Fix Game stuttering and Micro-Lags Caused by NPU/AI Features and “Recall / Copilot”

Situatie

Problem: On newer laptops or PCs (especially those equipped with NPUs or Copilot+ features), games or graphics-intensive applications experience brief frame hitches (micro-stuttering), even though GPU and CPU usage are nowhere near 100%

Cause: Background local indexing and contextual analysis services (AI Core Services / WebExperienceHost) continuously attempt to process screen frames or text in real time.

Solutie

Solution (Command Prompt / Registry):

Disable background AI telemetry and advanced indexing using a single command run with elevated privileges:

Press Win + S, type cmd, right-click Command Prompt, and select Run as administrator.
Execute the following command:

DOS

reg add “HKLM\SOFTWARE\Policies\Microsoft\Windows\Windows Copilot” /v TurnOffWindowsCopilot /t REG_DWORD /d 1 /f

Effect: Windows stops allocating system resources to background AI processing, eliminating sudden frame drops and input lag in games and rendering software.
