March 5, 2022Struggling with Uninstall Script
I've got a script that does just that. I've used this base for a few applications that we've wanted to uninstall with various versions in the environment. $Name = "Dell Command | Update" $Timestamp = Get-Date -Format "yyyy-MM-dd_THHmmss" $LogFile = "$env:TEMP\Dell-CU-Uninst_$Timestamp.log" $ProgramList = @( "HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*", "HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*" ) $Programs = Get-ItemProperty $ProgramList -ErrorAction SilentlyContinue $App = ($Programs | Where-Object { $_.DisplayName -eq $Name -and $_.UninstallString -like "*msiexec*" }).PSChildName Get-Process | ? {$_.ProcessName -eq "DellCommandUpdate"} | Stop-Process -Force $Params = @( "/qn" "/norestart" "/X" "$App" "/L*V ""$LogFile""" ) Start-Process "msiexec.exe" -ArgumentList $Params -Wait -NoNewWindow I use PDQ Deploy to run the uninstall, so logs are put in the temp location of the service account.

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 {$_.DisplayVersion -notlike "3.2*"} |
Select-Object -Property DisplayVersion, UninstallString, PSChildName
ForEach (
SAVer) {
If ($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.

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"

Harm_Veenstra NAUK777 Splitting will work. You might also be able to "cheese" it through using Invoke-Expression. For example:Invoke-Expression -Command '& $($unins.UninstallString)'; Cheers,Lain
