Debloat Windows 11

Windows 11 comes with a host of pre-installed applications and background services that are often unnecessary. These programs, known as ‘bloatware’, slow down your system. Win11Debloat, a simple and effective PowerShell script that removes unwanted software, disables telemetry and optimises the interface in just a few clicks.

Windows 11 integrates many applications and services that most users never use. What's more, Microsoft collects data via telemetry, which can raise questions about privacy. Win11Debloat is a solution that allows you to :

  • Remove unnecessary applications installed by default.
  • Disable telemetry and data collection services.
  • Optimise the user interface by removing intrusive elements.
  • Make the system lighter and more responsive.
  • Save time by automating changes without manual intervention.

How do I use Win11Debloat ?

Using the script is relatively simple, even for those who are not computer experts. Here are the steps for running it safely :

1. Download the script

Go to the official Win11Debloat GitHub repository and download the PowerShell script.

2. Run PowerShell in administrator mode

Before running the script, open PowerShell in administrator mode by searching for ‘PowerShell’ in the Start menu, then clicking on ‘Run as administrator’.

3. Authorising script execution
