Here's a link to some PowerShell code I've used for Dell and other apps .

I have this issue as I recently updated a Dell lappy Latitude 5420 (no AV, not joined Domain) and reinstalled the Dell command update 6.4.

I ran the Dell command update which updated the BIOS and a few other components (total 6)

• BIOS 1.4 to 1.61
• Embedded controller 1.06 to 1.07.

I performed a full backup using Veeam agent for windows to a USB HDD.

Then as playing around with 2 other new notebooks (Dell lappy Latitude 5420), I decided to restore them to the config as per the backup.

I use Bare Metal restore to “restore” the 2 other lappy, change hostname and rebooted…then I ran Dell command update but it shows no updates (even when things like BIOS is still at 1.4).

So I am guessing that there is some sort of cache to clear for Dell command update ?

This thread prompted me to call Dell Tech Support and ask. Tech Support said I can remove everything except Dell SupportAssist since everything is now included in Dell SupportAssist, which makes sense when you look inside Dell SupportAssist. So, I have uninstalled the following via Control Panel\Programs and Features and restarted when done: Dell Digital Delivery Services (no Dell software purchased)Dell Mobile Connect Drivers (no mobile devices connecting to Windows)Dell SupportAssist RemediationDell Update - SupportAssist Update PluginDell Update for Windows 10 This leaves Dell SupportAssist still installed and working to get device driver updates automatically and/or manually. No mess, no fuss, no micro-freezes. Edit:  A Dell automatic update today, 3/16/20, updated Dell SupportAssist installed 1/24 191 MB 3.4.1.49 to 3/16 177 MB 3.4.5.366 without incident. Edit:  When I first got the machine, I uninstalled McAfee antivirus and the Killer Control Center.  To uninstall Killler, you run Rivet Networks' uninstaller and then re-install their drivers only package.  And I uninstalled a few other junk apps in the Start Menu.

Uninstalling Dell SupportAssist Remediation should only be done if you're certain you no longer want it on your system.

Had a simaler issue myself. I was still able to remove it from the settings menu. I found that getting the IdentifyingNumber was more effective with msiexec.exe. I was using this with a deployment system to remove and update Dell command update.

$APP_ID = Get-WmiObject -Class Win32_Product -Filter "Name = 'Dell Command | Update for Windows Universal'"| Select-Object -Expandproperty IdentifyingNumber
if(-not $application){
    Write-host "DCU not Detected"
}else{
  Start-Process "C:\Windows\System32\msiexec.exe" -ArgumentList "/x $APP_ID /passive /qn /noreboot" -Wait

  write-host "DCU uninstalled"
}

hope this helps
