Debloat Tweaks - AtlasOS

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

---
title: Disable Scheduled Tasks
description: Disables scheduled tasks to prevent automatic tasks from running at startup, consuming resources and collecting user data
actions:
  # Updates compatibility database
  - !scheduledTask: {path: '\Microsoft\Windows\Application Experience\PcaPatchDbTask', operation: disable, ignoreErrors: true}
  
  # Data collection
  - !scheduledTask: {path: '\Microsoft\Windows\DiskDiagnostic\Microsoft-Windows-DiskDiagnosticDataCollector', operation: disable, ignoreErrors: true}
  
  # CEIP - safety measure
  - !scheduledTask: {path: '\Microsoft\Windows\Customer Experience Improvement Program\Consolidator', operation: disable, ignoreErrors: true}
  - !scheduledTask: {path: '\Microsoft\Windows\Customer Experience Improvement Program\UsbCeip', operation: disable, ignoreErrors: true}
  
  # A/B testing usage reports
  - !scheduledTask: {path: '\Microsoft\Windows\Flighting\FeatureConfig\UsageDataReporting', operation: disable, ignoreErrors: true}
  - !registryValue:
    path: 'HKLM\System\CurrentControlSet\Control\Ubpm'
    value: 'CriticalMaintenance_UsageDataReporting'
    operation: delete

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

---
title: Configure Storage Sense
description: Configures Storage Sense to automatically cleanup temporary files every month
actions:
  # Enable Storage Sense
  - !registryValue: {path: 'HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\StorageSense\Parameters\StoragePolicy', value: '01', type: REG_DWORD, data: '1'}
  # Run Storage Sense
  - !registryValue: {path: 'HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\StorageSense\Parameters\StoragePolicy', value: '1024', type: REG_DWORD, data: '1'}
  # Run Storage Sense every month
  - !registryValue: {path: 'HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\StorageSense\Parameters\StoragePolicy', value: '2048', type: REG_DWORD, data: '30'}
  # Enable cleaning temporary files
  - !registryValue: {path: 'HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\StorageSense\Parameters\StoragePolicy', value: '04', type: REG_DWORD, data: '1'}
  # Disable the 'Downloads' from being cleared
  - !registryValue: {path: 'HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\StorageSense\Parameters\StoragePolicy', value: '32', type: REG_DWORD, data: '0'}
  # Disable OneDrive cleanup
  - !registryValue: {path: 'HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\StorageSense\Parameters\StoragePolicy', value: '02', type: REG_DWORD, data: '0'}
  # Disable Recycle Bin cleanup
  - !registryValue: {path: 'HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\StorageSense\Parameters\StoragePolicy', value: '08', type: REG_DWORD, data: '0'}
  # Enable cleaning temp files
  - !scheduledTask: {path: '\Microsoft\Windows\DiskCleanup\SilentCleanup', operation: enable}

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

---
title: Disable Reserved Storage
description: Disables reserved storage for Windows Updates to have more storage space
actions:
  - !run: {exe: 'DISM.exe', args: '/Online /Set-ReservedStorageState /State:Disabled', weight: 30, ignoreErrors: true}

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.

Debloat Tweaks Summary

Category	What’s Removed/Disabled	Benefit
Scheduled Tasks	Compatibility updates, diagnostics, CEIP, usage reporting	Reduced CPU/disk usage
Storage Sense	Configured for safe cleanup	Automatic maintenance
Reserved Storage	7GB+ update reserve	More usable storage
Content Delivery	Suggested apps, tips, ads	Cleaner experience
Security Pages	Unused security features	Simplified UI

Configuration Location

All debloat tweak YAML files are located in:

src/playbook/Configuration/tweaks/debloat/
├── config-content-delivery.yml
├── config-storage-sense.yml
├── disable-reserved-storage.yml
├── disable-scheduled-tasks.yml
└── hide-unused-security-pages.yml

Disabled Scheduled Tasks

The following scheduled tasks are disabled:

Application Experience

PcaPatchDbTask - Program Compatibility Assistant database updates

UCPD

UCPD velocity - Universal Control Panel Diagnostics

Diagnostics

Microsoft-Windows-DiskDiagnosticDataCollector - Disk diagnostic data collection

Customer Experience Improvement Program

Consolidator - CEIP data consolidation
UsbCeip - USB device telemetry

Feature Flighting

UsageDataReporting - A/B testing and feature rollout data

YAML Structure

Debloat tweaks use several action types:

---
title: Tweak Name
description: What is being debloated and why
actions:
  # Disable scheduled task
  - !scheduledTask:
    path: '\Path\To\Task'
    operation: disable
    ignoreErrors: true
  
  # Configure registry setting
  - !registryValue:
    path: 'HKEY\Path\To\Key'
    value: 'ValueName'
    data: '0'
    type: REG_DWORD
  
  # Run system command
  - !run:
    exe: 'DISM.exe'
    args: '/Online /Set-ReservedStorageState /State:Disabled'
    weight: 30
    ignoreErrors: true

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
