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
- 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

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}
- 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}
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 consolidationUsbCeip - 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
