If you cannot run PowerShell script in Windows 11/10 and see message Cannot be loaded because running scripts is disabled on this system, see this post.

Running PowerShell with elevated permissions and enabling script execution will ensure that UWScript.ps1 can apply the necessary system changes. You can find it here on its official GitHub repository.
