Microsoft Adds Automatic Performance Logging and Driver Analysis to Windows 11 Preview

A new Preview build stores performance logs locally until insiders submit feedback via Feedback Hub, requiring static driver analysis ahead of the 25H2 release.

Overview

  • The latest Windows 11 preview automatically detects performance hiccups and logs them to a temporary system folder for Feedback Hub reviews.
  • Logs remain on users’ PCs until they are voluntarily sent through a new “system sluggishness” section in the Feedback Hub.
  • Microsoft plans to use these richer diagnostics to pinpoint bottlenecks and accelerate performance and reliability fixes in the 25H2 update later this year.
  • Developers must now run static analysis checks on drivers to earn certification, aiming to catch code issues before drivers reach users.
  • The effort extends prior Windows 11 optimizations from 2023 and last year’s 24H2 release that improved taskbar, notifications, quick settings and startup app performance.
