. I work with juniors and seniors who have no idea what "heap memory" is because, for the most part, they don't need to know. For many developers, the web browser is the "operating system".
I absolutely love using Python because I don't have to worry about the details that were major issues back in the 90s. But, at the same time, when I run into an issue, I fully understand what the operating system is doing and can still debug it down to assembly if need be.
