    }
})

# Auto-run on load
$form.Add_Shown({
    $btnRun.PerformClick()
})

[void]$form.ShowDialog()

How to use it:

- Save the Script
  • Open Notepad
  • Paste the GUI script (the one in your canvas)
  • Save as: AD_PreCheck_GUI.ps1

Make sure:

    • File type = All Files
    • Extension = .ps1 (not .txt)
- Open PowerShell (Admin)
  • Click Start
  • Search: PowerShell
  • Right-click → Run as Administrator

- Allow Script Execution (Temporary) 
    Run Script:
    Set-ExecutionPolicy Bypass -Scope Process

Note: This only works for current session (safe)

- Navigate to Script Location
    Example: cd C:\Scripts

- Run the GUI Tool
    Script: .\AD_PreCheck_GUI.ps1

- How the GUI Works
    When it opens:
    Auto-run: Pre-check runs automatically on startup
    Run Pre-Check Button: Click anytime to re-check

- Understand Output
Example (Good Environment)

        Admin rights OK
        AD Module installed
        Domain connected
        Domain Controller reachable
        AD read permission OK
        Execution Policy: RemoteSigned
        Time sync service OK

        ✓  Environment ready for AD automation

Example (Issues Found)

        Not running as Administrator
        AD Module missing
        Machine not domain joined

        ✘  Environment NOT ready

====== Few Important Reason for Errors ======

Not admin         ➜ Run PowerShell as Administrator
AD module missing ➜ Install RSAT
Not domain joined ➜ Join system to domain
No DC reachable   ➜ Check network / VPN
No permission     ➜ Contact AD admin

How to  Make it one-click tool

Option 1: Right-click file → Create Shortcut

Option 2(Best): Create a .bat file

Bat File script: 
powershell -ExecutionPolicy Bypass -File "C:\Scripts\AD_PreCheck_GUI.ps1"
