A YouTuber named TrigrZolt conducted tests comparing six versions of Windows (XP, Vista, 7, 8.1, 10, and 11) using six Lenovo ThinkPad X220 notebooks with Intel Core i5-2520M CPUs, 8GB of RAM, and 256GB HDDs, which do not meet the minimum requirements for Windows 11. Windows 11 ranked last in several metrics, including boot-up speed, memory consumption, and battery life. It was slower than all other versions in opening applications, particularly Paint and File Explorer. However, it ranked fourth in storage efficiency and performed reasonably well in one web-page loading test. The testing conditions, including outdated hardware and the choice of benchmarking applications, may have skewed the results against Windows 11. Users expressed concerns about Windows 11 being bloated and criticized its performance issues.
