A detailed experiment conducted by YouTuber TrigrZolt revealed surprising data about the performance of different versions of the Microsoft operating system on older hardware. In a direct comparison involving six generations of the Windows, from XP to 11, the most recent system showed the slowest performance in most of the tasks evaluated. The test was carried out on identical Lenovo ThinkPad X220 notebooks, equipped with second generation Intel Core i5 processors, 8 GB of RAM and mechanical hard drives, a common configuration in equipment from a decade ago.
The analysis covered several crucial metrics, such as boot time, RAM consumption at rest, disk space usage, and speed in performing practical tasks such as opening applications and rendering media files. Enquanto o Windows 11 proved to be the most resource-demanding, Windows 8.1 emerged as the unexpected champion, presenting a remarkable balance between speed, efficiency and a relatively modern interface. The results raise a debate about software optimization and the growing demand for robust hardware with each new generation of operating system.
Although Windows 11 does not have official support for the hardware used in the test, the comparison serves as a clear demonstration of the impact that new features and security improvements have on older machines. Especialistas point out that the architecture of modern systems is designed to take advantage of technologies such as SSDs and multiple processing cores, making the experience on traditional hard drives significantly slower. The video highlights the evolution of the Windows over the years, showing a clear trade-off between lightness and advanced features.
Benchmark configuration details
To guarantee the impartiality and accuracy of the results, youtuber TrigrZolt used a rigorous methodology, using six perfectly identical Lenovo ThinkPad X220 notebooks. Lançado in 2011, this model was chosen because it represented an era when mechanical hard drives were still the standard and processors like the Intel Core i5-2520M were considered high performance. Cada machine received a clean install of a different version of the system: Windows XP, Vista, 7, 8.1, 10 and 11, all updated to the latest officially supported version.
This approach allowed us to isolate the software variable, making performance differences directly attributable to the characteristics of each operating system. The absence of an SSD (Solid State Drive) was a determining factor, as newer systems, especially the Windows 11, are highly optimized for the read and write speed of these drives. On a conventional hard drive, operations that would be instantaneous on a modern PC become noticeably slower, exposing bottlenecks in file management and starting background services.
Initialization and resource consumption
One of the first performance indicators analyzed was boot time. Neste question, Windows 8.1 stood out as the fastest, largely due to its “hybrid boot” functionality, which saves part of the system state when shutting down to speed up the next boot. In contrast, the Windows 11 recorded the longest time, showing a considerable delay before the desktop and taskbar became fully functional.
When it comes to resource consumption in idle state, older versions showed remarkable efficiency. The Windows XP led handily, using just 0.8 GB of RAM after boot. At the other extreme, the Windows 11 consumed between 3.3 GB and 3.7 GB of RAM, a direct consequence of the greater number of telemetry, security services and background processes that run constantly.
Disk space occupancy followed a similar pattern. A clean install of Windows XP took up just 18.9 GB, while Windows 11 required 37.3 GB. Essa substantial difference reflects the inclusion of more features, generic drivers and components that aim to ensure compatibility with a wide range of modern hardware, but which end up inflating the size of the operating system.
Analysis of performance in everyday tasks
In practical tests, which simulate daily computer use, the Windows 11 consistently came in at the bottom. Opening basic applications such as Explorador, Arquivos, Paint, and
Tasks that are more processor and disk intensive, such as exporting an audio file in the Audacity software and rendering a short video, also confirmed this trend. The Windows 11 took the longest to complete both activities, highlighting how the lack of optimization for older hardware directly impacts productivity in heavier applications.
One of the most revealing tests was internet browsing, which consisted of opening as many tabs as possible in a browser before the system reached its memory limit and became unusable. Windows 8.1 surprised us again, supporting the opening of 252 tabs. In stark contrast, the Windows 11 only managed to open 49 tabs before experiencing extreme slowdown.
Interestingly, battery life was the only aspect in which the differences were minimal between all the versions tested. Although XP had a slight advantage, lasting a few minutes longer, all operating systems had very similar power performance, suggesting that base hardware power management plays a more significant role than software optimizations in this specific scenario.
Results on synthetic benchmarks
To complement the practical tests, synthetic benchmark programs were used, such as CPU-Z, Cinebench and Geekbench, which measure the raw performance of the processor. Nestas evaluations, the Windows 11 generally positioned itself between the middle and the end of the table. The Windows 8.1 once again proved to be a strong competitor, winning in several single-core performance tests, an important metric for agility in everyday tasks.
The Windows XP, despite its age, managed to shine in specific disk speed tests, surpassing even newer versions in sequential read and write operations. On the other hand, the Windows 11 obtained one of its best results in the file copy test, coming in second place, just behind the Windows 10, which indicates specific optimizations in the I/O (input/output) subsystem that benefit this type of operation.
The unexpected highlight of Windows 8.1
The big surprise in the comparison was, without a doubt, the general performance of the Windows 8.1. Lançado in 2013, the system was widely criticized at the time for its radically different interface, focused on touch screens and the removal of the traditional Menu Iniciar. However, testing on hardware from its own era revealed that beneath the controversial interface lay an extremely optimized and efficient operating system. Ele combined the lightness of older systems with the ability to run modern software, presenting the best performance in startup, multitasking and memory management. Essa rediscovery highlights how public perception of software can be influenced by design decisions, obscuring important technical qualities. 8.1’s performance suggests that many of the low-level optimizations in 8.1 may have been deprecated in favor of new features and security layers in subsequent versions, such as Windows 10 and 11, resulting in a heavier system for legacy hardware.
Security versus performance on legacy systems
Despite the favorable results for older versions in terms of speed, it is essential to contextualize the security factor. Utilizar operating systems such as Windows XP, Vista, 7 or 8.1 on computers connected to the internet is extremely risky. Microsoft ended official support for these versions years ago, which means they no longer receive security updates, leaving users vulnerable to malware, ransomware and other digital threats that exploit known flaws.
Therefore, the test serves more as a technical curiosity and a study on the evolution of the software than as a practical recommendation. Para daily use, security should always be the priority, and in this regard, only the Windows 10 and Windows 11 offer the necessary protection with constant updates. Choosing an operating system must balance performance, functionality and, above all, the protection of user data. The ideal option for older hardware, if necessary, would be to look for lightweight Linux distributions, which combine low resource consumption with up-to-date support and security.
The crucial factor of modern hardware
It is crucial to emphasize that the scenario presented in the test changes completely when Windows 11 is run on modern and compatible hardware. On computers equipped with NVMe SSDs, latest generation processors and a generous amount of RAM, the Microsoft operating system offers a fluid, fast and responsive experience. Recursos such as DirectStorage, which accelerates game loading, and optimizations for processors with hybrid architectures (with performance and efficiency cores) can only be used on current machines.
The author of the video himself highlights that the objective of the experiment is not to discourage the use of Windows 11, but rather to illustrate the technological journey and the commitments inherent to software development. Cada new version adds layers of complexity, features and security measures that inevitably place greater demands on hardware. Para users who have recent equipment, migrating to Windows 11 remains the recommendation to gain access to the latest technologies and the most robust security support available in the Microsoft ecosystem.
