Microsoft to Reduce Windows 11 Memory Usage
Microsoft announced plans to optimize Windows 11 to run more smoothly on systems with less RAM, with a particular focus on 8‑gigabyte devices. Windows lead Pavan Davuluri outlined a set of quality-focused priorities through the end of 2026 that include reducing memory consumption. The article cites Web (Chromium-based) as a likely contributor to high memory use and notes Microsoft is migrating parts of Windows to WinUI 3, which can lower per-app memory by sharing resources. Observers also point out that Copilot-Plus PCs already require 16 GB of RAM and speculate Microsoft may tighten practical RAM expectations for Windows 11 devices. Microsoft aims to deliver noticeable improvements for 8 GB and 16 GB systems by the end of 2026.

Windows 11 26H2 Cuts RAM Usage on 8GB PCs
Microsoft's Windows 11 26H2 update brings significant RAM optimizations, benefiting devices with 8GB of RAM. Independent testing by Windows Latest revealed that on an 8GB laptop, RAM usage dropped from over 5GB in version 25H2 to 3.3GB in 26H2. In a clean virtual machine installation, memory usage fell from 4.1GB to between 2.8 and 3.2GB. Microsoft attributes these improvements to enhanced memory management, allowing Windows to retain up to 2GB more active data in memory instead of offloading to slower storage, and to loading widgets only when opened, freeing up to 200MB. These changes are expected to improve performance and responsiveness on lower-spec PCs, though additional undisclosed optimizations may also contribute.
Windows 11 Weather App Slows PCs
Tests reported by Windows Latest and summarized by t3n show that the Windows 11 Weather app can consume unusually high system resources — up to about 1.2 GB of RAM and roughly 16.5% CPU even in idle on the tested system. The article attributes the resource usage to the app being implemented as a Web wrapper that loads an MSN Weather web view and spawns multiple subprocesses. By comparison, Apple’s Weather app on macOS used roughly 250 MB RAM idle and much lower CPU in the same tests. Microsoft previously updated the app (summer 2024) and has said it will replace some web apps with native versions, but it is unclear whether the Weather app will be migrated.
Microsoft trims Copilot AI integrations in Windows 11
Microsoft announced it will pull back some Copilot AI integrations in Windows 11 and focus AI functionality only where it provides clear value. Pavan Davuluri, head of Windows, said the company will reduce Copilot entry points in selected apps (including Photos, Notepad and the Snipping Tool) and concentrate on AI experiences deemed “genuinely useful.” The change responds to user trust and privacy concerns after mixed feedback to earlier AI additions and delays to features such as Windows Recall for Copilot+ PCs. Microsoft also introduced a Copilot behavior that occasionally prompts users to take breaks. Outside data cited in the report notes about 26% of devices still run Windows 10 (Statcounter) and a Pew Research poll found rising public concern about AI in mid‑2025.
