Awesome script Nick!

For things like Dark Mode, I found you might be able to change those with a .theme file instead, and then just point to a .theme file

Maybe this is something you guys want to add. You need to have WinGet installed or you can use Chocolatey with the script from here

$Programs = @(
    "Discord.Discord"
    "Git.Git"
    "Microsoft.AzureCLI"
    "Microsoft.DeploymentToolkit"
    "Microsoft.PowerToys"
    "Microsoft.VisualStudioCode"
    "Microsoft.WindowsTerminalPreview"
    "OpenJS.Nodejs"
    "RARLab.WinRAR"
)

$programs | ForEach-Object{winget install $_}

Quick thankyou for all of the above; which I am using bits of. Cheers

This is probably a dumb question, but does this work on Windows 11 (Pro)?
