Microsoft Explains Why Windows 11 Will Use Less RAM

⚡ The gist in 5 seconds - Microsoft has officially made memory optimization for Windows 11 a priority for PCs with 8 GB of RAM and above. - The reason is rising DRAM prices, which Windows chief Pavan Davuluri acknowledged. - Some optimizations are already available in Insider builds; the real impact still needs to be tested on low-end configurations. ### 🔍 What was found On the Inside Windows podcast, a Surface Pro owner complained that he had to disable local AI services to run a model. In response, Davuluri explained that memory is now a key focus due to rising computer costs, and talked about work on improving memory utilization. This happened in May, and on July 31 Microsoft officially added "Memory optimization for 8GB and above" to the list of new Windows development priorities. The optimization touches the memory manager, memory compression, and the WinUI 3 and WebView2 frameworks. Marcus Ash from the design team clarified that Widgets and File Explorer take a scenario-based approach: looking for ways to improve memory efficiency for specific scenarios. Davuluri added that memory should only be consumed when a feature is in use, and the base system will become lighter. Microsoft is also modernizing WinUI 3, starting with the Run and File Explorer dialogs, and in July announced tuning WinUI 3 and WebView2 for lower memory usage, including a new allocator. Most of this work remains in Insider builds for now. ### 💡 Why it matters Rising DRAM prices due to the AI boom have led OEMs to release laptops with 8 GB of RAM again — Lenovo, for example — while Microsoft sells a Surface Laptop with 8 GB for $1,299. If Windows 11 uses memory more efficiently, owners of such devices will be able to work more comfortably and run local AI models without disabling system features. It also eases the pressure on users who were previously simply told to buy more RAM. ### 🧩 Context Windows 11 long required a minimum of 4 GB, but Microsoft raised the bar to 16 GB for Copilot+ PCs and actively added web-based interfaces, which increased memory consumption. Now the situation has changed: memory manufacturers have shifted capacity to HBM and server DRAM for AI data centers, causing contract prices for regular DRAM to rise 10–15% quarter over quarter in Q4 2026, according to TrendForce. Microsoft itself is investing billions in AI infrastructure (an expected $80 billion in fiscal 2025), so it has to optimize Windows to keep the system from choking on affordable configurations. The irony is that the company helped accelerate the rise in memory prices, and is now making its OS lighter.
