Here we are talking about how to fix Windows 11 system using too much data. If you want a more aggressive cleanup of Windows components that may be using data in the background, there is a free, open-source PowerShell script called Win11Debloat.
What it does:
- Removes preinstalled apps
- Disables telemetry and diagnostic data collection
- Turns off Start menu ads and suggestions
- Removes Copilot button and widgets
How to fix Windows 11 system using too much data:
1. Open PowerShell or Terminal as Administrator
2. Run the following command (downloads and runs the script directly):
text
& ([scriptblock]:: Create((irm "https//win11debloat. raphi. re/")))
3. Select the changes you want to apply
The script creates a System Restore point before making changes, and most changes are reversible. I recommend running this only if you are comfortable with command-line tools.
