You can't just run the PowerShell scripts on a regular Windows 10 installation as script execution is blocked by default on Windows 10. You can verify the code right on GitHub or after you have downloaded the files by loading them in any plain text editor. The very first thing you need to do to get started is to visit the project's GitHub page and hit the download button there to download the PowerShell scripts to the local system. Ideally, you run it right after installation of Windows 10. The program will remove certain apps, components and tasks, and make changes to the Windows Registry. Note: It is highly recommended that you create a system backup before you run Windows10Debloater.

Three different versions are offered that differ only in the level of control the executing user has over the process. Windows10Debloater may remove certain components and scheduled tasks.

Prime examples of these types of components are games like Candy Crush being advertised on Windows 10 Pro devices, and the Telemetry gathering components and scheduled tasks. There is certainly no shortage when it comes to programs that remove Windows 10 apps and other components that some users and administrators consider bloatware.
