Windows 11 Performance Optimization Feature Revealed in Leak, Associated with Copilot Branding

Microsoft is currently exploring a groundbreaking feature known as “Windows Health and Optimized Experiences, ” which has recently emerged in Windows 11 Build 27863 (Canary).Notably, the term “Copilot” is associated with this feature, indicating that Microsoft may envision using this brand for the health-focused attribute of Windows, although it doesn’t seem to integrate with the AI assistant’s chat functionality.

Initially discovered by developer Albacore, the “Windows Health and Optimized Experiences” feature operates on a minimalist Lua runtime embedded in the whesvc_assets.dll file. For those unfamiliar, Lua is a lightweight programming language known for its speed and minimal memory usage, making it an intriguing choice for optimizing system processes.

The above screenshot illustrates that, upon activation, the service invokes windialog.exe, supplying it with a Lua script (referred to as ecp.v2.lua) that contains a JSON profile. Significantly, it features a reference to “ECP CoPilot, ” also known as Efficiency Copilot, hinting at a possible link to the Copilot app without explicitly engaging with the chat interface.

This brings forth the idea that Microsoft may promote the Windows 11 health feature under the Copilot branding. However, it remains to be seen whether this is a marketing strategy, a mere placeholder, or an error.

Within the script, the function disable_global_variables() secures the Lua environment, preventing any rogue code execution. The script constructs an opts table informed by environment variables, including:

WINDIAG_ECP_EVAL_SEC: Defines how frequently to sample data.
WINDIAG_ECP_TELEMETRY_FREQUENCY_MINUTES: Determines the timetable for uploading summary data.
WINDIAG_ECP_BATTERY_PCT_THRESHOLD: Specifies the battery percentage that triggers corresponding actions.

This indicates that the “Windows Health and Optimized Experiences” script monitors various metrics, including screen brightness, power mode, CPU load, and thermal conditions, to optimize battery health and overall performance.

Nonetheless, it is still uncertain whether Microsoft will make automatic adjustments to enhance system health or simply offer suggestions for manual changes. The potential recommendations could include alterations to PC settings, such as adjusting brightness or modifying the Windows “Power Mode” slider to minimize energy consumption.

As noted by developer Albacore, the use of “Copilot” in this context is likely a branding decision. The core function of the script appears to focus on monitoring battery state and making pertinent adjustments to maximize battery life, targeting aspects like brightness and power settings.

Understanding Windows Health and Optimized Experiences

In the coming weeks, Microsoft might formally announce the “Windows Health and Optimized Experiences” feature. However, from initial insights, it appears to be an unremarkable enhancement. Ultimately, it seems like a scripted tool designed to sample performance and battery metrics in real-time and provide recommendations for extending battery life.

Additionally, it looks like Microsoft may opt to collect telemetry data to fine-tune the algorithm, but this aspect is expected to be optional for users.

According to information extracted from Resources Hacker, it’s possible for Microsoft to gather up to sixty readings every second and relay compressed telemetry data back to its servers every fifteen minutes.

Frequently Asked Questions

1. What is the purpose of the Windows Health and Optimized Experiences feature?

The Windows Health and Optimized Experiences feature aims to monitor system performance and battery health through real-time metrics. It suggests modifications to settings such as screen brightness and power modes to prolong battery life.

2. How does Microsoft collect telemetry data with this feature?

Telemetry data is collected based on continuous performance readings from the device. This data helps Microsoft fine-tune the optimization algorithms, but participation in data collection is expected to be optional for users.

3. Is there a risk to user privacy with the telemetry data collection?

While Microsoft may collect telemetry data to improve the functionality of the feature, users have a choice to opt-in or out of this data collection, allowing them to maintain control over their privacy settings.
