Tools for updating to 20H2


With the latest build of windows 10, and the toolbox to update windows 10 to newest version is coded for the 2004, I modified the variable to 20H2, and it fails. Anyone have a new tool to run to update windows 10 to 20H2?


Create a Toolbox to run a powershell script and add the following code. It will update to the latest feature release silently in the background:

$winVer = [System.Environment]::OSVersion.Version.Major
$dir = 'C:\_Windows_FU\packages'
mkdir $dir

if ($winVer -eq 10)
        $webClient = New-Object System.Net.WebClient
        $url = ''
        $file = "$($dir)\Win10Upgrade.exe"
        Start-Process -FilePath $file -ArgumentList '/quietinstall /skipeula /auto upgrade /copylogs $dir'

            echo "This is Not Windows10 OS "
sleep 10

Remove-Item "C:\_Windows_FU" -Recurse -Force -Confirm:$false


Does this script still work for others in SH as PowerShell Tool? Runs so quiet, nothing seems to happen :wink: I know it does create the folder for “_Windows_FU”, downloads Win10Upgrade.exe ok, and then runs it. But waited for few hours, no upgrade. Nothing after reboots. What am I missing?
Am I better off concentrating on what the CMD line is for same Feature update control using something like ABC-UPDATE ?


If you want to see it working, remove the /quietinstall argument.


Are yep works without the /quietinstall option. Seems to get hung up around the EULA or something even though I prompt to /skipeula

I am not alone, read thread of this link towards end - apparently /quiet is broken, and if you try without it will always prompt at the moment for EULA and option to upgrade or create media option


That’s for the MediaCreationTool. A different Microsoft tool. My script is using the Windows10Upgrade tool. Its working perfectly for me on all my PCs.


Thanks Drew
Was my bad. Found all the ones that were paused and not completing updates silently were due to Trend Micro AV needing to be uninstalled prior to Windows Update allowing upgrade to continue.
Uninstalled the AV, then run your script unattended. WORKED. Many thanks


If anyone else is looking for this, I wrote something that will:

  • Not run during the working hours you specify in the script (can be disabled)
  • Checks that it is a Windows 10 PC and that it’s on a version below 20H2
  • Check for available hard disk space
  • Display a notification to the user that it’s happening (can be disabled)
  • Downloads Update Assistant and runs it silently

I basically wanted something that can be safely run, and if I fat-finger it and run it accidentally during working hours or on a server it won’t do any damage. And the notification is a good addition with everyone WFH and more likely to be using the PC at night forgetting the upgrade was agreed.

Code can be found below, but I’ll update it later for 2104 when it’s useable here:

# Set Variables:
$targetVersion = "10.0.19042"
$minimumSpace = 10          # Minimum drive space in GB
$downloadPath = "C:\IT"     # Folder for the download
$logPath = "C:\IT\logs"     # Folder for the Windows setup logs
$updateAssistantURL = "" # URL of the update assistant
$upgradeArguments = "/quietinstall /skipeula /auto upgrade /copylogs " + $logPath
$fileName = $updateAssistantURL.Substring($updateAssistantURL.LastIndexOf("/") + 1)

  Prevent updates during working hours
  - if $workingHoursEnabled is set to true, if the script is run between the specified hours it will terminate
  - prevents accidental in-hours upgrades
$workingHoursEnabled = $true 
$workingHoursStart = 0900
$workingHoursEnd = 1730

  Show pop up to logged in user
  - if true, this will display a pop up to any logged in user
  - if timeout is set to 0, script will *need* user to click OK before script continues
  - so if you want this to be unattended, either set a time for the pop up greater than 0 seconds, or set $popupShow to $false

$popupShow = $true
$popupMessage = "As agreed, a Windows Feature Update is scheduled for your device. This will take 2-4 hours depending on the speed of your machine and your internet. Please save all documents and close your work, leaving your PC turned on and connected to power"
$popupTitle = "Message from Contoso IT Department"
$popupTimeout = 20 

function Get-CurrentVersion {
  $OS = (Get-CimInstance Win32_OperatingSystem).caption
  $currentVersion = (Get-CimInstance Win32_OperatingSystem).version
  if (-Not ($OS -like "Microsoft Windows 10*"))
      Write-Output "This machine does not have Windows 10 installed. Exiting."
  if ($currentVersion -eq $targetVersion)
      Write-Output "OS is up-to-date - no action required. Exiting"
    else {
      Write-Output "OS is out of date, continuing"

function Test-DiskSpace ($minimumSpace){
  $drive = Get-PSDrive C
  $freeSpace = $ / 1GB
  if ($minimumSpace -gt $freeSpace)
          Write-Output "Not enough space for the upgrade to continue. Exiting script."
      } else {
        Write-Output "There is enough free disk space. Continuing."

function Test-WorkingHours($enabled, $startTime, $endTime){
  if ($enabled -eq $true)
        [int]$time = Get-Date -format HHMM
        if ($time -gt $startTime -And $time -lt $endTime)
          Write-Output "Script has been executed within working hours. Exiting script."
        } else {
          Write-Output "Confirmed script has been run outside working hours. Continuing."
      } else {
        Write-Output "Working hours flag disabled. Continuing."

function Get-UpdateAssistant($URL, $path, $log, $file){
# Download File
  If(!(test-path $path))
      New-Item -ItemType Directory -Force -Path $path
      Write-Output "Created download path."
  If(!(test-path $log))
    New-Item -ItemType Directory -Force -Path $log
    Write-Output "Created log path."
  Invoke-WebRequest -Uri $URL -OutFile $path\$file
  Write-Output "Downloaded Update Assistant"

function Show-Message($enabled, $title, $message, $time) {
  if ($enabled -eq $true) {
    $popUp = New-Object -ComObject Wscript.Shell
    Write-Output "Message displayed. Continuing"
    } else {
      Write-Output "Pop up has been disabled. Continuing."

function Start-Upgrade($path, $file, $arguments) {
  Write-Output "Starting upgrade process..."
  Start-Process -FilePath $path\$file -ArgumentList $arguments
  Write-Output "Upgrade process has been started"
  Start-Sleep -s 120 # Pause a little, to make sure the process is started

Test-DiskSpace $minimumSpace
Test-WorkingHours $workingHoursEnabled $workingHoursStart $workingHoursEnd
Get-UpdateAssistant $updateAssistantURL $downloadPath $logPath $fileName
Show-Message $popupShow $popupTitle $popupMessage $popupTimeout
Start-Upgrade $downloadPath $fileName $upgradeArguments

Is there a tool like this for Windows 11?
