How do I clean registry in windows 11 after uninstalling apps?

For advanced users, you can write a PowerShell script that targets and cleans specific registry entries, such as unused keys from uninstalled software, leftover settings, etc. This is not typically recommended for beginners but can be effective in targeting specific areas of the registry.

$keyPath = "HKCU:\Software\Microsoft\Windows\CurrentVersion\Uninstall"
$keys = Get-ChildItem -Path $keyPath
foreach ($key in $keys) {
    Remove-Item -Path $key.PSPath -Recurse -Force
}

This script will clean windows 11 registry entries under the uninstall section for software that may no longer be installed
