Script for Automatic Driver Installation after reloading Windows

[0x70369]

Hello, everyone, I hope you all are doing fantastic.

I originally posted this on Issues, but @ruxunderscore instructed me to post this here so more people would see it.

After watching @ChrisTitusTech's video on drivers, I wondered if there's a way to install multiple drivers at once after reloading my system. Finding no way to do so without using 3rd-party software or installing one by one in Device Manager, I decided to create a simple PowerShell script that does this process, using the .inf files in a folder specified by the user.

I'm not at all familiar with PowerShell programming (I asked ChatGPT for help), but the end result looks pretty solid (for a starting point).

Some parts of the script are commented out. The reason is that they didn't work as expected and I lack the knowledge to fix them. I'm sure some people here will make A LOT of improvements to this (maybe a better version will be added to MicroWin?).

What isn't working yet?
1- The script doesn't accept paths with spaces, even with single or double quotes;
2- The script doesn't show a list of drivers that failed to install, if that happens, nor does it show the error messages that pnputil.exe might give;

Feel free to add more features that you may come up with, I hope this evolves and becomes a tool with the same quality as WinUtil itself :)

Here is the code:

    Write-Host "Please open an elevated PowerShell prompt and try again." -ForegroundColor Red
    Exit
}

# Prompt the user to input the path to the drivers folder
do {
    $driverFolderPath = Read-Host "Enter the path to the drivers folder (e.g., 'C:\Users\Admin\Drivers')"

    # Verify that the specified folder exists
    if (-not (Test-Path $driverFolderPath)) {
        Write-Host "The specified folder does not exist." -ForegroundColor Red
        Write-Host "Please make sure you entered the correct path." -ForegroundColor Red
    } else {
        # Get a list of driver files in the folder
        $driverFiles = Get-ChildItem -Path $driverFolderPath -Recurse -Include *.inf

        # Check if any driver files were found
        if ($driverFiles.Count -eq 0) {
            Write-Host "No driver files (.inf) were found in the specified folder." -ForegroundColor Red

        }
    }
