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.
Optimizing Windows 11 for lower RAM improves performance on budget PCs, which can influence consumer adoption and indirectly affect the digital advertising ecosystem by enabling more devices to run modern web applications and ads.

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 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.
Windows 11 adds Low Latency Profile for faster app launches
Microsoft has introduced a new "Low Latency Profile" in Windows 11 that speeds up application startup by briefly increasing CPU performance. The feature is delivered with the August update KB5121003 and alters CPU usage during app launches so the processor can run near full capacity for short bursts. Tests reported by Windows Latest show meaningful reductions in load times for Web-based apps (for example, the Weather app loading time fell from about eight seconds to four). The update is rolling out in waves to users.
