Why Windows 95 Crashed So Often In a fascinating YouTube video titled
"Why Windows 95 Crashed So Often," the creators delve into the tumultuous history of one of the most iconic operating systems of its time. The video explains not only why Windows 95, along with its successors like Windows 98 and ME, was notoriously unstable but also sheds light on the engineering choices that led to these issues.
The Foundation of Windows 95
Windows 95 was revolutionary upon its release, introducing features like the Start menu and USB support. However, it was plagued by instability, which the video attributes to several fundamental design flaws rooted in its architecture. At its core, Windows 95 was built on
MS-DOS, a system that was never intended for multitasking. The OS followed a cooperative multitasking model, relying on programs to voluntarily share CPU time, which often led to system crashes when one application misbehaved.
Shift to Preemptive Multitasking
The introduction of preemptive multitasking in Windows 95 aimed to improve stability by giving the operating system more control over how CPU time was allocated. Unfortunately, this upgrade mainly benefited newer 32-bit applications, leaving older 16-bit software vulnerable to conflicts. The poorly implemented multitasking, combined with memory management issues like
memory leaks, meant that as the number of running applications increased, so did the likelihood of a crash.
Legacy Code Complications
The video's analysis highlights the impact of legacy code on system performance. Many applications, especially those designed for MS-DOS, accessed hardware directly and could interfere with the operating system's stability. Studies showed that not only did this legacy code pose problems, but even newly written device drivers sometimes shared memory space with critical components of the operating system, leading to increased vulnerability.
Transition to Stability
The inconsistency of Windows 95 and its predecessors eventually led to the development of Windows NT, which introduced a more stable architecture designed to handle multitasking efficiently and securely. Windows NT laid the groundwork for modern Windows operating systems, culminating in Windows XP in 2001, which brought home users a more reliable experience without the baggage of DOS roots.
Conclusion
Despite its flaws, Windows 95 holds a special place in computing history, beloved by many who remember its quirks and challenges. For those feeling nostalgic, there's even a playful suggestion in the video to experience the past by mimicking the environment of Windows 95, complete with a cyan desktop background and some classic games. Overall, the video serves as both a trip down memory lane and a critical analysis of the technological advancements that shaped the Windows operating system we know today.
