Automate your BIOS update in MDT

This universal script will automate your BIOS updates in MDT. In order for this script to work, you will need to configure your MDT deployment share with the following folder structure:

Inside of the BIOS folder, you will need a folder for each model that you are supporting in your deployment. The folder names must match the model name that MDT queries with ZTIGather.
You can run wmic computersystem get model to get this value.

Folder Structure Example:
DeploymentShare$\Scripts\Custom\BIOS\HP EliteBook 8560w

Inside of these folders, you will need to place all the files needed to install your BIOS update. You will also need to create custom files needed to silently install and determine the latest BIOS version.

1st File: BIOS.txt
In this txt file, you will place the BIOS version of the update. This is used to compare the BIOS version installed on the machine and the latest update version.

2nd File: UpgradeBIOS.cmd
In this file you will add all the commands needed to silently install your BIOS update.

REM Setting Current Directory
cd "%~dp0"
WINUPTP.exe -s

Once you have the the folder structure completed, you will want to add a Reboot task to your Task Sequence. With this task, you will need to add an if statement with the following configuration:

Reboot Task Configuration

And now for the actual Powershell script!

# Load MDT Task Sequence Environment and Logs
$TSenv = New-Object -COMObject Microsoft.SMS.TSEnvironment
$logPath = $tsenv.Value("LogPath") 
$logFile = "$logPath\BIOS_Update.log"

# Start the logging 

Write-Output "Logging to $logFile." > $logFile

# Collect data
Write-Output "Collecting Data" >> $logFile
$ScriptRoot = $tsenv.Value("ScriptRoot")
$Model = $TSenv.Value("Model")
$CompBiosVersion = (Get-WmiObject WIN32_BIOS).SMBIOSBIOSVersion
$CurrentBiosVersion = Get-Content "$ScriptRoot\Scripts\Custom\BIOS\$Model\BIOS.txt"
$Installer = "UpgradeBIOS.cmd"

try { 
    Test-Path $CurrentBiosVersion -ErrorAction Stop
catch {
    Write-Output "$CurrentBiosVersion does not exist" >> $logFile

# Checking for BIOS update
if($CompBiosVersion.replace(' ' , '') -eq $CurrentBiosVersion.replace(' ' , '')) {
    Write-Output "BIOS is up to date." >> $logFile
else {
    Write-Output "Updating BIOS $CompBiosVersion to $CurrentBiosVersion." >> $logFile
    Start-Process "cmd.exe" "/c $ScriptRoot\Deploy\Scripts\Custom\BIOS\$Model\$Installer" -Wait
    $tsenv.Value("NeedReboot") = "YES"
    Write-Output "Update has been completed successfully." >> $logFile

Query Available Windows Updates

The following script will allow you to query your available Windows Updates in Powershell and it will export it to a CSV file.

#Specify the location of where you want the CSV to be saved (Ex:\\Fileshare)
$location = "\\SHARE"

$MSsearch = New-Object -ComObject Microsoft.Update.Searcher
$Pending = $MSsearch.Search("IsInstalled=0") 
$Update = $Pending.Updates

$Title = $Update | Select-Object Title | foreach { $_.Title } 

$timeformat= "MM-dd"
$date = (Get-Date).ToString($timeformat)

if($Update.Count -eq 0) {
    Write-Host "There are no updates available for $env:Computername"

else {
    foreach($titles in $title){
        $kb = $titles.split('(')[-1].replace(')','')
        if($kb -like "kb*") {
            $table = New-Object –TypeName PSObject -Property @{ 
                'Title' = $Titles 
                'URL' = "https://support.microsoft.com/en-us/kb/$kb" 
        else {
            $table = New-Object –TypeName PSObject -Property @{ 
                    'Title' = $Titles 
                    'URL' = "Not Available" 
        $table | Select-Object Title, URL | Export-CSV -NoTypeInformation -Append "$location\Report.xml"

How to reinstall all of the default Windows 10 apps

This short loop will reinstall all the default Windows 10 apps.

$pkgname = Get-AppxPackage -AllUsers | foreach { $_.packagefullname }

It’s been a while since I have posted something, so here is a quick little function that can help you track your USPS packages right from your Powershell Console!

