Administrative User Creation and System Optimization

This script helps automate the setup of a new Windows environment by creating a new local administrator account, removing unwanted applications, adjusting UAC settings, and disabling unnecessary startup items and services.

Script Overview:

• Creates a new local user account with administrator permissions.
• Uninstalls specified built-in and Microsoft 365 applications.
• Adjusts User Account Control (UAC) settings for security.
• Disables unnecessary startup programs and services.

PowerShell Script:

# Define the username and password for the new account
$Username = "username"
$Password = "password"

# Create a new local user account with administrator permissions
try {
if (-not (Get-LocalUser -Name $Username -ErrorAction SilentlyContinue)) {
New-LocalUser -Name $Username -Password $Password -FullName "New User" -AccountNeverExpires -UserMayNotChangePassword $true
Add-LocalGroupMember -Group "Administrators" -Member $Username
Write-Host "User '$Username' created successfully with administrator permissions." -ForegroundColor Green
} else {
Write-Host "User '$Username' already exists. Skipping user creation." -ForegroundColor Yellow
}
} catch {
Write-Error "Failed to create user: $_"
}

# Uninstall unwanted built-in apps by package names
$AppsToRemove = @(
"Microsoft.SkypeApp",
"Microsoft.XboxApp",
"Microsoft.GetHelp",
"Microsoft.Office.Desktop",
"Microsoft.MicrosoftOfficeHub",
"Microsoft.OneDrive",
"Microsoft.Teams",

foreach ($App in $AppsToRemove) {
try {
$Package = Get-AppxPackage -Name $App -ErrorAction SilentlyContinue
if ($Package) {
Remove-AppxPackage -Package $Package.PackageFullName
Write-Host "${App} removed successfully." -ForegroundColor Green
} else {
Write-Host "${App} is not installed on this system." -ForegroundColor Yellow
