AtlasOS includes debloat tweaks that remove bloatware, disable unnecessary scheduled tasks, and optimize storage settings. These tweaks are defined in YAML configuration files located in Configuration/tweaks/debloat/.

Overview

Debloat tweaks in AtlasOS focus on:
  • Removing unnecessary Windows features
  • Disabling resource-consuming scheduled tasks
  • Optimizing storage management
  • Hiding unused system pages
  • Reducing system overhead

Scheduled Task Management

Disable Scheduled Tasks

This tweak disables several scheduled tasks that:
  • Update compatibility databases
  • Collect diagnostic data
  • Report telemetry to CEIP
  • Send usage data for A/B testing
  • Perform unnecessary background operations
The ignoreErrors: true flag ensures the tweak continues even if a task doesn’t exist on certain Windows versions.

Storage Management

Configure Storage Sense

Storage Sense configuration:
  • Enables automatic temporary file cleanup
  • Runs monthly to maintain storage
  • Preserves Downloads folder contents
  • Keeps Recycle Bin intact
  • Disables OneDrive cleanup (as OneDrive is removed)
  • Enables silent disk cleanup task

Disable Reserved Storage

Disables Windows 10/11 reserved storage feature that sets aside 7GB+ of disk space for updates. This frees up storage space on systems with limited disk capacity.

Content Delivery Configuration

Configure Content Delivery

Disables Windows content delivery features including:
  • Suggested apps in Start Menu
  • Tips and recommendations
  • App suggestions in Settings
  • Pre-installed promotional apps
  • Automatic app installation
This reduces bloatware and unwanted app installations.

Interface Cleanup

Hide Unused Security Pages

Hides unused Windows Security pages from the security center interface, simplifying the UI by removing features that are disabled or not applicable in AtlasOS.

The following scheduled tasks are disabled:

Application Experience

  • PcaPatchDbTask - Program Compatibility Assistant database updates

UCPD

  • UCPD velocity - Universal Control Panel Diagnostics

YAML Structure

Debloat tweaks use several action types:

Impact on System

Debloat tweaks provide:
  • Reduced startup time
  • Lower idle CPU usage
  • Less disk activity
  • More available storage space
  • Cleaner user interface
  • Fewer background processes
  • Improved system responsiveness

Safety Considerations

  • All tweaks are reversible
  • Tasks use ignoreErrors: true for version compatibility
  • Critical system tasks are not disabled
  • Storage Sense preserves user data (Downloads, Recycle Bin)
  • Reserved storage can be re-enabled if needed for major updates
