r/PowerShell on Reddit: Struggling with Uninstall Script
May 7, 2021 -

Hello All,

I'm trying to write a script that searches for any install of a specific application (Dell Command | Update) in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall. I'm trying to avoid using get-wmiobject. All I really want is for the application's GUID to be piped into a variable, so I can use it to make my own uninstall string with my own arguments. I can't seem to get this right or find an example online of this. Has anyone solved this already and can share?

I used to pull msiexec uninstall strings from the registry and make wmi calls. Now I like to leverage get-package as it displays a bunch of good information about installed applications. Here is my one liner for uninstalling start-process -FilePath msiexec.exe -ArgumentList "/x $((Get-Package | Where-Object {$_.Name -eq "Dell Command | Update for Windows 10"}).fastpackagereference) /qn /norestart"

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

So I am having the exact opposite issue. I was able to get the newer versions to remove, but anything that returned "C:\Program Files\Dell\SupportAssist\uninstaller.exe /arp" as the UninstallString is failing in my automation as I can't get the prompt to not display (I have around 700 agents to remove this crap from, some with multiple versions, so I feel your pain).

For the newer versions, I used:

$SAVer = Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall  |
    Get-ItemProperty |
        Where-Object {$_.DisplayName -match "SupportAssist" } |
        Where-Object {$_.DisplayVersion -notlike "3.2*"} | 
            Select-Object -Property DisplayVersion, UninstallString, PSChildName

ForEach ($ver in $SAVer) {

    If ($ver.UninstallString) {

        $uninst = $ver.UninstallString
        & cmd /c $uninst /quiet /norestart

    }
}

I am going to look into the method you are showing for the older version (2.0 and earlier) to see if this resolves my issue. Hopefully my code snippet will help with yours. Cheers.

Ran into a similar problem. I had a bunch of computers all with different versions of Support Assist. I compiled this from a few different sources. So far I have had really good success. I am using PDQ deploy. I am not the most PowerShell proficient but perhaps this will help.
