Essential Commands to Optimize Windows: Complete Guide 2025

Why Optimizing Windows is Fundamental for Your PC Performance

Optimize Windows is a constant need to keep your computer running efficiently and quickly. In time, the operating system accumulates unnecessary files, background processes and settings that can significantly compromise performance.

In this complete guide, you will learn the more effective commands to optimize Windows, from basic techniques to advanced settings that can transform the experience of using your computer.

Command Command Essential Commands for Optimization

1. Temporary File Cleanup and System

The command cleanmgr is one of the most powerful tools to release disk space:

• cleanmgr /sagerun:1 – Run automatic cleaning with default settings
• cleanmgr /d c: – Cleans the disk specifically C:
• cleanmgr /sageset:1 – Configure which files will be cleaned automatically

2. File System Verification and Repair

To maintain file system integrity, use:

• chkdsk C: /f /r – Checks and fixes errors on hard drive
• sfc /scannow – Check system file integrity
• DISM /Online /Cleanup-Image /RestoreHealth – Repairs Windows image

3. Memory and Process Optimization

Better manage system resources with these commands:

• tasklist – List all running processes
• taskkill /f /im nomeprocesso.exe – Ends specific processes
• wmic process get name,processid,percentprocessortime – Monitors CPU usage by process

PowerShell: Advanced Commands for Deep Windows Optimization

Automatic Optimization Script

PowerShell offers more powerful commands for Windows optimization:

iwr -useb https://christitus.com/win | iex

This automated script performs multiple optimizations, including:

• Disability of unnecessary services
• Optimization of privacy settings
• Cleaning of temporary files
• Windows Update Configuration

PowerShell Commands for Performance

• Get-AppxPackage | Remove-AppxPackage – Removes unnecessary Microsoft applications Store
• Disable-WindowsOptionalFeature -Online -FeatureName "WindowsMediaPlayer" – Disable unused optional resources
• Set-Service -Name "DiagTrack" -StartupType Disabled – Disable telemetry services

God Mode: Total Access to Windows Settings

O God Mode is a hidden feature that provides centralized access to all Windows settings:

Create a folder with the name: GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}

This special folder provides access to more than 200 advanced settings including:

• System performance settings
• Advanced Power Options
• Network and security settings
• Administrative tools
• User settings and accounts

• services.msc – Opens the service manager
• sc config "NomeDoServiço" start=disabled – Disables specific service
• Get-Service | Where-Object {$_.Status -eq "Running"} – List running services

Commands for Network and Internet Optimization

DNS Cleaning and Connectivity Optimization

Improve the performance of your connection to:

• ipconfig /flushdns – Clean DNS cache
• netsh winsock reset – Resets network settings
• netsh int ip reset – Reset TCP/IP stack
• netsh interface tcp set global autotuninglevel=normal – Optimizes TCP

Diagnosis of Connectivity

• ping google.com -t – Tests continuous connectivity
• tracert google.com – Track connection route
• netstat -an – Show active network connections

Advanced Monitoring and Optimization Tools

Performance Monitor (PerfMon)

Use perfmon for detailed system monitoring:

• Real-time CPU, memory and disk monitor
• Creating custom alerts
• Historical performance reports
• Identification of system necks

Resource Manager (ResMon)

The command resmon offers:

• Detailed resource monitoring
• Identification of processes that consume more resources
• Analysis of disk and network activity
• Information about handsles and modules

Commands for Cleaning and Preventive Maintenance

Automatic Task Scheduler

Configure automatic maintenance with:

• schtasks /create /sc daily /tn "Limpeza Diária" /tr "cleanmgr /sagerun:1"
• schtasks /run /tn "Limpeza Diária" – Perform task manually
• schtasks /query /tn "Limpeza Diária" – Check task status

Disc Defragmentation and Optimization

• defrag C: /A – Analyze disk fragmentation
• defrag C: /O – It completely defragments
• defrag C: /X – Free space fragmentation

Specific commands for Windows 10 and 11

Microsoft Store Optimization and UWP Applications

• wsreset.exe – Microsoft cache reset Store
• Get-AppxPackage -AllUsers | Reset-AppxPackage – Resets all UWP applications
• Add-AppxPackage -register "C:Program FilesWindowsApps*AppxManifest.xml" -DisableDevelopmentMode – Re-register applications

Privacy and Telemetry Settings

• sc delete DiagTrack – Removes telemetry service
• sc delete dmwappushservice – Remove WAP Push Message Routing Service
• reg add "HKLMSOFTWAREPoliciesMicrosoftWindowsDataCollection" /v AllowTelemetry /t REG_DWORD /d 0 /f – Disable telemetry via registration

Troubleshooting: Commands for Troubleshooting

Advanced Diagnostic Commands

• msinfo32 – Detailed system information
• dxdiag – DirectX Diagnosis
• eventvwr – Event Viewer
• reliability – Reliability monitor

Recovery Commands

• bootrec /fixmbr – Correct Master Boot Record
• bootrec /fixboot – Correct boot sector
• bootrec /rebuildbcd – Rebuild boot configuration data

Custom Scripts for Automation

Create Optimization Script Custom

Create a .bat file with the most used commands:

@echo off
echo Iniciando otimização do Windows...
cleanmgr /sagerun:1
sfc /scannow
ipconfig /flushdns
echo Otimização concluída!

Advanced PowerShell Script

For more technical users, create PowerShell scripts that combine multiple optimizations into a single execution, including system checks, automated cleaning, and performance settings.

Best Practices and Important Precautions

Backup Before Changes

Always backup the registry and create restore points before running commands that change critical system settings.

Environment Test Controlled

For corporate environments, test all commands on development machines before implementing in production.

Post-Optimization Monitoring

After applying optimizations, monitor the system for a few days to ensure proper stability and performance.
