The first 3 commands work Get-Package -Name "*Dell Command*" | Uninstall-Package Get-Package -Name "*Dell Power Manager Service*" | Uninstall-Package Get-Package -Name "*Dell Digital Delivery Services*" | Uninstall-Package I had to use another script I found to remove: Dell SupportAssist Remediation this worked it move the different varations of support assist. $SAVer = Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall | Get-ItemProperty | Where-Object {$_.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 cannot remove Dell Optimizer I have tried the following: Get-Package -Name "*Dell Optimizer*" | Uninstall-Package nothing happens Next I tried to remove from the registry. with the following PowerShell lines $unins = Get-ChildItem "HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall" -ErrorAction SilentlyContinue | Get-ItemProperty | Where-Object {$_.DisplayName -Like "*Dell Optimizer *"} | Select Displayname, Uninstallstring I check to verify the uninstall string or path I then run the following line Start-Process -FilePath $unins.UninstallString -ArgumentList "/S" -Wait and the the error message. when i display the uninstall string i get this but in not sure what this mean or if its related I new to powershell so I find scripts that work but i cannot find a command for this one app DisplayName UninstallString ----------- --------------- Dell Optimizer Service "C:\Program Files (x86)\InstallShield Installation Information\{286A9ADE-A581-43E8-AA85-6F5D58C7DC88}\DellOptimizer.exe" -remove -runfromtemp any help of advise would be great whilst we wait for our imaging server i have to build 40 laptops many
