Matching two lists and find uninstall string with Powershell - windows

Question

I have a problem with my Script.
I wanted to make a Script which makes a list of software which is found in a specific registry path
and see if this software equals installed software. and if so it should output me the uninstall string.
but right now it does not work as wanted. it never show me the output I wanted even if its similar. As Example i have the Program Git as Branding and in the software I got Git version 2.26.2 but it wont output the uninstall string when I selected git.
My code is:
$branding = Get-ChildItem "HKLM:\Software\DLR\Branding" | Get-ItemProperty | Select-Object -expandProperty ProgramName
$software = Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall | Get-ItemProperty | Select-Object -ExpandProperty DisplayName
ForEach ($brandinglist in $branding) {
$objCombobox.Items.Add("$brandinglist")
}
$objComboBox_SelectedIndexChanged=
{
$selectme = $objCombobox.SelectedItem
Write-Host $selectme
if ("$selectme" -like "*$software*") {
$uninstall = Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall | Get-ItemProperty | Where-Object {$_.DisplayName -match "$electme" } | Select-Object -Property UninstallString
Write-Host "$uninstall"
}
}

Answer 1

You are trying the -like comparison wrong, in which you compare the selected item to an array of displaynames which doesn't work that way.
Also, there is no reason to get the Uninstall strings and Displaynames using an almost identical code twice.
Try
# get a string array of program names
$branding = Get-ChildItem -Path 'HKLM:\Software\DLR\Branding' | Get-ItemProperty | Select-Object -ExpandProperty ProgramName
$regPaths = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall', 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'
# get an object array of DisplayName and UninstallStrings
$software = Get-ChildItem -Path $regPaths | Get-ItemProperty | Select-Object DisplayName, UninstallString
# fill the combobox with the (string array) $branding
$objCombobox.Items.AddRange($branding)
$objComboBox.Add_SelectedIndexChanged ({
$selectme = $objCombobox.SelectedItem
Write-Host $selectme
# get the objects that have a displayname like the selected item and write out the matching Uninstall strings
$software | Where-Object {$_.DisplayName -like "*$selectme*" } | ForEach-Object {
Write-Host $_.UninstallString
}
})
