01.What is Bloatware and why remove it?

"Bloatware" (Swollen Software) are apps that come pre-installed in Windows 11 that you never asked for and probably will never use. Examples: Disney+, Clipchamp, News, Weather, OneDrive, and the Cortana assistant.

They don't just take up disk space; they run background processes to fetch notifications and updates, consuming CPU and RAM that should go toward your games or work.

🚀 Safe 1-Click Debloat

Messing with PowerShell can be scary. Voltris Optimizer has a "Smart Debloat" module that identifies what is safe to remove and what is vital for the system, cleaning your PC without breaking the Store or Windows Update.

Recommended Optimization

Don't do it Manually.

02.Method 1: PowerShell (Manual and Safe)

We will use the Remove-AppxPackage command to uninstall apps that don't have an "Uninstall" button in settings.

  1. Right-click the Start Button > Terminal (Admin) or PowerShell (Admin).
  2. To remove Xbox Game Bar (if you don't use it):
    Get-AppxPackage Microsoft.XboxGamingOverlay | Remove-AppxPackage
  3. To remove Cortana:
    Get-AppxPackage -allusers Microsoft.549981C3F5F10 | Remove-AppxPackage
  4. To remove Phone Link:
    Get-AppxPackage Microsoft.YourPhone | Remove-AppxPackage
  5. To remove Maps:
    Get-AppxPackage *windowsmaps* | Remove-AppxPackage

03.Method 2: Automated Scripts (WinUtil)

The community has created amazing tools. Chris Titus Tech's (CTT) script is the gold standard in 2026.

  • Open PowerShell as Admin.
  • Type: iwr -useb https://christitus.com/win | iex
  • A graphical window will open. Go to the "Tweaks" tab.
  • Select "Desktop" (if it's a desktop PC) or "Laptop".
  • Click "Run Tweaks".
  • This will disable Telemetry, Wi-Fi Sense, Activity History, and remove temporary bloatware.

A1.Forcefully Removing OneDrive

⚠️ Beware of your Files

Before removing OneDrive, make sure your Desktop and Documents folders are saved locally. OneDrive often "hijacks" these folders.

In CMD (Command Prompt) as Admin, execute:

taskkill /f /im OneDrive.exe

%SystemRoot%\System32\OneDriveSetup.exe /uninstall

%SystemRoot%\SysWOW64\OneDriveSetup.exe /uninstall

Consequences of Debloating

Benefits

Windows Search may become limited (no web results). Widgets may stop working. The Microsoft Store still works, but automatic updates may be paused.

Frequently Asked Questions

Common questions answered by Voltris technical team

Q1.Can I reinstall the Calculator if I accidentally delete it?

Yes. Open the Microsoft Store, search for 'Windows Calculator', and install it. All native apps are in the store.

Q2.Does debloating increase FPS?

Directly, very little (1-3 FPS). Indirectly, it prevents FPS drops (Stuttering) caused by background processes that wake up the CPU during gameplay. On PCs with 8GB of RAM or less, the difference is massive.

Q3.Does this break Windows Update?

The methods listed here (PowerShell) DO NOT break Windows Update. Aggressive 'Windows Lite' scripts (modified ISOs) do, but this guide focuses on keeping the original system stable.
