PowerShell Bulk App Installer Script

What the script does

1. 1. Checks that it is running as Administrator and self-elevates if not
2. 2. Detects whether the selected package manager (WinGet or Chocolatey) is installed
3. 3. Loops through each selected app and installs it silently
4. 4. Catches errors per-app so one failure does not stop the rest
5. 5. Prints a summary table of successes and failures at the end

Script parameters

Three optional switch parameters control script behaviour:

.\install-ninichoco.ps1 -DryRun
.\install-ninichoco.ps1 -StopOnError -VerboseOutput

Admin self-elevation

The script checks [Security.Principal.WindowsIdentity]::GetCurrent() and relaunches itself with Start-Process powershell -Verb RunAs if it is not already running as Administrator. Both WinGet and Chocolatey require admin privileges to install software machine-wide.

Package manager detection

Before installing anything, the script verifies that the required package manager is available:

• For WinGet: checks Get-Command winget
• For Chocolatey: checks Get-Command choco

If the package manager is missing, the script prints a clear error with installation instructions and exits without attempting any installs.

The install loop

Apps are defined as a PSCustomObject array — not string-interpolated commands. This means no user input ever reaches a command string. Each app object carries only its display name and verified package ID from the Ninichoco catalog:

$apps = @(
  [PSCustomObject]@{ Name = "Google Chrome"; Id = "Google.Chrome" }
  [PSCustomObject]@{ Name = "Visual Studio Code"; Id = "Microsoft.VisualStudioCode" }
)

foreach ($app in $apps) {
  winget install --id $app.Id --silent --accept-package-agreements --accept-source-agreements
}

Each install is wrapped in a try/catch block. Failures are recorded but do not stop subsequent installs (unless -StopOnError is set).

The summary table

After all installs complete, the script prints a results table:

─────────────────────────────────────────────
 App                    Status
─────────────────────────────────────────────
 Google Chrome          ✓ Installed
 Visual Studio Code     ✓ Installed
 7-Zip                  ✗ Failed
─────────────────────────────────────────────
 2 succeeded · 1 failed

How to run the script

Download the script from Ninichoco, then open PowerShell as Administrator. If your machine blocks unsigned scripts, set the execution policy first:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

Then run the script:

.\install-ninichoco.ps1

Or use the one-liner to download and run in a single command, without saving a file:
