In November 2026, Microsoft published the results of an internal Windows 11 optimization effort aimed at improving system responsiveness on computers with 8GB of RAM. According to the company, certain user operations are now executed up to 20% faster, and multitasking performance has improved by up to 40% compared to January 2026 builds of Windows 11. These changes stem from a redesigned memory management system, reduced background load, and lowered resource consumption by key ecosystem applications. ### Redesigned RAM Data Compression A key element of the update is a newly implemented data compression mechanism in RAM. Windows 11 can now retain up to 2GB of additional active information in memory that would have previously been offloaded to storage. The practical effect is that previously opened applications and browser tabs reload less frequently when returning to them, reducing waiting times and lowering disk wear. ### Prioritizing User Actions Over Background Processes Microsoft has changed the logic behind system resource allocation. When a user opens the Start menu, performs a search, or launches Settings, Snipping Tool, or File Explorer, the system temporarily elevates the priority of these operations while restricting background processes, including search indexing. This allows the interface to react to user actions more quickly even on memory-constrained machines. ### Faster Launch Times for Edge and Teams Specific ecosystem applications received targeted optimizations. The Edge browser now launches up to 33% faster, and Microsoft Teams cuts its startup time by up to 20% thanks to Efficiency Mode. In Edge, inactive tabs now enter sleep mode after 15 minutes by default instead of the previous two hours, further saving resources. ### Reduced Application Memory Consumption During multitasking tests, Microsoft managed to reduce the allocated memory footprint growth in Edge and the Microsoft 365 suite by up to 900MB. Word, PowerPoint, Excel, and Outlook account for approximately 360MB in savings, while widgets on PCs with 8GB of RAM or less now load only upon opening, freeing up roughly 200MB. The combined effect is a more stable experience when running multiple programs simultaneously. ### Testing Methodology and Limitations The company tested the results across more than 20,000 computers. In one test scenario, testers simultaneously opened 20 Edge tabs, a 4K video, heavy Word, PowerPoint, and Excel documents, as well as Outlook and File Explorer. On an 8GB RAM PC, completing this sequence took 40% less time compared to January builds. However, Microsoft emphasizes that resource-intensive tasks such as 3D modeling and professional video editing still require at least 16GB of RAM. ## Fact-Check & Sources - [Microsoft ускорила Windows 11 на ПК с 8 Гбайт памяти — многозадачность стала быстрее на 40 % window-new](https://3dnews.ru/1150813/microsoft-uskorila-windows-11-na-pk-s-8-gbayt-pamyati-mnogozadachnost-stala-bistree-na-40-) - Primary source: all figures (20%, 40%, 2GB, 33%, 20%, 900MB, 360MB, 200MB, 15 minutes, 20,000+ PCs) are taken from the text. - [Windows 11 26H2 втихаря ускорила работу ОС и сократила потребление оперативной памяти](https://3dnews.ru/1149487/windows-11-26h2-vtiharya-uskorila-rabotu-os-i-sokratila-potreblenie-operativnoy-pamyati) - Context: the 26H2 update (2026) genuinely accelerated the OS and reduced RAM consumption, consistent with the main article. ## FAQ ### Which computers see the most noticeable Windows 11 speedup? The optimization targets PCs with 8GB of RAM. For resource-heavy tasks like 3D modeling and professional video editing, Microsoft still recommends at least 16GB. ### How much faster has multitasking become? According to Microsoft's internal tests across more than 20,000 computers, multitasking performance has improved by up to 40%, and individual operations by up to 20% compared to January 2026 builds. ### What changed in the Edge browser? Edge can launch up to 33% faster, and inactive tabs now enter sleep mode by default after 15 minutes instead of the previous two hours.