Example: Get-TrackingInfo -Trackingnumber YOUR-TRACKING-NUMBER-HERE

    Track your USPS Packages
    Track your USPS Packages right from the Powershell Console
    Get-TrackingInfo -Trackingnumber 555555555555
function Get-TrackingInfo  {
    Param([Parameter(Mandatory=$true)] $TrackingNumber)
    $invoke = (Invoke-Webrequest https://tools.usps.com/go/TrackConfirmAction?tLabels=$TrackingNumber).allelements | Where-Object  {$_.tagname -eq "tr" } 
    $information = $invoke | Select-Object OuterText -Unique -Skip 3

Prevent users from creating Office 365 Groups

The script below will block users in a specified OWA Policy from creating Office 365 groups. The script uses Out-GridView to allow you to select which OWA Policy you want to assign this rule to.

#Office 365 Credentials
$username = "USERNAME"
$password = "PASSWORD"

try {
    #Attempts to connect to Office 365 and install Modules
    Import-Module MSOnline
    $pass = convertto-securestring -String "$password" -AsPlainText -Force 
    $credential = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $pass
    Connect-MsolService -Credential $credential -ErrorAction Stop
    $ExchangeSession = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri "https://outlook.office365.com/powershell-liveid/" -Credential $credential -Authentication "Basic" -AllowRedirection
    Import-PSSession $ExchangeSession >null
catch [Microsoft.Online.Administration.Automation.MicrosoftOnlineException] {
    #Logs error for incorrect password
    Write-Host "Please verify your username and password"
    Write-EventLog -LogName Application -Source "Office 365 Log" -EntryType Error -EventId 1 -Message "OFFICE 365 AUTOMATIC LICENSE ASSIGNMENT`n`nError Connecting to Office 365! Please verify your user name and password"

catch {
    #Log for any other error
    Write-Host "Error Connecting"
    Write-EventLog -LogName Application -Source "Office 365 Log" -EntryType Error -EventId 1 -Message "OFFICE 365 AUTOMATIC LICENSE ASSIGNMENT`n`nError Connecting to Office 365!"
$OWA = Get-OwaMailboxPolicy | Select Identity | Out-Gridview -Title "Select one or more OWA Policies" -PassThru | foreach { $_.Identity } 
if($OWA.count -eq 0) {
    Write-Host "Please rerun the script and select an OWA Policy"
else {
    if($OWA.count -gt 1) {
        foreach($MultiOWA in $OWA) {
            Set-OwaMailboxPolicy -Identity $MultiOWA -GroupCreationEnabled $False
    else {
        Set-OwaMailboxPolicy -Identity $OWA -GroupCreationEnabled $False

Automate your Meraki Client VPN Connection

Cisco does a great job with their documentation but unfortunately they didn’t do so well with explaining how to configure their VPN connection for medium to large scale companies. Their documentation only explains how to configure the connection manually, so I decided to use my Powershell skills to write up something really quick. Luckily for us, this task is extremely simple with Powershell.

The following script will automatically configure your Meraki VPN connection on Windows 10:

$ServerAddress = "VPN SERVER ADDRESS"
$ConnectionName = "VPN CONNECTION NAME"
$PresharedKey = "YOUR PRESHARED KEY"
Add-VpnConnection -Name "$ConnectionName" -ServerAddress "$ServerAddress" -TunnelType L2tp -AllUserConnection -L2tpPsk "$PresharedKey" -AuthenticationMethod Pap -Force

This script can be deployed using GPO, your existing system management system or even added to your images with MDT or SCCM.

I hope this helps someone out!

Automatically join a machine to your domain

This short script will join a machine to your domain. This can be useful as a post start up script that will launch after a machine has been imaged.

$domain = "DOMAIN"
$password = "PASSWORD HERE" | ConvertTo-SecureString -asPlainText -Force
$username = "$domain\USERNAME HERE" 
$credential = New-Object System.Management.Automation.PSCredential($username,$password)
Add-Computer -DomainName $domain -Credential $credential

Operating System Audit

Recently I noticed that Kaseya (our system management system) does not always update the operating system name when a computer has been upgraded. It can take a while for a computer to report back in and provide accurate information. Since we finished up our Windows 10 upgrades, we wanted to be 100% sure that we upgraded all our machines. So to verify this information I wrote a script to find out every machine’s operating system in our network.

Universal Uninstall and Install Script

Recently, I decided to make a Powershell script that will make it easier for larger environments to uninstall and upgrade software. This is a continuation of the script that I wrote a while back ago that can find uninstall strings for 32 and 64bit applications (Link). Similar to the previous script, this script will automatically find the uninstall string for the specified program, but now it will also uninstall the program and install an upgraded version with the install file that you picked.
