Set-ItemProperty won't include newlines (powershell)

I'm trying to use set-itemproperty to add an item to: HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Installation Sources

$InstallationSources = Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup" -Name "Installation Sources"
$test = $InstallationSources."Installation Sources" + "C:\Test\I386"
Set-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup" -Name "Installation Sources" "$test"

I can echo $test and it looks fine, several lines of paths with my addition at the end. But when I actually use set-itempproperty, it squishes everything into one line, which doesn't work. Each path needs to have its own line. Even manually added newlines aren't passed in (ie: "`nC:\Test\I386"). Ideas?

Thanks

If you want to preserve newlines then make sure the registry value is of type MultiString otherwise the registry won't allow the newlines AFAICT e.g.:

PS> New-ItemProperty hkcu:\ -Name bar -PropertyType MultiString
PS> Set-ItemProperty hkcu:\ -Name bar -Value "contents`r`nmore contents"
PS> Get-ItemProperty hkcu:\ -Name bar


PSPath       : Microsoft.PowerShell.Core\Registry::HKEY_CURRENT_USER\
PSParentPath :
PSChildName  : HKEY_CURRENT_USER
PSDrive      : HKCU
PSProvider   : Microsoft.PowerShell.Core\Registry
bar          : {contents
               more contents}

$test is an array of strings and powershell is automatically joining them together for you when you say:

"$test"

You need to do the join yourself, providing the correct separator character. i.e.:

Set-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup" -Name "Installation Sources" ($test -join "`n")
